In the s and early s the discovery of several objects in the outer solar system similar in size to Pluto made it all but necessary to come to a definitive definition of a planet.

Such a definition was needed to separate those types of objects like Pluto into a distinct class, otherwise all of the newly found objects would have to be called planets as well.

There have been several additional planets hypothesized throughout history; however, none of these planets has ever been found. The most recent of these theorized planets was Planet X, a supposedly giant planet used to explain the deviations from the predicted orbits of Uranus and Neptune.

Although Planet X has never been found and scientists are still unable to satisfactorily explain the uranian and neptunian orbital discrepancies, the scientific community has almost unanimously come to the conclusion that Planet X does not exist.

Types of planets The planets fall into two categories based on their physical characteristics: the terrestrial planets and the gas giants.

Although the atmosphere is nowhere near as thick as that of any outer planet, it's the thickest of the terrestrial planets, and it consists mostly of sulfuric acid and carbon dioxide.

The density of its atmosphere makes the air pressure at the surface 90 times that of Earth's. The heat and pressure make the planet decidedly inhospitable to life.

Earth, the third planet from the sun and the largest terrestrial planet, is the only planet known to host living beings and the only one known to have liquid water on its surface.

The atmosphere, made of mostly nitrogen, oxygen and carbon dioxide, is crucial to Earth's ability to support life.

Although the surface of the earth is mostly water, the planet also has large landmasses which harbor a stunning variety of ecosystems. Stargazers from antiquity have called Mars, the fourth planet from the sun, Mars, the Red Planet.

The red color of the surface comes from iron oxide or rust in the soil. The topography is characterized by large volcanoes and deep valleys, and Mars experiences frequent planet-wide wind storms.

Some of the surface features of Mars, such as dry river beds, hint to the possibility that water previously existed on the planet and may still flow under the surface.

The planet is colder than Earth, with surface temperatures ranging from to 32 F to 0 C. Further from the sun, past a ring of asteroids, lies the largest planet in our solar system — Jupiter — the first of the gas giant planets.

Its characteristic colored cloud patterns are caused by enormous, swirling storms in its atmosphere, which consists of primarily of hydrogen, helium, methane ammonia and water ice.

The largest and most distinctive of the storms, the Great Red Spot, is larger than Earth. Jupiter has 63 moons and a faint ring system. Saturn, the sixth planet from the sun, is also a gas giant, and it's most impressive feature as seen from afar is an extensive and complex ring system.

The rings orbit the planet in a thin band about a mile thick. OK, Got it. This page provides a brief description of each of the planets and links to dwarf planets of our solar system.

You can also find out about the difference between planets, dwarf planets and small solar system bodies SSSBs here. The planets and the solar system were formed from a huge cloud of gases and dust particles left over when a massive star exploded as a supernova.

The gas drifted in space and it's thought that another supernova explosion nearby may have caused a pressure wave to pass through the cloud that caused clumping to occur.

As the matter clumped together, gravity in that area got stronger which attracted more matter which in turn increased the gravitational pull. As more and more matter fell toward the high density area, due to conservation of momentum it began to spin - rather like water going down a plug hole.

The result was that as the gravity intensified, the spin became faster resulting in a flat disk of gas and dust surrounding a central high density sphere of gas.

Gravity was also working within the disk of rotating gas and dust pulling matter together to form primitive planets within the gas disk.

Eventually the temperature and pressures in the central sphere became so high that the atoms began fusing together nuclear fusion and the Sun ignited producing heat and light and also the solar wind - an out streaming of subatomic particles.

The heat of the Sun and the solar wind immediately began to have an effect on the huge cloud of gas and particles in the disk. Volatile substances such as water ice near the Sun would heat and sublimate into gas, and these and other gases such as hydrogen would be gently accelerated away from the Sun by the solar wind.

At the distance of Jupiter, the temperature the Sun was not high enough to cause water ice to evaporate and so this meant that large quantities of solid material were available to build larger planets.

These planets could therefore attract and keep hold of more of gas from the gas disk. This is one theory as to why the gas giants became so large, and why there is a divide in planet size between the small inner rocky planets and the outer gas giants.

As time continued, the workings of gravity and the solar wind eventually resulted in the solar system becoming as we know it today.

A mostly empty space with eight surviving planets, five dwarf planets, a band of possibly millions of asteroids.

The first, the zodiacal dust cloud , lies in the inner Solar System and causes the zodiacal light. It was likely formed by collisions within the asteroid belt brought on by gravitational interactions with the planets.

The inner Solar System is the region comprising the terrestrial planets and the asteroid belt. The four terrestrial or inner planets have dense, rocky compositions, few or no moons , and no ring systems.

They are composed largely of refractory minerals, such as the silicates—which form their crusts and mantles —and metals, such as iron and nickel, which form their cores.

Three of the four inner planets Venus, Earth and Mars have atmospheres substantial enough to generate weather; all have impact craters and tectonic surface features, such as rift valleys and volcanoes.

The term inner planet should not be confused with inferior planet , which designates those planets that are closer to the Sun than Earth is i. Mercury and Venus.

Mercury 0. Besides impact craters, its only known geological features are lobed ridges or rupes that were probably produced by a period of contraction early in its history.

Hypotheses include that its outer layers were stripped off by a giant impact, or that it was prevented from fully accreting by the young Sun's energy.

Venus 0. It is much drier than Earth, and its atmosphere is ninety times as dense. Venus has no natural satellites. Earth 1 AU from the Sun is the largest and densest of the inner planets, the only one known to have current geological activity, and the only place where life is known to exist.

Mars 1. It has an atmosphere of mostly carbon dioxide with a surface pressure of 6. Asteroids except for the largest, Ceres, are classified as small Solar System bodies [f] and are composed mainly of refractory rocky and metallic minerals, with some ice.

Asteroids smaller than one meter are usually called meteoroids and micrometeoroids grain-sized , depending on different, somewhat arbitrary definitions.

The asteroid belt occupies the orbit between Mars and Jupiter, between 2. It is thought to be remnants from the Solar System's formation that failed to coalesce because of the gravitational interference of Jupiter.

Ceres 2. Ceres was considered a planet when it was discovered in , and was reclassified to asteroid in the s as further observations revealed additional asteroids.

Asteroids in the asteroid belt are divided into asteroid groups and families based on their orbital characteristics.

Asteroid moons are asteroids that orbit larger asteroids. They are not as clearly distinguished as planetary moons, sometimes being almost as large as their partners.

The asteroid belt also contains main-belt comets , which may have been the source of Earth's water. Jupiter trojans are located in either of Jupiter's L 4 or L 5 points gravitationally stable regions leading and trailing a planet in its orbit ; the term trojan is also used for small bodies in any other planetary or satellite Lagrange point.

Hilda asteroids are in a resonance with Jupiter; that is, they go around the Sun three times for every two Jupiter orbits. The inner Solar System also contains near-Earth asteroids , many of which cross the orbits of the inner planets.

The outer region of the Solar System is home to the giant planets and their large moons. The centaurs and many short-period comets also orbit in this region.

Due to their greater distance from the Sun, the solid objects in the outer Solar System contain a higher proportion of volatiles, such as water, ammonia, and methane than those of the inner Solar System because the lower temperatures allow these compounds to remain solid.

For these reasons, some astronomers suggest they belong in their own category, ice giants. The term superior planet designates planets outside Earth's orbit and thus includes both the outer planets and Mars.

Jupiter 5. It is composed largely of hydrogen and helium. Jupiter's strong internal heat creates semi-permanent features in its atmosphere, such as cloud bands and the Great Red Spot.

Jupiter has 79 known satellites. The four largest, Ganymede , Callisto , Io , and Europa , show similarities to the terrestrial planets, such as volcanism and internal heating.

Saturn 9. Saturn is the only planet of the Solar System that is less dense than water. Saturn has 82 confirmed satellites composed largely of ice.

Two of these, Titan and Enceladus , show signs of geological activity. Uranus Uniquely among the planets, it orbits the Sun on its side; its axial tilt is over ninety degrees to the ecliptic.

It has a much colder core than the other giant planets and radiates very little heat into space. Neptune It radiates more internal heat, but not as much as Jupiter or Saturn.

The largest, Triton , is geologically active, with geysers of liquid nitrogen. Neptune is accompanied in its orbit by several minor planets , termed Neptune trojans , that are in resonance with it.

The centaurs are icy comet-like bodies whose orbits have semi-major axes greater than Jupiter's 5. Comets are small Solar System bodies, [f] typically only a few kilometres across, composed largely of volatile ices.

They have highly eccentric orbits, generally a perihelion within the orbits of the inner planets and an aphelion far beyond Pluto. When a comet enters the inner Solar System, its proximity to the Sun causes its icy surface to sublimate and ionise , creating a coma : a long tail of gas and dust often visible to the naked eye.

Short-period comets have orbits lasting less than two hundred years. Long-period comets have orbits lasting thousands of years.

Short-period comets are thought to originate in the Kuiper belt, whereas long-period comets, such as Hale—Bopp , are thought to originate in the Oort cloud.

Many comet groups, such as the Kreutz Sungrazers , formed from the breakup of a single parent. Beyond the orbit of Neptune lies the area of the " trans-Neptunian region ", with the doughnut-shaped Kuiper belt, home of Pluto and several other dwarf planets, and an overlapping disc of scattered objects, which is tilted toward the plane of the Solar System and reaches much further out than the Kuiper belt.

The entire region is still largely unexplored. It appears to consist overwhelmingly of many thousands of small worlds—the largest having a diameter only a fifth that of Earth and a mass far smaller than that of the Moon—composed mainly of rock and ice.

This region is sometimes described as the "third zone of the Solar System", enclosing the inner and the outer Solar System. The Kuiper belt is a great ring of debris similar to the asteroid belt, but consisting mainly of objects composed primarily of ice.

Though it is estimated to contain anything from dozens to thousands of dwarf planets, it is composed mainly of small Solar System bodies.

Many of the larger Kuiper belt objects, such as Quaoar , Varuna , and Orcus , may prove to be dwarf planets with further data. The Kuiper belt can be roughly divided into the " classical " belt and the resonances.

The first resonance begins within the orbit of Neptune itself. The classical belt consists of objects having no resonance with Neptune, and extends from roughly When discovered in , it was considered to be the ninth planet; this changed in with the adoption of a formal definition of planet.

Pluto has a relatively eccentric orbit inclined 17 degrees to the ecliptic plane and ranging from Pluto has a resonance with Neptune, meaning that Pluto orbits twice round the Sun for every three Neptunian orbits.

Kuiper belt objects whose orbits share this resonance are called plutinos. Charon, the largest of Pluto's moons , is sometimes described as part of a binary system with Pluto, as the two bodies orbit a barycentre of gravity above their surfaces i.

Makemake Makemake is the brightest object in the Kuiper belt after Pluto. It was assigned a naming committee under the expectation that it would prove to be a dwarf planet in Haumea The scattered disc, which overlaps the Kuiper belt but extends out to about AU, is thought to be the source of short-period comets.

Scattered-disc objects are thought to have been ejected into erratic orbits by the gravitational influence of Neptune's early outward migration.

SDOs' orbits are also highly inclined to the ecliptic plane and are often almost perpendicular to it. Some astronomers consider the scattered disc to be merely another region of the Kuiper belt and describe scattered disc objects as "scattered Kuiper belt objects".

It is the most massive of the known dwarf planets. It has one known moon, Dysnomia. Like Pluto, its orbit is highly eccentric, with a perihelion of The point at which the Solar System ends and interstellar space begins is not precisely defined because its outer boundaries are shaped by two forces, the solar wind and the Sun's gravity.

The limit of the solar wind's influence is roughly four times Pluto's distance from the Sun; this heliopause , the outer boundary of the heliosphere , is considered the beginning of the interstellar medium.

The outer boundary of the heliosphere, the heliopause , is the point at which the solar wind finally terminates and is the beginning of interstellar space.

The shape and form of the outer edge of the heliosphere is likely affected by the fluid dynamics of interactions with the interstellar medium as well as solar magnetic fields prevailing to the south, e.

Due to a lack of data, conditions in local interstellar space are not known for certain. It is expected that NASA 's Voyager spacecraft , as they pass the heliopause, will transmit valuable data on radiation levels and solar wind to Earth.

Mike Brown , who discovered the object in , asserts that it cannot be part of the scattered disc or the Kuiper belt because its perihelion is too distant to have been affected by Neptune's migration.

The second unequivocally detached object, with a perihelion farther than Sedna's at roughly 81 AU, is VP , discovered in Its aphelion is only half that of Sedna's, at — AU.

It is thought to be composed of comets that were ejected from the inner Solar System by gravitational interactions with the outer planets.

Oort cloud objects move very slowly, and can be perturbed by infrequent events, such as collisions, the gravitational effects of a passing star, or the galactic tide , the tidal force exerted by the Milky Way.

Much of the Solar System is still unknown. The Sun's gravitational field is estimated to dominate the gravitational forces of surrounding stars out to about two light years , AU.

Lower estimates for the radius of the Oort cloud, by contrast, do not place it farther than 50, AU.

There are also ongoing studies of the region between Mercury and the Sun. Currently, the furthest known objects, such as Comet West , have aphelia around 70, AU from the Sun, but as the Oort cloud becomes better known, this may change.

This revolution is known as the Solar System's galactic year. The Solar System's location in the Milky Way is a factor in the evolutionary history of life on Earth.

Its orbit is close to circular, and orbits near the Sun are at roughly the same speed as that of the spiral arms.

Because spiral arms are home to a far larger concentration of supernovae , gravitational instabilities, and radiation that could disrupt the Solar System, this has given Earth long periods of stability for life to evolve.

Near the centre, gravitational tugs from nearby stars could perturb bodies in the Oort cloud and send many comets into the inner Solar System, producing collisions with potentially catastrophic implications for life on Earth.

The intense radiation of the galactic centre could also interfere with the development of complex life. It is thought to be near the neighbouring G-Cloud but it is not known if the Solar System is embedded in the Local Interstellar Cloud, or if it is in the region where the Local Interstellar Cloud and G-Cloud are interacting.

The bubble is suffused with high-temperature plasma, that suggests it is the product of several recent supernovae.

There are relatively few stars within ten light-years of the Sun. The closest is the triple star system Alpha Centauri , which is about 4.

Alpha Centauri A and B are a closely tied pair of Sun-like stars, whereas the small red dwarf , Proxima Centauri , orbits the pair at a distance of 0.

In , a potentially habitable exoplanet was confirmed to be orbiting Proxima Centauri, called Proxima Centauri b , the closest confirmed exoplanet to the Sun.

The largest nearby star is Sirius , a bright main-sequence star roughly 8. The nearest brown dwarfs are the binary Luhman 16 system at 6.

Other systems within ten light-years are the binary red-dwarf system Luyten 8. Compared to many other planetary systems , the Solar System stands out in lacking planets interior to the orbit of Mercury.

Also, these super-Earths have closer orbits than Mercury. The orbits of Solar System planets are nearly circular.

Compared to other systems, they have smaller orbital eccentricity. This section is a sampling of Solar System bodies, selected for size and quality of imagery, and sorted by volume.

Some omitted objects are larger than the ones included here, notably Eris , because these have not been imaged in high quality.

Saturn, the sixth planet from the sun, is also a gas giant, and it's most impressive feature as seen from afar is an extensive and complex ring system.

The rings orbit the planet in a thin band about a mile thick. The radius of Saturn is about 9. The interior of Saturn, like Jupiter, is made of mostly hydrogen and helium.

Nearing the core, the intense pressure turns the gases into liquids and ultimately into a metallic form that conducts electricity.

While most planets spin on their axis with a slight tilt, the ice giant Uranus spins on an axis parallel to its orbit. With a diameter of 31, miles 50, kilometers , this cold planet is four times the size of Earth and is made of a large atmosphere of methane with a dense core of frozen methane.

Uranus has a faint ring system and 27 moons in its orbit. The blue planet Neptune is the farthest one from the sun and, like Uranus, is a very cold place.

Its surface temperature is a chilly F C. Because of its distance from the sun and its large orbit, one year on Neptune is Earth years.

The atmosphere is mostly methane, which gives the planet its blue color. The cold interior of the planet is mainly methane ice. Like all the outer planets, Neptune, like Uranus, has a diameter roughly four times that of Earth.
