The third planet from the sun, Earth is a waterworld, with two-thirds of the planet covered by ocean. Earth's surface rotates about its axis at 1, feet per second meters per second — slightly more than 1, mph 1, kph — at the equator.

The planet zips around the sun at more than 18 miles per second 29 km per second. The fourth planet from the sun, is a cold, dusty place.

The dust, an iron oxide, gives the planet its reddish cast. Mars shares similarities with Earth: It is rocky, has mountains and valleys, and storm systems ranging from localized tornado-like dust devils to planet-engulfing dust storms.

It snows on Mars. And Mars harbors water ice. Mars' atmosphere is too thin for liquid water to exist on the surface for any length of time.

Scientists think ancient Mars would have had the conditions to support life, and there is hope that signs of past life — possibly even present biology — may exist on the Red Planet.

The fifth planet from the sun, Jupiter is huge and is the most massive planet in our solar system. Its swirling clouds are colorful due to different types of trace gases.

A big feature is the Great Red Spot, a giant storm which has raged for hundreds of years. Jupiter has a strong magnetic field, and with dozens of moons, it looks a bit like a miniature solar system.

The sixth planet from the sun is known most for its rings. When Galileo Galilei first studied Saturn in the early s, he thought it was an object with three parts.

Not knowing he was seeing a planet with rings, the stumped astronomer entered a small drawing — a symbol with one large circle and two smaller ones — in his notebook, as a noun in a sentence describing his discovery.

More than 40 years later, Christiaan Huygens proposed that they were rings. The rings are made of ice and rock. Scientists are not yet sure how they formed.

The gaseous planet is mostly hydrogen and helium. It has numerous moons. The seventh planet from the sun, Uranus is an oddball. Astronomers think the planet collided with some other planet-size object long ago, causing the tilt.

The tilt causes extreme seasons that last plus years, and the sun beats down on one pole or the other for 84 Earth-years.

Uranus is about the same size as Neptune. Methane in the atmosphere gives Uranus its blue-green tint. It has numerous moons and faint rings.

The eighth planet from the sun, Neptune is known for strong winds — sometimes faster than the speed of sound. Neptune is far out and cold.

The planet is more than 30 times as far from the sun as Earth. It has a rocky core. Neptune was the first planet to be predicted to exist by using math, before it was detected.

Irregularities in the orbit of Uranus led French astronomer Alexis Bouvard to suggest some other might be exerting a gravitational tug.

German astronomer Johann Galle used calculations to help find Neptune in a telescope. Neptune is about 17 times as massive as Earth.

Once the ninth planet from the sun, Pluto is unlike other planets in many respects. It is smaller than Earth's moon.

Its orbit carries it inside the orbit of Neptune and then way out beyond that orbit. From until early , Pluto had actually been the eighth planet from the sun.

Pluto will stay beyond Neptune for years. New Horizons' Pluto Flyby: Latest News, Images and Video ]. The orbit of Neptune is 2.

The strange world's orbit is about times farther from the sun than the Earth's orbit is from the star. Interaction between a close-in planet's magnetic field and a star can produce spots on the star in a similar way to how the Galilean moons produce aurorae on Jupiter.

Earth's magnetic field results from its flowing liquid metallic core, but in massive super-Earths with high pressure, different compounds may form which do not match those created under terrestrial conditions.

Compounds may form with greater viscosities and high melting temperatures which could prevent the interiors from separating into different layers and so result in undifferentiated coreless mantles.

Forms of magnesium oxide such as MgSi 3 O 12 could be a liquid metal at the pressures and temperatures found in super-Earths and could generate a magnetic field in the mantles of super-Earths.

Hot Jupiters have been observed to have a larger radius than expected. This could be caused by the interaction between the stellar wind and the planet's magnetosphere creating an electric current through the planet that heats it up causing it to expand.

The more magnetically active a star is the greater the stellar wind and the larger the electric current leading to more heating and expansion of the planet.

This theory matches the observation that stellar activity is correlated with inflated planetary radii. In August , scientists announced the transformation of gaseous deuterium into a liquid metallic form.

This may help researchers better understand giant gas planets , such as Jupiter , Saturn and related exoplanets, since such planets are thought to contain a lot of liquid metallic hydrogen, which may be responsible for their observed powerful magnetic fields.

In , two independent teams of researchers came to opposing conclusions about the likelihood of plate tectonics on larger super-Earths [] [] with one team saying that plate tectonics would be episodic or stagnant [] and the other team saying that plate tectonics is very likely on super-Earths even if the planet is dry.

If super-Earths have more than 80 times as much water as Earth then they become ocean planets with all land completely submerged.

However, if there is less water than this limit, then the deep water cycle will move enough water between the oceans and mantle to allow continents to exist.

Large surface temperature variations on 55 Cancri e have been attributed to possible volcanic activity releasing large clouds of dust which blanket the planet and block thermal emissions.

However, the mass of the object is not known; it could be a brown dwarf or low-mass star instead of a planet. The brightness of optical images of Fomalhaut b could be due to starlight reflecting off a circumplanetary ring system with a radius between 20 and 40 times that of Jupiter's radius, about the size of the orbits of the Galilean moons.

The rings of the Solar System's gas giants are aligned with their planet's equator. However, for exoplanets that orbit close to their star, tidal forces from the star would lead to the outermost rings of a planet being aligned with the planet's orbital plane around the star.

A planet's innermost rings would still be aligned with the planet's equator so that if the planet has a tilted rotational axis , then the different alignments between the inner and outer rings would create a warped ring system.

In December a candidate exomoon of a rogue planet was announced. Atmospheres have been detected around several exoplanets. The first to be observed was HD b in KIC b is a small rocky planet, very close to its star, that is evaporating and leaving a trailing tail of cloud and dust like a comet.

In May , glints of light from Earth , seen as twinkling from an orbiting satellite a million miles away, were found to be reflected light from ice crystals in the atmosphere.

Tidally locked planets in a 1: Such a planet could resemble an eyeball with the hotspot being the pupil. As more planets are discovered, the field of exoplanetology continues to grow into a deeper study of extrasolar worlds, and will ultimately tackle the prospect of life on planets beyond the Solar System.
