Terrestrial (Rocky) like our planet Earth. Gaseous such as Jupiter. Planets that orbit other stars are referred to asExtrasolar Planets (Exoplanet) Planets that no longer orbit a planet are called Rogue Planets. All the Gas giants in the Solar System have rings, not just Saturn. ...
much remains to be revealed. For example, while Earth and Jupiter lightning strikes in similar ways, where these phenomena occur is wildly different on both worlds. On the gas giant, a large chunk of the thunderstorms have been found in midlatitudes and higher, and in polar regions. They ar...
Neptune is a planet in the same solar system as Earth. It is the furthest planet from the Sun. Neptune is approximately 17 times larger than Earth and is a gaseous planet. Key Ideas:A galaxy is any system of gas, dust, and billions of stars held together by gravitational forces. ...

Why do terrestrial planets have thin atmospheres? What is the atmosphere on the Halley's Comet? Does Jupiter have an atmosphere? On the surface of Mars, the average temperature is -50degC and the atmospheric pressure is only 600. Pa (pascals), which is less than 1% of that of Earth....
But only giant gaseous planets bigger than Jupiter can be found this way, and they are unlikely to harbour life. 14. In the 2010s, ESA plans to launch Darwin, a fleet of four or five interlinked space telescopes that will not only spot small rocky planets, but analyse their atmospheres...

Conditions on the other terrestrial planets, Mercury and Venus, appear to be too harsh to support life as we know it. But it has been conjectured that Europa, the fourth-largest moon of Jupiter, may possess a sub-surface ocean of liquid water and could potentially host life.[79] Recently...
Stars can be scattered outside of their galactic birthplace when a galaxy moves through gaseous material in the space between galaxies, as it orbits the center of the cluster. In the process, drag pushes gas and dust out of the galaxy. However, based on the new Hubble sur...
