The smallest known extrasolar planet that is likely a "gas planet" is Kepler-138d, which has the same mass as Earth but is 60% larger and therefore has a density that indicates a thick gas envelope. [16] A low-mass gas planet can still have a radius resembling that of a gas giant if it has the right temperature. [17]
Similarly to Jupiter, Saturn is not likely to host life. It is a gas giant and the temperatures, pressures, and materials found in it are too dangerous for life. [63] The planet is hydrogen and helium for the most part, with trace amounts of ice water. Temperatures near the surface are near -150 C.
Size of Jupiter compared to Earth and Earth's Moon Jupiter is about ten times larger than Earth ( 11.209 R 🜨 ) and smaller than the Sun ( 0.102 76 R ☉ ). Jupiter's mass is 318 times that of Earth; [ 2 ] 2.5 times that of all the other planets in the Solar System combined.
The prevailing theory is that such planets were formed when larger bodies. Saturn and Jupiter may be gas giants now, but according to some experts, they were once nothing more than tiny pebbles ...
Time-lapse sequence from the approach of Voyager 1 to Jupiter in 1979, showing the motion of atmospheric bands, and the circulation of the Great Red Spot. The momentary black spots are shadows cast by Jupiter's moons. Jupiter's Great Red Spot rotates counterclockwise, with a period of about 4.5 Earth days, [24] or 11 Jovian
The planets as known during classical antiquity: the Moon, the Sun, Mercury, Venus, Mars, Jupiter, and Saturn. Earth analog: A planet or even a superhabitable planet with conditions to be compared with those found on Earth. Teegarden b and c, KOI-4878.01 (unconfirmed) Jupiter analog
Astronomers have identified a planet that’s bigger than Jupiter yet surprisingly as fluffy and light as cotton candy. The gas giants in our solar system — Jupiter, Saturn, Uranus and Neptune ...
A giant planet, sometimes referred to as a jovian planet (Jove being another name for the Roman god Jupiter), is a diverse type of planet much larger than Earth. Giant planets are usually primarily composed of low-boiling point materials (), rather than rock or other solid matter, but massive solid planets can also exist.
