[30] Giant planets are significantly more massive than the terrestrials: Jupiter, Saturn, Uranus, and Neptune. [30] They differ from the terrestrial planets in composition.
A type of exoplanet with a mass only a few times larger than Earth's but with a radius larger than that of Neptune, giving it a very low mean density. Kepler-51b, c and d: Silicate planet: A terrestrial planet that is composed primarily of silicate rocks. All four inner planets in the Solar System are silicon-based. Mercury, Venus, Earth and Mars
[120] [121] Mars has a highly differentiated internal structure, and lost its magnetosphere 4 billion years ago. [122] [123] Mars has two tiny moons: [124] Phobos is Mars's inner moon. It is a small, irregularly shaped object with a mean radius of 11 km (7 mi). Its surface is very unreflective and dominated by impact craters.
