The two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and helium, with 75% of their mass being hydrogen and 25% helium. Because of its relative proximity to Earth, it is the largest planet seen in the night sky. Certainly their compositions are dominated by different elements. They are characterized by their dense, rocky composition. The cratered surface is hot with surface temperatures around 900 F (482 C), the product of a runaway greenhouse effect. Astronomical bodies retain an atmosphere when their escape velocity is significantly larger than the average molecular velocity of the gases present in the atmosphere. This is a small planet with a very low density that may have a thick gas atmosphere, but it could have a rocky planet beneath that atmosphere. There are numerousother giant planets found orbiting other distant stars with one example beingKepler-10c.

Pluto was reclassified as a dwarf planet in 2006. The planets in our solar system exhibit a wide range of diversity, from giant gas-dominated worlds like Jupiter and Saturn to small, barren balls of rock like Mercury.
