Where are the rocky planets?

These planets are located between the Sun and the asteroid belt. Terrestrial planets have a solid planetary surface, making them substantially different from the larger gaseous planets, which are composed mostly of some combination of hydrogen, helium, and water existing in various physical states.

Which rocky planet is least like Earth?

Mercury. Mercury is the smallest terrestrial planet in the solar system, about a third the size of Earth. It has a thin atmosphere, which causes it to swing between burning and freezing temperatures.

What planet is closest to the sun?

Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.

What planet rotates the fastest?

Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.
