What are the inner planets?

The inner planets, also known as terrestrial planets, are the four planets closest to the Sun in our solar system: Mercury, Venus, Earth, and Mars. These planets are characterized by their solid, rocky surfaces and relatively high densities compared to the outer gas giants. Each inner planet has a unique set of characteristics, such as Mercury's extreme temperatures, Venus's thick atmosphere, Earth's abundant liquid water and life, and Mars's evidence of past water.

How many inner planets are there?

There are four inner planets in our solar system: Mercury, Venus, Earth, and Mars. These planets are also known as terrestrial planets because they are solid and rocky in composition, unlike the outer gas giants.

Which inner planet has the shortest year?

Mercury has the shortest year of all the inner planets, taking only about 88 Earth days to complete one orbit around the Sun.

Which inner planet has the thickest atmosphere?

Venus has the thickest atmosphere among the inner planets. Its atmosphere is composed mainly of carbon dioxide with traces of nitrogen and sulfuric acid clouds. The dense atmosphere traps heat, making Venus the hottest planet in our solar system despite not being the closest to the Sun.

Which inner planet has the most moons?

Mercury and Venus do not have any moons. Earth has one moon. Mars has two moons, Phobos and Deimos. Therefore, the inner planet with the most moons is Mars, with its two moons.

Are the inner planets rocky or gaseous?

The inner planets, including Mercury, Venus, Earth, and Mars, are primarily rocky, with solid surfaces and dense compositions.
