How are outer planets diffrent from inner planets?

The Inner Planets (Mercury, Venus. Earth, and Mars) have many differences between the Outer Planets (Jupiter, Saturn, Uranus, and Neptune), some of the main ones as follows: • All the Inner Planets are terrestrial planets, while the Outer Planets are gaseous planets. • Comparably, the Outer Planets are much bigger than the Inner Planets. • Mars, the Inner Planet with the most moons has no more than 2 moons. However, each of the Outer Planets have at the very least 10 moons each. • The Outer Planets have much longer orbital periods than the Inner Planets, due to the fact that they're further away from the Sun. • Venus, the Inner Planet second closest to the Sun, has extremely hot temperature conditions (an average of 870 F or 450 C), but the Outer Planets have very cold weather, all in negative degrees of at least -240 F or -150 C. Also, Venus is the hottest planet, and Uranus is the coldest one.
