Inner planets are mostly rock and outer planets are mostly gas.
The inner planets are closer together than the outer planets are.
the inner planets are closest to the sun and the outer planets are farthest from the sun { Answered by a grade 4 student}
The main difference between the orbits of inner and outer planets is their distance from the Sun. Inner planets (Mercury, Venus, Earth, Mars) have shorter orbits and are closer to the Sun, while outer planets (Jupiter, Saturn, Uranus, Neptune) have longer orbits and are farther away from the Sun. Additionally, outer planets are larger and predominantly composed of gas and ice, while inner planets are smaller and have rocky surfaces.
The distances between the inner planets is smaller than the distances between the outer planets.
The asteroid belt is in-between the inner and outer planets.
Location, location, location. Inner planets = Mars and inward (towards the sun); outer planets = Jupiter and outward (away from the sun).
The main difference is that the inner planets are smaller and are nearer the sun te outer planets are after the earth starting with Mars and ending with Pluto.
The planets revolve in elliptical orbits. The inner planets have orbits 230 million km or less from the Sun. The outer planets have orbits 775 million km or greater.
The inner planets are closer together than the outer ones.
Rotational time of the planets is random (the length of the planet's day), but the outer planets do spin faster than the inner planets.
The inner planets are small, the outer planets are huge in comparison.The inner planets have rocky surfaces, the outer planets are gas giants.All of the outer planets have rings. None of the inner planets does.All of the outer planets have several moons, some of them quite large.
they are the same
