In our solar system; Inner planets are planets that have an orbit which lies within the asteroid belt. Outer planets are planets which have an orbit which lies outside the orbit of the asteroid belt. The asteroid belt lies between Mars and Jupiter. Therefore the inner planets would be in order away form the sun, Mercury, Venus, Earth and Mars. The outer planets in the same order are; Jupiter, Saturn, Uranus and Neptune.
Inner planets are mostly rock and outer planets are mostly gas.
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.
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.
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 inner planets are closest to the sun and the outer planets are farthest from the sun { Answered by a grade 4 student}
the outer planets are gaseous and the inner planets are not
outer planets are gas giants whille inner planets are just rocky planets. that includes that outer planets have significant amount of mass than the inner planets
Location, location, location. Inner planets = Mars and inward (towards the sun); outer planets = Jupiter and outward (away from the sun).
The inner planets are all rocky planets. The outer planets are completely made up of gases. The inner planets are much smaller than the outer planets.
The inner planets are smaller than the outer planets.
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.
