The four inner planets are smaller, denser and warmer than the four outer gas planets. The four gas planets don't have clear surfaces like the four inner rocky planets. Because they are further away, the out gas planets orbit the sun at slower speeds and at slower rates - taking much longer in general. The four outer planets have a very different composition to the inner planets.
However, it was believed that other planets close to another star couldn't be gas giants, but the discovery of a "hot Jupiter" extrasolar planet whose mass is close to or exceeds that of Jupiter orbits within 0.05 AU of it's parent stars, about one eighth of the distance that Mercury orbits the Sun.
the inner planets are rocky and within the aesteroid belt. the outer planets are made from gas and ice and are outside the belt.
The inner planets are between the Sun and the Asteroid Belt, while the outer planets are farther from the Sun than the Belt.
The "inner planets" are the four rocky or "terrestrial" (Earth-like) planets closer to the Sun. The outer planets are the four larger "gas giants".
Inner planets : Mercury, Venus, Earth, Mars
Outer planets : Jupiter, Saturn, Uranus, Neptune
The inner planets are closer together than the outer planets are.
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 distances between inner planets (Mercury, Venus, Earth, Mars) are much smaller compared to the distances between outer planets (Jupiter, Saturn, Uranus, Neptune). The inner planets are closer to each other, with relatively small gaps between their orbits, while the outer planets are much farther apart, with larger gaps between their orbits.
The distance between the inner planets (Mercury, Venus, Earth, Mars) is comparatively smaller than the distance between the outer planets (Jupiter, Saturn, Uranus, Neptune) in our solar system. The inner planets are closer to the Sun and each other, while the outer planets are much farther apart due to the gap between the terrestrial and gas giant planets.
The inner planets and outer planets are separated by the asteroid belt, which lies between Mars and Jupiter in our solar system. The inner planets are Mercury, Venus, Earth, and Mars, while the outer planets are Jupiter, Saturn, Uranus, and Neptune.
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.
Location, location, location. Inner planets = Mars and inward (towards the sun); outer planets = Jupiter and outward (away from the sun).
The asteroid belt is in-between the inner and outer planets.
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.
