Admin What was a major difference in the formation of the inner and outer planets?
All of the inner planets are solid, dense, rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly.
What are the features of the outer planets?
Lesson Summary. The four outer planets are all gas giants made primarily of hydrogen and helium. They have thick gaseous outer layers and liquid interiors. The outer planets have numerous moons, as well as planetary rings.
What are two major differences in composition of the inner and outer planets?
The inner planets are made of rocky material, which has higher density; these are often known as terrestrial (earth-like) planets. The outer planets are made mostly of low density gases; these are often known as Jovian (Jupiter-like) planets.
What are two major differences between the inner and outer planets?
The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
What are three differences between inner and outer planets?
The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
What is the composition of the inner and outer planets?
What are 3 characteristics of the outer planets?
The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
