What are inner planets and sometimes what are they called?
Inner planets are a group of terrestrial planets that orbit closest to the sun in our solar system. They are also known as the "rocky planets" and include Mercury, Venus, Earth, and Mars. These planets have solid surfaces, are composed mainly of rock and metal, and have relatively high densities compared to the outer gas giants.
Compare and contrast terrestrial and gas planets?
Terrestrial Planets-Rocky Small Few Moons Small(compared to gas giants) Gas Planets - Helium and Hydrogen based Denser cores. Have rings. Many Moons. Very large Longer Revolution time. Comparisons- Planets Under the sun's gravitational pull. Part of Milky Way galaxy
Why are gas giants more oblate than terrestrial planets?
Gas planets are just that - gaseous. This means they are less dense, and more susceptible to centripetal forces. Gas planets also have a tendency to have a faster rotation speed due in part to their large mass. The result is slightly oblate spheroids.
What type of soil does the planet Neptune have?
Neptune is a gas giant, composed mainly of hydrogen and helium, with no solid surface like Earth. As a result, it does not have a soil type like terrestrial planets.
Why are the inner planets different to the outer planets?
The inner planets are all considered rocky planets in that under atmospheric layers, they have a rocky surface. The outer planets are made of gas and liquid, and are called gas giants. They have no solid surface. Also, all the outer planets have rings while the inner planets do not.
Mercury Venus earth and mars make up?
Inner planets orTerrestrial Planets Mercury, Venus, Earth and Mars are the "Inner" planets (as they are inside the asteroid belt), but are also called the terrestrial planets, as they are primarily composed of rock and metal.Mercury, Venus, Earth, and Mars are all inner planets.

Describe a terrestrial planet?
To qualify as a planet, a body has to be approximately spherical (achieving hydrostatic equilibrium under its own gravity), it has to orbit the sun directly and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies.

Which planets don't have rings?
Mercury, Venus, Earth, and Mars. Whether Pluto is considered a planet anymore is under question, but it does not have any rings either. All of the giant planets, Neptune, Uranus, Saturn and Jupiter have rings.
Is Mars terrestrial?
Yes, Mars is terrestrial in the sense that it is a rocky planet like Earth, as opposed to a gas giant like Jupiter or Saturn. However, Mars is also known as an "inferior planet" because its orbit is closer to the Sun than Earth's.
What are bodies that orbit planets called?
Bodies that orbit planets are called satellites or moons. They are natural or artificial objects that revolve around a larger celestial body under its gravitational influence.
What type of soil does the planet Neptune have?
Neptune is a gas giant, composed mainly of hydrogen and helium, with no solid surface like Earth. As a result, it does not have a soil type like terrestrial planets.
Are the eight planets under the sun or above it?
Neither. The eight planets orbit the sun, but in space there is no "under" or "over."
Why are the planets rotating continuously?
There is no friction in space to stop them so they keep on spinning under what is called conservation of angular momentum.
Why are the inner planets different to the outer planets?
The inner planets are all considered rocky planets in that under atmospheric layers, they have a rocky surface. The outer planets are made of gas and liquid, and are called gas giants. They have no solid surface. Also, all the outer planets have rings while the inner planets do not.
