What are 4 differences between the four inner planets and the four 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.

How do the sizes of the inner and outer planets compare?

The smaller, inner planets include Mercury, Venus, Earth, and Mars. The inner planets are rocky and have diameters of less than 13,000 kilometers. The outer planets include Jupiter, Saturn, Uranus, and Neptune. The outer planets are called gas giants and have a diameter of greater than 48,000 kilometers.

What are the 4 smaller inner planets?

In order of distance from the Sun they are Mercury, Venus, Earth and Mars. Earth is the largest of the inner planets. Venus is almost as big as Earth. Mars and Mercury are smaller.

Why are the 4 outer planets so much bigger than the 4 inner planets?

The Outer Planets These planets are much larger than the inner planets and are made primarily of gases and liquids, so they are also called gas giants. The Sun and the massive outer planets had enough gravity to keep hydrogen and helium from drifting away. All of the outer planets have numerous moons.

Is Mars inside or outside the asteroid belt?

The planets inside the asteroid belt are termed the Inner Planets (or the Terrestrial Planets): Mercury, Venus, Earth, and Mars. The planets outside the asteroid belt are termed the Outer Planets: Jupiter, Saturn, Uranus, Neptune, and Pluto.

What do inner planets have that outer planets don t?

1) The “inner planets” (Mercury, Venus, Earth, Mars) don’t have rings and all of the “outer planets” (Jupiter, Saturn, Uranus, and Neptune) do. The debris have enough momentum that they don’t get pulled all the way into the planet, instead they orbit around it.

What are 4 outer planets?

) In contrast, the four outer planets, also called the Jovian, or giant, planets—Jupiter, Saturn, Uranus, and Neptune—are large objects with densities less than 2 grams per cubic cm; they are composed primarily of hydrogen and helium (Jupiter and Saturn) or of ice, rock, hydrogen, and helium (Uranus and Neptune).…

What is the biggest inner planet?

Earth
Earth: Earth is the third inner planet and the one we know best. Of the four terrestrial planets, Earth is the largest, and the only one that currently has liquid water, which is necessary for life as we know it.

Do inner or outer planets have more mass?

Despite the density differences, the mass is smaller for the inner planets than the outer planets. Another explanation is that although the outer planets are larger, they are primarily composed of gases, which are characteristically less dense than solids.

What are some similarities that inner and outer planets have?

Similarities Between Inner and Outer Planets Both revolve around the sun. Both have moons. Both are spherical in shape. Both orbits on the same planet Both make up the solar system.

How do inner planets differ from outer planets?

Answer: Inner planets tend to be smaller, are solid, and have few moons whereas outer planets are typically larger, made of gas, and have multiple moons and rings around them.

What is the difference between inner and outer planets?

In the Solar System, the inner planets are those that are located closer to the Sun, while the outer planets are those that are further away from it.

How are the inner and outer planets alike and different?

– Inner planets are small in size compared to the size of their counterparts. – Outer planets are made up of gases, while inner planets are made up of solid rocks. – Inner planets don’t have rings orbiting them, while outer planets have.
