Question

You have learned about the common characteristics of inner planets and outer planets. Explain how these characteristics are verified observations and not just the opinions of scientists.

Answer 1

Answer:

The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer 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.

Answer 2

• The four inner planets are composed of rock and metal and have shorter orbits and slower spin than the outer planets.
• The four outer planets have more extensive moon and ring systems, longer orbits and spins, and are made up mostly of gases and liquids.
• The outer planets are known as gas giants because they are comprised of hydrogen and helium.

• The inner planets, often known as terrestrial planets, are the four planets Mercury, Venus, Earth, and Mars that are nearest to the Sun  They resemble the planet Earth.
• All are rock-like, substantial, and thick. The inner planets don't have any rings. The inner planets are tiny compared to the outer planets. They spin more slowly and have smaller orbits around the Sun.
• The slowest-spinning of all the planets is Venus, which rotates in reverse.
• There was once geological activity on every inner planet.
• All of them are composed of cooled igneous rock with iron cores inside.
• Mars has two tiny, asymmetrical moons whereas Earth has one large, rounded moon. There are no moons on Mercury or Venus.
• The outer planets of our solar system are Jupiter, Saturn, Uranus, and Neptune. The Sun is most distant from these four planets.
• The size difference between the inner and outer planets is substantial. They are also known as gas giants since they are primarily composed of gases.
