Differences Between Inner and Outer Planets

Eileen Perez, an astrophysicist, explains the differences between inner and outer planets. Inner planets, like Mercury and Mars, are rocky, small, and close to the Sun, with few moons and no rings. Outer planets, such as Jupiter and Neptune, are large gas giants, far from the Sun, with many moons and ring systems. The video covers aspects like location, size, composition, structure, rotation, orbit, and the presence of moons and rings.

Which of the following planets is an inner planet?

• Jupiter

• Saturn

• Earth

• Neptune

Where are the inner planets located in relation to the Sun?

• In the asteroid belt

• Far from the Sun

• Beyond Neptune

How does the size of inner planets compare to outer planets?

• Both are the same size

• Inner planets are smaller

• Outer planets are smaller

• Inner planets are larger

What is the primary composition of inner planets?

• Rock and metal

• Gas

• Ice

• Liquid

What type of atmosphere do inner planets typically have?

• No atmosphere or thin atmosphere

• Thick atmosphere

• Methane-rich atmosphere

• Water-rich atmosphere

How do the rotation speeds of inner planets compare to outer planets?

• Both rotate at the same speed

• Inner planets rotate slower

Why do gas giants have faster rotation speeds?

• They are closer to the Sun

• They have differential rotations

• They are smaller

• They have more moons
