Chapter 32, Problem 3RQ

How are the outer planets are different from the inner planets aside from their location?

To determine

The difference between the inner planets and outer planets.

Answer to Problem 3RQ

The outer planets are far from Sun, so the gravitational force of the Sun on the outer planets is less, while inner planets are near to Sun, so the gravitational force of the Sun on the outer planets is more.

Explanation of Solution

The difference between the inner planets and outer planets are following:

Sr.No.	Inner Planets	Outer Planets
1.	These planets are near to Sun.	These planets are far from Sun.
2.	The gravitational force of the Sun on the inner planets is more.	The gravitational force of the Sun on the outer planets is less.
3.	The inner planets are small, dense and rocky planets.	The outer planets are large size, less dense and gaseous.
4.	The natural satellite of inner planets is less.	The outer planets have more natural satellites.
5.	The inner planets include Mercury, Venus, and Earth And Mars.	The outer planets include Jupiter, Uranus, Saturn and Neptune.

Conclusion:

Therefore, The outer planets are far from Sun, so the gravitational force of the Sun on the outer planets is less, while inner planets are near to Sun, so the gravitational force of the Sun on the outer planets is more.
