Question:
What are some essential differences between planets and stars?
Planets:
A planet can be found revolving around any star. Its inherent gravity has given it a rounded shape. A planet may have one or more satellites of its own. The outer planets and inner planets are the two different categories of planets that exist in our solar system. The planet on the outside of the asteroid belt is known as the outer planet, and the planet inside the asteroid belt is called the inner planet.
