In this article, we would like to solve 30 unique MCQs related to our solar system planets in order. As we know, there are thousands of small and large bodies in our solar system, but only eight of them fit the definition of planet; hence, there are a total of eight planets in our solar system which revolve in a fixed orbit around the Sun.
Solar system MCQs
The bodies that revolve around the planet in a fixed orbit are called satellites. There are at least 297 known satellites in our solar system that have been identified by scientists. Jupiter has the largest number of natural satellites in our solar system, whereas Mercury and Venus do not have any satellites. Thus, Mercury and Venus have zero satellites, Earth has one, Mars has 2, Jupiter has 95, Saturn has 82, Neptune has 14, and Uranus has 27 satellites.
