Which is the largest planet of the solar system?
- A.Saturn
- B.Neptune
- C.Jupiter
- D.Uranus
Correct answer
Explanation
The correct answer is C, Jupiter. Jupiter is the fifth planet from the Sun and the largest of all by both diameter and mass; it is a gas giant of hydrogen and helium. It also has the fastest rotation of any planet, completing a spin in about ten hours, carries the storm called the Great Red Spot, and holds Ganymede, the largest satellite in the solar system.
Option A, Saturn, is the second largest and is known instead for its bright rings and for having the lowest density of any planet. Options B and D, Neptune and Uranus, are the two outermost planets and are much smaller than Jupiter and Saturn; Neptune is the farthest from the Sun and Uranus is the one that rolls on its side. Keep the size order in mind: Jupiter, Saturn, Uranus, Neptune, then the Earth.
