Name the largest planet in the solar system.
(a) Neptune
(b) Saturn
(c) Jupiter
(d) Earth

Hint – The smaller, inner planets include Mercury, Venus, Earth, and Mars. The inner planets are called rocky and have diameters of less than 13,000 kilometers. The outer planets include Jupiter, Saturn, Uranus, and Neptune. Relative size means how big the planets are when compared to each other and the sun.

Complete step-by-step answer:
Now, as we know that there are 8 planets in our solar system.
The ascending order of their sizes are given below,
Mercury < Mars < Venus < Earth < Neptune < Uranus < Saturn < Jupiter.
The diameters of the planet is shown in the table below,



So the largest planet amongst the nine planets is Jupiter.
Hence option (C) is correct.

Note – One interesting fact about Jupiter is that it is called a failed star because it is made of the same elements (hydrogen and helium) as the sun, although it is about 11 times the earth’s diameter but still it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars and It is said that Jupiter is so big that over 1300 Earths could even fit inside of it and it will still be able to exist.
