Question

Name the planet which is least dense among all the planets.
A. Mercury
B. Mars
C. Saturn
D. Jupiter

Answer 1

Hint: Dense planets are those planets whose density is higher. The density of the object is the ratio of the mass and the volume of the object. An object having high density is considered a dense object. The low-density objects are considered as less dense objects.

Complete step by step answer:
The gravitational system that has the Sun and its planet is known as the solar system. Solar system planets are revolving around the Sun due to its gravitational force. There are eight planets revolving around the Sun. The sequence of the planets is, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
The planet that has the least density is Saturn. Saturn is the icy planet of the solar system. It has icy rings around itself. The density of the Saturn is less than that of water. The density of water is \[1\ \text{kg/}{{\text{m}}^{\text{3}}}\]. Density of Saturn is $0.658\ \text{kg/}{{\text{m}}^{\text{3}}}$.

Note:
If the density of the object is less, it is less dense. The oil drop floats on the surface of the water. This is observed because the density of oil is smaller than the density of the water. Although the largest planet is Jupiter, it is not the least dense planet.
