Question

The second biggest planet of the solar system has:
A. lowest density
B. density equal to water
C. highest density
D. density equal to earth

Answer 1

Hint: The decreasing order of densities of planets in the solar system is Earth > Mercury > Venus > Mars > Neptune > Jupiter > Uranus > Saturn.

Complete step by step solution:
The biggest planet in our solar system is Jupiter, but the title for the second biggest planet in our solar system goes to Saturn and it has the lowest density. Saturn has the lowest density among all planets.
Hence, the correct option is A.

Additional Information: If one could find a big enough body of water for it to float on. Saturn is very large and is the second largest planet in the solar system. However it is made up mostly of gas and is less dense than water.

Note: The density of Saturn is very low because it is made up of gases and is not solid like earth. This makes Saturn very light for its size. Actually, Saturn has the lowest density of all the planets in our solar system even lower than the density of water. Since it is lighter than water, it can float on water. None of the other planets in the solar system can do this because they have a higher density than water. Saturn has the lowest density of all the planets, which means that it does not weigh as much for its size as the other planets are.
