Question

Which of the following statements is correct for the planet Saturn?

• A. It has the longest period of revolution.
• B. It appears reddish in colour.
• C. It is the largest planet of the solar system.
• D. Its density is less than the density of water.

Answer 1

The correct option is D

Its density is less than the density of water.

Saturn has the lowest density of all the planets in the solar system. Its density is 0.687 $g/c{m}^3$ which is less than that of water. If you had a large enough pool of water, Saturn would float in it.

Jupiter is the largest planet in the solar system while Venus has the longest period of revolution. Mars appears reddish in colour because of presence of iron in its soil.
