Detailed explanation-1: -Saturn is the second biggest planet in our solar system. Similar to Jupiter it has over 60 moons and is made up of different gases. Even though it is a gas giant, it is also the lightest planet. Saturn is so light that it would float in water, if there was an ocean big enough.

Detailed explanation-2: -Saturn’s volume is greater than 760 Earths, and it is the second most massive planet in the solar system, about 95 times Earth’s mass. The Ringed Planet is the least dense of all the planets, and is the only one less dense than water. If there were a bathtub big enough to hold it, Saturn would float.

Detailed explanation-3: -Even though Saturn is the second largest planet, it is the lightest planet in the solar system. The radius of Saturn is about 58, 000 km with a total surface area of 42.7 billion km2. Saturn is mostly liquid hydrogen and helium which have the lowest density on the periodic scale. It’s less dense than water.

Detailed explanation-4: -The hydrogen, helium, and a bit of heavier elements in Saturn take up almost the same space as Jupiter, but Saturn’s mass is half of Jupiter’s. The reason is Jupiter’s strong gravity and its compression.

Detailed explanation-5: -Mercury is the smallest planet in the solar system. Mercury is the closest to the sun therefore it has the highest orbital velocity. Being the smallest planet, Mercury has no atmosphere and no satellite.
