Densest planet of Solar system is

Key Points

• Earth is the densest planet in the Solar System, with an average density of about 5.52 grams per cubic centimeter.
• This high density is due to Earth’s core, which is primarily made of iron and nickel.
• The composition of Earth includes a metallic core, a silicate mantle, and a crust, which collectively contribute to its density.
• The planet’s gravity and pressure further compact its interior, increasing its overall density.

Additional Information

• Jupiter: Jupiter is the largest planet in the Solar System, but its density is much lower than Earth's, at 1.33 grams per cubic centimeter. This is because it is primarily composed of hydrogen and helium, making it a gas giant.
• Saturn: Saturn is the least dense planet in the Solar System, with a density of only 0.69 grams per cubic centimeter. It is so light that it would float in water if a body of water large enough were available.
• Mars: Mars, also known as the Red Planet, has a density of 3.93 grams per cubic centimeter. While it is denser than the gas giants, it is less dense than Earth due to its smaller size and composition.
