SOLAR SYSTEM

Detailed explanation-1: -Earth. Of the four terrestrial planets, Earth is the largest, and the only one with extensive regions of liquid water. Water is necessary for life as we know it, and life is abundant on Earth-from the deepest oceans to the highest mountains.

Detailed explanation-2: -Jupiter is 11 times larger than Earth in diameter and is the biggest planet in our solar system. Saturn is the next largest, at nine times bigger than Earth. Uranus and Neptune are both roughly four times larger than Earth. Despite their size, the Jovian planets have low densities because of their gaseous composition.

Detailed explanation-3: -But thanks to the Kepler Spacecraft, and it’s ability to observe and collect data from other, distant, solar systems, we’ve found a rocky planet that’s bigger than we thought one could be. The planet, called BD+20594b, is half the diameter of Neptune, and composed entirely of rock.

Detailed explanation-4: -If you were to order the planets by size from smallest to largest they would be Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn and Jupiter. Jupiter and Saturn are sometimes called the gas giants, whereas the more distant Uranus and Neptune have been nicknamed the ice giants.
