The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume.
Jupiter's mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth's diameter.
The planet Jupiter is the fifth planet out from the Sun, and is two and a half times more massive than all the other planets in the solar system combined.
It is made primarily of gases and is therefore known as a “gas giant”.
