The Sun

The Sun is an extremely large bundle of gas more than 100 times the diameter of the Earth and more than 300,000 times more massive. [1] To get an idea of the size compared to Earth, picture the Sun the size of a Volleyball, the Earth the size of a pinhead, and Jupiter the size of a nickel! [1] The Sun is large! But then again, there are many things in space way bigger than the Sun! Check out this video to see a comparison of sizes!
