What is the largest planet that we know of?

    Jupiter!  According to Universe Today:

    Jupiter is 2.5 times more massive than all the other planets in the Solar System combined.

    Let’s take a look at just how big Jupiter is. Jupiter has a mass of 1.8986×1027 kg. For comparison, this is equal to 317 times the mass of the Earth.

    Jupiter’s diameter is 142,984 km at its equator. You could line up 11 Earths side by side, and they wouldn’t quite equal the width of Jupiter.

    But perhaps the most amazing number is Jupiter’s volume. If Jupiter was just a hollow shell, you could fill it up with 1321 Earths, and still have a little room over.


    BUT…Jupiter is actually shrinking!  Every year it compresses down by 2 centimeters.  So, maybe, in several billion years, another planet will be the size leader.
