- The largest planet in our solar system is Jupiter — by volume, 1,000 Earths would fit inside Jupiter. Jupiter's diameter is about a tenth of the Sun's at 88,846 miles (142,984 kilometers).
- Saturn is the second largest planet in our solar system, but it's less dense than any other planet. In fact, it density would allow it to float if you had a body of water large enough.
