Relative to Earth’s size, sure, but all the giant planets in the solar system have several large spherical moons, hundreds or thousands of km in diameter. These two rocks are small by any planet’s standards.
- onlyrealcuzzo 7y agoWait. That would mean there are moons twice as big as Earth in our solar system. Jupiter has one that's bigger than Mercury, but still almost 10-times smaller than Earth.
- dmurray 7y agoIt does not mean that. Mercury is 5,000 km in diameter.
