The equatorial circumference of the Moon is 10,916 km. And the circumference of the Moon in miles is 6,783 miles. So, if you wanted to drive your lunar rover around the Moon and return back where you started, you’d need to travel 10,916 kilometers.
Need some comparison? The equatorial circumference of the Earth is 40,075 km. That makes the size of the Moon’s circumference about 27.24% the size of the Earth.
The Moon isn’t the largest moon in the Solar System – it only has an equatorial radius of 1,737.4 km. The largest moon is Jupiter’s moon Ganymede, with an equatorial radius of 2,634 km. That means Ganymede’s circumference is 16,550 km; bigger than the Moon’s circumference by about 5,634 km.
