How big is the Moon?
The moon is the brightest object seen in our night sky. However, how huge is the moon? The average radius of the moon is 1,079.6 miles (1,737.5 kilometers), while the average diameter is 2,159.2 miles (3,475 km). According to NASA, the moon is less than a third the breadth of our home planet. The equatorial circumference of the moon is 6,783.5 miles (10,917 km). The moon appears to be rather enormous at first glance, but this is only because it is our closest celestial body – around 238,855 miles (384,400 km) distant on average.
The moon is somewhat bigger than one-quarter (27%) the size of Earth, a far greater ratio (1:4) than any other planets and moons. The moon of Earth is the fifth biggest in the solar system.
