How Far Away is the Moon?
The moon floats just above the atmosphere of Earth, right? Not quite. The moon is 238,900 miles (384,400 km) from the Earth, but most depictions do not illustrate this distance to scale. In fact, every planet in the Solar System (this does not include Pluto or any of the planets' moons) could line up in the space between Earth and our moon. Distances in space are often measured using the astronomical unit (AU), which is a unit of length that is roughly the distance from the Earth to the sun.
