The Lunar Laser Ranging array set up by Apollo astronauts still measures
the distance between the Earth and the Moon.

As the Moon orbits the Earth, the distance between these two bodies is
always changing. At its closest, it's about 225,000 miles (360,000 km) and
at its farthest, it's about 250,000 miles (405,000 km). Scientists can keep
track of the precise distance between the Earth and the Moon thanks to the
Lunar Laser Ranging experiment, set up by the Apollo 11 astronauts in 1969.
