It may seem like a question with a simple answer: How far away is the moon? But the distance between Earth and our closest neighbor is more nuanced than a single number.
"The commonly quoted average distance of 384,400 kilometers, or 238,855 miles, is a good approximation," said Craig Hardgrove, an associate professor of Earth and space exploration at Arizona State University and principal investigator on LunaH-Map, a remote mission designed to detect ice deposits on the moon.
