An Astronomical Unit is the distance between Earth and the Moon.

The statement is false. An astronomical unit (AU) is not the distance between Earth and the Moon. An astronomical unit is a unit of length used in astronomy to describe the average distance between Earth and the Sun. It is approximately equal to the mean distance from the Earth to the Sun. As of the International Astronomical Union's definition, 1 astronomical unit is defined as exactly 149,597,870.7 kilometers (about 93 million miles). The average distance from the Earth to the Moon is much smaller than this, typically around 384,400 kilometers (about 238,855 miles). Therefore, the astronomical unit is a measure of the Earth-Sun distance, not the Earth-Moon distance.
