An astronomical unit (AU) is the average distance between the Earth and the Sun, approximately 93 million miles or 150 million kilometers. Objects within our solar system, such as comets, can be found at distances measured in AUs from Earth. Stars and distant galaxies are much farther away, well beyond the scale of AUs, and artificial satellites orbit much closer to Earth, typically within a few hundred to a few thousand kilometers.
