The astronomical unit is the mean distance from Earth to Sun. It is commonly used for distances in the Solar System. This way, it is easier to imagine the distances, since the meter or kilometer are very small units (an astronomical unit is about 150 million km, or 150 billion meters), and the light year and the parsec are very large units (a light-year is about 63,000 astronomical units, the parsec is even larger). Light-minutes or light-hours might be used instead, within the Solar System, but the astronomical unit has become quite popular.
