Astronomical Unit
AU
Definition
An astronomical unit (symbol: AU) is a unit of length used in astronomy, equal to the average distance between Earth and the Sun. It is approximately 149.6 million kilometers (93 million miles). The AU is the standard unit for measuring distances within the solar system.
History/Origin
The astronomical unit was first estimated by ancient astronomers using observations of planetary positions. The modern value was determined through radar measurements of Venus and Mercury in the 1960s. It was redefined in 2012 to be exactly 149,597,870,700 meters.
Current Use
The astronomical unit is used throughout astronomy for measuring distances within the solar system, planetary orbits, and spacecraft trajectories. It is essential for space mission planning, planetary science, and understanding the scale of our solar system.
