Definition
An astronomical unit (AU) is a unit of length used in astronomy, defined as the average distance from Earth to the Sun, approximately 149,597,870.7 kilometers. A kilometer (km) is a metric unit of length equal to 1,000 meters, widely used globally for terrestrial and scientific measurements.
History
The astronomical unit was first approximated in the 17th century by astronomers like johannes kepler and later refined with parallax measurements in the 18th and 19th centuries. It was formally defined by the International astronomical union in 1976. The kilometer emerged during the french revolution in the 1790s as part of the metric system, standardized for precision in science and engineering.
