Terameter
A terameter is a unit of length in the metric system equal to 10^12 meters.
History/Origin
The prefix "tera-" for 10^12 was adopted by the CGPM (General Conference on Weights and Measures) in 1960.
Current Use
The terameter is used for measuring distances within our solar system, such as the distances of outer planets from the Sun.
Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
