Kiloparsec
A kiloparsec is a unit of distance used in astronomy, equal to one thousand parsecs.
History/Origin
The parsec was first proposed as a unit of distance in 1913 by British astronomer Herbert Hall Turner. The kiloparsec is a multiple of the parsec used for larger astronomical distances.
Current Use
The kiloparsec is used to measure distances to objects within and around the Milky Way galaxy.
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.
