Parsec
A parsec is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years. It is the distance at which one astronomical unit subtends an angle of one arcsecond.
History/Origin
The term "parsec" is a portmanteau of "parallax" and "second," coined by British astronomer Herbert Hall Turner in 1913.
Current Use
The parsec is the preferred unit of distance in astronomy and astrophysics for expressing the distances to stars and galaxies.
X-Unit
An X-unit is a unit of length approximately equal to 1.002 x 10⁻¹³ meters.
History/Origin
The X-unit was proposed by the Swedish physicist Manne Siegbahn in 1919 for measuring the wavelengths of X-rays and gamma rays.
Current Use
The X-unit has been largely replaced by the angstrom and the picometer.
