Microparsec (μpc) is a unit of distance one-millionth of a parsec, about 30 gigameters, 1.7 light-minutes, or about 1⁄5 astronomical unit. This unit can be used in alternative to astronomical unit and gigameter to measure companion distances from the star, such as planets or companion stars. For example, Earth's distance from the Sun is 4.85 μpc while the nearest exoplanet Ixionidae is just 0.203 μpc from the parent star Alpha Centauri B.
