Light-minute

Light-minute

A light-minute (also written light minute) is a unit of length. It is defined as the distance light travels in an absolute vacuum in one minute or 17,987,547,480 metres (~18 Gm). Note that this value is exact, since the metre is actually defined in terms of the light-second.

To give an example, the average distance from the Earth to the Sun (or 1 astronomical unit) is about 8.317 light-minutes.
