Unit Gly [Julian]
Name gigalight-year
Category Length
Details A gigalight-year (Gly) is a unit of length used in astronomy to describe extraordinary distances. It is a combination of the terms "giga" which in the International System of Units (SI) stands for one billion, and "light-year" that represents the distance light travels in a vacuum within one Julian year.

One gigalight-year is equivalent to one billion light-years, and since one light-year is approximately 9.461 x 10^12 kilometers (5.878 x 10^12 miles), one gigalight-year is about 9.461 x 10^21 kilometers (5.878 x 10^21 miles).

This unit is extremely large and is typically used for discussing the scale of the observable universe or distances between galaxy clusters, rather than individual galaxies or stars.
