What is another word for light minute?
Pronunciation: [lˈa͡ɪt mˈɪnɪt] (IPA) 
A "light minute" is a term used in astronomy to describe the distance that light can travel in a minute. Measuring vast distances in space requires such specialized terms. However, there are a few alternative synonyms to "light minute" that can be used when describing a distance equivalent to a light-minute. One option is to use the more general term 'astronomical unit' (AU). This term describes the distance between the Earth and the Sun and is equal to 8.3 light minutes. Another option is to use "light hour" which is equivalent to 60 light-minutes. Finally, the term "parsec" is often used to describe very large distances. It is equivalent to 19.17 trillion miles or 3.26 light-years.
