A light-year (abbreviation: ly), sometimes referred to incorrectly as a light year, is a unit of length used informally to express astronomical distances. It is approxi ..more definition+
The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space ..more definition+
