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 in one second, and is equal to exactly 2997 ..more definition+
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 approximately 9 trillion kilometers or 6 trillion ..more definition+
