The siriometer is a rarely used and an obsolete astronomical unit of length, defined to be equal to about one million astronomical units (au). One siriometer is approximately 149.6 petametres; 4.848 parsecs; 15.8 ..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 in one second, and is equal to exactly 2997 ..more definition+
