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+
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+
