Webadjective. [22] In 1868 an English journal labelled the light-year as a unit used by the Germans. [5] From this, the following conversions can be derived. [8] The product of Simon Newcomb's J1900.0 mean tropical year of 31556925.9747 ephemeris seconds and a speed of light of 299792.5km/s produced a light-year of 9.4605301015m (rounded to the seven significant digits in the speed of light) found in several modern sources[9][10][11] was probably derived from an old source such as C. W. Allen's 1973 Astrophysical Quantities reference work,[12] which was updated in 2000, including the IAU (1976) value cited above (truncated to 10 significant digits).[13]. 2 a : being one in particular early one morning The Grand Canyon is one place I'd WebLight-year is the distance light travels in one year.
