%N Decimal expansion of the length of one light-year in meters.

%C This is a function of assigned metrological constants. Regarding these, see A003678 for general context notes, references and links. - _Stanislav Sykora_, Jun 16 2012

%C As defined by the IAU, the light-year is the product of the Julian year, 365.25 days (as opposed to the 365.2425-day Gregorian year) and the speed of light (299792458 m/s, A003678). - _M. F. Hasler_, Oct 31 2014

%F [Speed_of_light_in_vacuum]*[Duration_of_Julian_year], i.e., A003678 * A213612.

%F 299792458 * 365.25 * 24 * 60 * 60 = 299792458 * 31557600 = 9460730472580800. - _Omar E. Pol_, Aug 31 2012

%e Exactly 9.4607304725808*10^15 m = 9.4607304725808 Pm (Peta-meters).

%Y Cf. A003678, A182999, A081799, A019694, A213610, A072915, A213611, A213612, A213613.
