COMMENTS

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

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

LINKS

Table of n, a(n) for n=16..31.

FORMULA

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

299792458 * 365.25 * 24 * 60 * 60 = 299792458 * 31557600 = 9460730472580800. - Omar E. Pol, Aug 31 2012

EXAMPLE

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