Web12 de jun. de 2013 · π = 1/ d, where the appropriate unit of distance for d is the parsec (pc). We choose this unit and this name, because it is the distance required for a star to have a par allax of one sec ond of arc. A pc is equal to 3.09 × 10 13 km or 3.26 light years. Obviously the nearest stars will have the largest parallaxes. WebAnswer (1 of 4): Speed of light is not used to measure time. We mostly follow earthly time i.e. second, minute, hour, day, year.
