Presentation Transcript

One light year is equal to the distance traveled by light in one year (through empty space).

  • One light year = 1 ly

  • = 6 trillion miles

  • = 9.5 trillion kilometers



  • ___________ = _____________ x _____________


  • Calculating a light year

    Using the formula d = vt, with

    v = c = 3.00 x 105 km/s

    t = one year = 3.15 x 107 s

    1 ly = 3.0 x 105 x 3.15 x 107 or


    Some interesting distances:To star nearest the sun….4 lyTo edge of our galaxy.…. 50,000 lyTo nearest galaxy .......…. 2,000,000 ly
