Light Years icon

  • A light year is the distance traveled by light in a vacuum in one year.

  • A light year is a measure of distance and not time. One light year is equivalent to 5.879 x 1012 miles, 9.451 x 1012 kms

  • 1 light year = 365.25 light days (distance travelled by light for that period)
