   How many kilometers are in a light year?

   • It turns out that’s only mostly true, because sometimes it does, or gets pretty close. For example, a tiny BB of a star just a couple of dozen kilometers across has shot out a pretty straight beam of matter and antimatter that stretches for a staggering 7 light-years — 70 trillion kilometers!

   A light year (symbol: ly) [1] is the distance that light travels in empty space in one year. Since the speed of light is about 300,000 km per second (about 186,000 miles per second), then a light year is 9.46 trillion kilometers (about 5.87 trillion miles ), for AU, one light year is 63,241 AU. [2] A light year is not a length of time.

   light-year, in astronomy, the distance traveled by light moving in a vacuum in the course of one year, at its accepted velocity of 299,792,458 metres per second (186,282 miles per second). A light-year equals about 9.46073 × 10 12 km (5.87863 × 10 12 miles), or 63,241 astronomical units. About 3.262 light-years equal one parsec.
