How Far Is a Light Year?


A light-year is known as a unit of length, equal to just under 10 trillion kilometres. It travels in a vacuum in one Julian year. The size of a light year around the Earth is 6 trillion miles.

Well, let's see: Speed of light = 300,000,000 meters/sec. 1 minute = 60 sec. Lightspeed x 60 sec = (300,000,000 x 60) = 18,000,000,000 meters = 18 million km. = 11,177,000 miles.
This is typically due to varying temperature in the atmosphere causing the different densities of air to refract the light. This effect can be seen in the shimmering above a candle
