One light-year is the distance light travels in a 365-day year. The speed of light is about 186,282.4 miles per second. How long is 2 light-years (in miles)?
Give or take....about 12 trillion miles.
One light year is about 6 trillion miles. So two light years (stand by as I do some calculations in my head) would be aprox. 12 trillion miles.
Two light-years is exactly 11,731,329,000,000 miles. Therefore, one light-year is 5,865,696,000,000 miles. Light travels at 186,000 miles per second, which would be enough to go around the earth precisely 7.4694145545156827587037754677922 times. One light-year is 803929673.7515555872307532057432 times the diameter of Earth.
