A light-year is the distance light travels in a year; about 9.5 x 1012 kilometers.
15 light years = 1.42x10^14km
15 light years = 8.81774972 × 1013 miles
The distance light will travel in 15 years. Or about 1.42 x 1014 kilometers.
650 light years equates to 6.14934346 × 10^15 kilometers.
Because you might have seen it in a telescope years ago idkAnother AnswerA light year is a measure of distance. If an object is 15 million light years away, the light you are looking at in this moment was produced 15 million years ago. If a star that far away went supernova at this moment, we wouldn't know it for another 15 million years.The light we see on the surface of our planet from the Sun is a little over 8 minutes old, because it took that light about 8 minutes to travel from the Sun to Earth.
Incredibly far. 640 light years equates to 3.76223988 × 1015 miles.
it took Edison 15-17 years to make the light bulb
Light years and parsecs. A light year is approximately 9,470,000,000,000,000 meters (9.47x10^15) and a parsec is roughly 3.26 light years
Yes, a 15 year old can do light weighted squats. Just never over do yourself.
3262 light years is a measurement of distance, representing the distance that light travels in 3262 years. It is equivalent to about 9.99x10^15 kilometers or approximately 5954.8 trillion miles.
One light-year is about 9 trillion kilometers.Arcturus is a star that is 37 light-years from Earth.
We didn't, the big bang was a rapid expansion of space-time. The formation of the universe, not a literal explosion of matter. Really good question though.
