It depends, but don't worry. Our Sun wont run out in billions of years.
Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 light-years away from Earth.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
star light star bright the first star I see tonight wish I may wish I might take this wish I wish tonight.
The light from a star eight light years away will take eight years to reach Earth.
Easy answer: it would take 72 years.
A Light Year is a measure of distance. If a star is 61 light years away, then it would take light (or radio waves, which travel at the speed of light) 61 years to get there.
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
Sirius 8.6 yearsBarnards Star 6 years
Yes, stars do not stop shining until they run out of resources.
Our Sun is at a distance of 8 light-minutes. The next star outside our Solar System is Proxima Centauri, at a distance of 4.2 light-years.
Well the answer is in the question. A light year is the distance it takes light to travel in one year. If something is a 100 light years away, then it will take light ..........
