It takes about 3,638,768,483 years so it'll take a super long time!
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
Sirius 8.6 yearsBarnards Star 6 years
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
Stars don't travel to earth. But the light and other radiation that they emit spreads out in every direction from the star, and some of it eventually hits the earth. Starting out from the star, it takes the light 1 year to reach the earth for every 5,878,700,000,000 miles it has to cover to get here.
Easy answer: it would take 72 years.
How long will depend on the velocity. The closest star would be 4.24 light years away
It takes approx. 8 and half minutes to reach earth
4.37 years. the star is Alpha Centauri ---- That's wrong. The closest star is the sun and it takes 8.3 minutes for light to reach us. when phrased nearest star it can be a trick question.. Alpha Centauri is the nearest star besides the Sun.
A light-year is the distance light travels in a year. Therefore, if a certain star is "x" light-years from Earth, then it takes light "x" years to get fromthe star to us. Or the other way round.
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.
Traveling at the speed of light, it would take a spacecraft 40 years to reach a star located 40 light-years away from Earth.
