Theoretically, an infinite distance. No one has found a limit so far.

How long does it take light to travel to the nearest star to us?
The nearest star to us is the SUN. It takes light about 8 minutes to travel from the Sun to Eart. #The next nearest star is Alpha Centurii. Light takes about 4.5 years to travel from this star to Earth.
How long does it take for a ray of light to travel from the nearest star to the earth?
8.5 mins
How long does it take for a ray of light to travel from the nearest star to the earth and what is this star called?
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.
How long would it take to travel the solar system at the speed of light to the nearest star?
About 4.2 years.
If you see a star and you went in a spaceship flew out to see the star closer the star is gone if you go back down to earth will the star be there?
It depends how fast you are travelling, and also how long ago the star died; assuming the star JUST died, if you travel there and back at twice the speed of light, you will see it just as it disappears, travel any slower and it will be gone when you get back.However if the star died, say, 10 light years ago, and the distance between earth and the star is 20 light years, you will have to travel at 4 times the speed of light to get back in time to see it disappear.
What is the equation for the travel time to the nearest star at the speed of light?
For example, if a star is at a distance of 5 light-years, it will take 5 years to travel there at the speed of light.
How long would it take to travel to the closest star using a space shuttle?
8.31 minutes @ the speed of light.
How long does it take light to travel from Alpha Centauri the nearest star to our sun to our solar system?
It takes 4.37 years.
Is there any way to reverse time?
no Theoretically, if you could travel faster than the speed of light, you could go back in time. When you look through a telescope at a distant star, you are looking back in time because the light from the star, that you are seeing now, may have taken hundreds of years to travel from the star to your eye. If you can travel faster than light, you could travel to the star and arrive before the light you're seeing now left the star in the first place. Therefore you travelled to a time previous to when the light left.
How long would it take gamma rays from an exploding star to reach earth?
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.
How long would it take a ray of light to travel to Proxima Centauri from the Sun?
Proxima Centauri is 4.2 light years away, so it would take 4.2 years for light from that star to reach us.
If a star is 93 light years away from earth what does this mean?
Light takes 93 years to travel from that star to Earth. That means it's a very long way away, since light travels at 186,000 miles per second (300,000 km per second).
