For light to travel from the sun to earth.
At a distance of 56 million kilometers, light requires 3.1 minutes to reach Mars from Earth.
Vega is relatively close at 25 light years. At one tenth of the speed of light, it would still take 250 years to reach it from our solar system.
An object that is 8,000 light years away from Earth will take 8,000 years to reach us if it travels at the speed of light. Since nothing can travel faster than light according to our current understanding of physics, this distance would require that same amount of time, 8,000 years, for light (or anything traveling at that speed) to cover the distance to Earth.
Assuming the comet is far away in the outer solar system, it would take light approximately 8 minutes to reach Earth from the Sun, and then more time to reach the comet depending on its distance. Traveling at the speed of light, it would take a few minutes to several hours or more to get from Earth to a comet, depending on its specific location in space.
Easy answer: it would take 72 years.
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
8 hours
approximately 8.33seconds
Light travels at about 300,000 metres per second. The time taken for that light to reach us would depend on the stars distance.
Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
Approximately 1.5 seconds.
the earth does not go to the sun or else we would all be burnt to ashes. it takes about 8 minutes for the light from the sun to reach the earth.
If light rays did not travel through space there would be no way for them to reach Earth.
That would depend on which type and form of energy you are referring to. Light energy takes about 8 minutes to reach Earth from the Sun.
25,000 years.
I will not be able to reach the sun in terms of light years as it is within our own solar system. However, light from the sun takes about 8 minutes to reach Earth so you could say it would take about 8 minutes in terms of light years to "reach" the sun.
