Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
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.
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.
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.
