Once the light reaches the surface of the Sun, it takes approximately 8 minutes and 20 seconds to reach Earth. This can be calculated by dividing the distance to the Sun by the speed of light: 150,000,000 km / (300,000 km/second).
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the 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.
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.
It takes approximately 8 minutes for the Sun's light to reach Earth.
About 37 years.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
It takes approx. 8 and half minutes to reach earth
along long long long time
approximately 3 seconds.
light takes about eight minutes
