It takes light 42.2 years for light from Capella to reach us
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.
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.
Yes but only about 1.3 seconds ago as this is how long light takes to reach us from the Moon.
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.

It takes approximately 8 minutes for the Sun's light to reach Earth.
light takes about eight minutes
About 37 years.
It takes light around 8 minutes and 19 seconds to reach the earth from the sun.
It takes around ten hours to drive from Capella, Qld to the Sunshine Coast. The distance is 874km.

A few kilometers. It takes light about 8 minutes to reach Earth.
It takes light approximately 4.3 years to reach our solar system from Alpha Centauri.
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
A little over 8 minutes. See link.
