From the sun (sol) about 8 minutes and 12 seconds... From other stars, MUCH longer, over four years from the closest one (Proxima Centauri).

That would all depend on where the light starts from.
However, the speed of light is 299,792,000 m/s.
If you take the distance in question (from the light source to the earth) and divide it by the speed of light, you will come up with a time in seconds for the light to travel.

It takes exactly 8 minutes for light to reach the earth's surface.So when the sun rises it had actually risen 8 minutes before

Again my answer would be a duplicate so all I add is further facts. To the moon is correct with 1.3 seconds. (1.3 up, 1.3 back explains why there is a three second silence between transmissions in the Apollo missions) From the sun 8.3 minuytres, from Jupiter over 8 hours.

Light travels 186,000 miles/second.. thus, it would take four years for light to travel to the Earth

from sun - 8 minutes
from moon - 1.3 seconds
from stars - depends upon the distances someties the star is dead but we can see that because eventhough the light travels fast it takes long time ,
