And that's another answer...sunlight travels as the speed of light, which is roughly 186,283 miles/second. You know S = 93 million miles is the distance to the Sun. I just gave you the speed V; so how long will it take for sunlight to go that distance S? HINT: T = S/V.

Ricki say: You don't, it takes 8 minutes (about) for the energy from the sun to reach use. The heat you feel "immediately" when you walk outside left the surface of the sun about 8 minutes ago and is just getting here.
-
Chester say: The Sun's light take 8 mins to get to us but it's a constant effect.

DosCentavos say: The warmth you are feeling from the light you are seeing from the sun is 8.3 minutes old -- or rather left the surface of the sun 8.3 minutes ago. Light / Radiant energy / Gravity travels at 300,000 KM per second or roughly 186,000 miles / sec.

say: you do not feel it right away and only a tiny part
-
Valentina say: because the sun is 9,941°F/5,505°C...its very hot.

♘ Vader say: It takes a photon 8 minutes from the surface of the Sun to reach Earth. But it can take up to a million years for the same photon to reach the surface of the Sun from its core.

Gary B say: We DON'T feel the heat "right away". That isd why temperature GRADUALLY warm up from cold at dawn to hot in the middle of teh day.
