How old is the sunlight you see?
Light from the Sun takes 8 minutes 20 seconds to reach Earth. You have never seen the Sun as it is right now.
Source: 1 AU divided by the speed of light.
Context
About 8 minutes 20 seconds. Light covers the distance from the Sun to Earth, one astronomical unit, in that time.
So the Sun you see is the Sun as it was 8 minutes ago. If it vanished, you would keep seeing it, and Earth would keep orbiting it, for those 8 minutes.
This fact sits next to the reaction time test. See where you land.
