Sunlight arrives
eight minutes late.
The sunlight reaching Earth right now left the Sun’s surface about eight minutes and twenty seconds ago.
SUN8 min 20 secEARTH
Light travels at roughly 300,000 kilometres a second. The Sun is about 150 million kilometres away. Divide the distance by the speed and you get roughly 500 seconds.
So even an ordinary patch of sunlight has spent a little over eight minutes travelling through space before reaching you.
See you tomorrow,
