# How long does Sun Rays take to reach Earth?

## How long does Sun Rays take to reach Earth?

The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us.

## How does radiant energy reach the Earth?

Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth’s surface is in two forms, visible and infrared light. This transfer of energy can take place by three processes: radiation, conduction, and convection.

Do we see the Sun 8 minutes later?

We don’t only see the Sun 8 minutes in the past, we actually see the past of everything in space. We even see our closest companion, the Moon, 1 second in the past. The further an object is from us the longer its light takes to reach us since the speed of light is finite and distance in space are really big.

### How does sunlight travel to Earth?

The Sun’s energy gets to the Earth through radiation, which you can prove just by standing outside and letting the sun’s rays warm your face on a sunny day. The energy lost is emitted as light or electromagnetic radiation. Energy that is absorbed by an atom causes its electrons to “jump” up to higher energy levels.

### How long does it take for sunlight to reach the Earth?

How much time does it take for sunlight to reach the Earth? The speed of light is about 186,000 miles (300,000 kilometers) per second, and the Sun is about 92.58 million miles (149 million kilometers) away, so it takes sunlight 8.4 minutes to reach our planet.

How far back in time is the Sun?

As you look outward into space, you’re actually looking backwards in time. The light you see from your computer is nanoseconds old. The light reflected from the surface of the Moon takes only a second to reach Earth. The Sun is more than 8 light-minutes away.

#### How fast does light travel from the sun to the planets?

How fast does light travel from the Sun to each of the planets? Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit. below I list the light travel times from the Sun to each planet:

#### How many Earths could fit inside the Sun?

The sun’s radius is about 100 times that of the Earth, meaning that about 1.12 million Earths could fit inside it, as could about 930 Jupiter’s. If it takes just over 8 minutes for the Sun’s light to reach Earth, then if the sun were to suddenly extinguish, would we not know it until just over 8 minutes later?
