Is the Sun 8 minutes in the future?
Remember, the Earth follows an elliptical orbit around the Sun, ranging from 147 million to 152 million km. At its closest point, sunlight only takes 490 seconds to reach Earth. And then at the most distant point, it takes 507 seconds for sunlight to make the journey. The Sun is more than 8 light-minutes away.
Does the Sun set before we see it?
Sunrise is defined as the moment that the Sun first appears over the horizon. So, by definition, you can’t see the Sun before it appears. But you’re right that we can see the Sun even when it is *geometrically* just below the horizon, at both sunrise and sunset.
How long ago is the Sun we see?
The sunlight we see is 170 000 years and 8.5 minutes old.
Does the sun move every 8 minutes?
Yes, it takes light 8 minute to reach from surface of sun to earth. However, light produced in the core of the sun takes thousands to millions of years to get to the surface.
What can happen in 8 minutes?
27 things you can do in 8 minutes and 46 seconds.

- You can hard-boil an egg.
Can you still see the sun after it sets?
Refraction at Sunrise and Sunset Atmospheric refraction makes the Sun visible even when it is just below the horizon. Because of refraction, the Sun may be seen for several minutes before it actually rises in the morning and after it sets in the evening.
Is the sun still?
But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the birth of our solar system, about 4.5 billion years ago. That’s when the sun will become a red giant. For about a billion years, the sun will burn as a red giant.
Is it possible to reach sun?
In theory, we could. But the trip is long — the sun is 93 million miles (about 150 million kilometers) away — and we don’t have the technology to safely get astronauts to the sun and back yet. The sun would melt anything that got near it. But we can send robotic probes toward the sun and even around it.
How long does it take to see the sunset from Earth?
Another way. A simpler way of putting it is that when you see the sunset you are indeed looking at the Sun’s light from 8 minutes ago. During that 8 minutes the Sun moves 0.0055 degrees to the East due to Earth’s orbit. It takes 1.32 seconds for the Earth to rotate 0.0055 degrees.
Do we only see the Sun 8 minutes in the past?
Yes, you are right. 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 long does it take for the sun to rotate?
A simpler way of putting it is that when you see the sunset you are indeed looking at the Sun’s light from 8 minutes ago. During that 8 minutes the Sun moves 0.0055 degrees to the East due to Earth’s orbit. It takes 1.32 seconds for the Earth to rotate 0.0055 degrees.
How old are photons from the Sun that reach our eyes?
$\\begingroup$If we want to get even more complex, the photons from our sun that reach our eyes are actually much, much older than ~8 mins. They were created at the core of the sun something like 100,000 YEARS ago (I can’t remember the exact estimate–someone pls correct me).
