How far away is the Sun from Earth in light seconds?
How far away is the Sun from Earth in light seconds?
It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.
How long light takes from Sun to Earth?
about 5 and 1/2 hours
Light from the Sun takes about 5 and 1/2 hours to reach it and roughly the same time to return to Earth. By the time the light reaches us, it has spread out so much that the planet looks very dim, and requires a good telescope to spot.

What planet is closest to the sun?
Mercury
Mercury. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.
Which side of the Earth has night?
As the Earth moves around the Sun it rotates on its axis, so we have day and night. The side of the Earth facing the Sun is bathed in light and heat (daytime). The side of the Earth facing away from the Sun, out towards space, is darker and colder (nighttime).
Can humans travel to the sun?
But if you take a look around, there’s nothing here for you to actually land on, because the sun doesn’t have any solid surface to speak of. It’s just a giant ball of hydrogen and helium gas. So instead of landing on the photosphere, you’re going to sink into it.
What is the distance between the Sun and Earth in light years?
What is the distance between the Sun and Earth in light-years? Light travels at 300,000 km/s, and the sun is right about 150,000,000 km away from Earth, so light takes around 500 seconds (8.3 minutes) to reach the Earth’s surface, give or take.
How many minutes does it take light to travel to Earth?
The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
How long does it take sunlight to reach US?
How many miles per second is the speed of light?
Put another way, a light year is how far you’d travel in a year if you could travel at the speed of light, which is 186,000 miles (300,000 kilometers) per second. (By the way, you can’t travel at the speed of light, as far as we know, but that’s a whole other story…)
