Is the Sun 7 light minutes away?

What happens if you look at the sun for 20 seconds?

“Staring at the sun even for a few seconds can damage the retina. This condition is called solar retinopathy, and it can happen even if you are watching a solar eclipse.

How far is one light day?

“A light day is an astronomical unit of length. It is defined as the distance light travels in an absolute vacuum in one day (of 86,400 seconds) or 25,902,068,371,200 meters (~26 Tm).”

How do we know light takes 8 minutes?

“TL;DR: Because light doesn’t travel at an infinite speed. Light travels at exactly 299,792,458 meters per second, and one AU is equal to 149,597,870,700 meters. Therefore, it takes about 500 seconds, or 8 minutes and 20 seconds, for light to travel from the Sun to Earth.”

How far is 5 light minutes?

“The distance from earth to the sun is 5 light minutes or 90,000,000 km.”

Why does the Sun take 8 minutes?

“Light travels at a speed of 300,000 kms−1 and the distance between Earth and the sun is 150 million km. Thus it takes nearly 8 minutes for light from the sun to reach Earth.”

How long until we notice the Sun is gone?

“If the sun disappears suddenly, total darkness will be observed on Earth after 8 minutes – the time it take for its light to reach us.”

Does the Earth orbit where the Sun was 8 minutes ago?
