The distance light must travel is the distance from Sun to Earth - about 150 million km.
No. 150 million km is the distance from Earth to Sun, and this distance is called an AU (astronomical unit). Light travels this distance in about 8 minutes.A light-year is the distance traveled by light in a year, which of course is much more than the distance traveled in 8 minutes. A light-year is approximately 9.461 x 10 to the power 12 km.
The farthest light has traveled is 13.8 billion light years from Earth, which is the observable edge of the observable universe.
Andromeda galaxy is 1,974,973,990 light years from earth, source N.A.S.A. the second furthest star from Earth is 1,974,973,990 light years away..... ----------------------------- There are 5,878,499,814,186.5 miles traveled in a light year, (thats 5.8+ Trillion miles) the center of Andromeda is approx. 2.5 million light years away. The math is beyond me. If 2 steam engines leave their stations from earth 15 minutes apart when will they end up in Andromeda?????
The distance from the Earth to the Sun is approximately 93 million miles (about 150 million kilometers). At the speed of light, it would take light 500 seconds to travel this distance. This is because light travels at a speed of about 186,282 miles per second or 299,792 kilometers per second.
Messier 101 (M101) is a galaxy located around 21 million light-years away from Earth.
10,700 million light-years.
About 2.5 million light-years.Approximately 2.5 million light years away
That would only be possible if we could travel faster than the speed of light...a lot faster...and then you would have to get farther out than light from earth has traveled in the last million years and then look toward earth..then, in theory, you could see the past.
13,100 million light-years.
1000 million light-years.
12,900 million light-years.
5300 million light-years.
