It depends where the light source is.
1051 miles away 1255 km
Approxiamtely 4.3 light years away
No. If you look far enough away, you will see OTHER objects in the past. For example, if a galaxy is ten million light-years away, the light of this galaxy took 10 million years to reach us, so we see this galaxy 10 million years ago. Earth's light, from millions of years ago, doesn't come back to us, since (roughly speaking) light travels in a straight line, and moves at the speed of light (300,000 km/sec).
The sun is not light years away but light minutes and the sun is 8 (rounded) light minutes away from us. But if you really want to know how far away the sun is from us in light years it is 0.000015 of a light year away from us.
The farthest star from Earth is currently believed to be Icarus, which is located about 9 billion light years away. This star was observed using the Hubble Space Telescope in 2018. It is so far away that its light took about 9 billion years to reach us.
Territorial waters extend 22.2 km away from the coast, but the exclusive economic zone extends 370.8 km.
A light year is a measure of how far light can travel in one year. It is a phenomenal distance, and is used to describe how far away stars are from us.
2 km
Quasars can be very, very, very far away. And they are extremely bright. We've seen quasars that are 12 billion light years away from Earth (a light year is how far light travels in one year, and light travels at about 128 billion kilometers a second). Most quasars are actually big, bright galaxies shining from millions, or even billions of light years away from here.
Betelgeuse is a red supergiant in the constellation Orion. It is approximately 640 light years from us.
Algieba is about 90 light years away from us
12.5 light years away :) 73487500000000 miles 118259130907260 kilometers that is the nearest galaxy but the nearest sun is Alpha centauri; it is 44000 Billion km away from earth
