How Far Can You See in the Universe?

Impress your friends by telling them how far you can see. Fraser Cain of Universe Today explains what the most distant object in the sky is that can be seen with the naked eye. On the surface of Earth, the horizon usually appears to be about three miles away. But what about those objects we see in the sky? We can see Saturn — the most distant object we can see in the Solar System at 1.5 billion kilometers.

The most distant object we can see is likely to be a supernova or a galaxy cluster. Andromeda is 2.6 million lightyears away and is about as far as we can see without help of a telescope.
