IC 2112

IC 2112 is a galaxy in the constellation Orion about 499 million ly from Earth. It spans roughly 46,000 ly, about 46% of our Milky Way's width. It is receding from us at about 10,710 km/s.

Because its light is 499 million ly from home, you are seeing IC 2112 as it looked roughly 499 million years ago. The photons left before that much of history had passed, and are only now reaching us. This distance is estimated from the galaxy's redshift, so the lookback time is approximate.
