IC 1182

IC 1182

IC 1182 is a lenticular galaxy in the constellation Hercules about 474 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. It is receding from us at about 10,209 km/s.

Because its light is 474 million ly from home, you are seeing IC 1182 as it looked roughly 474 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.
