IC 442

IC 442 is a lenticular galaxy in the constellation Camelopardalis about 199 million ly from Earth. It spans roughly 72,000 ly, about 72% of our Milky Way's width. It is receding from us at about 4,474 km/s.

Because its light is 199 million ly from home, you are seeing IC 442 as it looked roughly 199 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.
