IC 1813

IC 1813

IC 1813 is a lenticular galaxy in the constellation Fornax about 211 million ly from Earth. It spans roughly 69,000 ly, about 69% of our Milky Way's width. It is receding from us at about 4,453 km/s.

Because its light is 211 million ly from home, you are seeing IC 1813 as it looked roughly 211 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.
