IC 5171

IC 5171 is a spiral galaxy in the constellation Grus about 133 million ly from Earth. It spans roughly 29,000 ly, about 29% of our Milky Way's width. It is receding from us at about 2,693 km/s.

Because its light is 133 million ly from home, you are seeing IC 5171 as it looked roughly 133 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.
