IC 4745
IC 4745 is a spiral galaxy in the constellation Pavo about 222 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. It is receding from us at about 4,730 km/s.

Because its light is 222 million ly from home, you are seeing IC 4745 as it looked roughly 222 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.
