IC 4682

IC 4682

IC 4682 is a barred spiral galaxy in the constellation Pavo about 168 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 5,250 km/s.

Because its light is 168 million ly from home, you are seeing IC 4682 as it looked roughly 168 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.
