IC 5188

IC 5188 is a spiral galaxy in the constellation Tucana about 217 million ly from Earth. It spans roughly 81,000 ly, about 81% of our Milky Way's width. It is receding from us at about 4,576 km/s.

Because its light is 217 million ly from home, you are seeing IC 5188 as it looked roughly 217 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.
