IC 2009

IC 2009

IC 2009 is an irregular galaxy in the constellation Horologium about 74 million ly from Earth. It spans roughly 32,000 ly, about 32% of our Milky Way's width. It is receding from us at about 1,584 km/s.

Because its light is 74 million ly from home, you are seeing IC 2009 as it looked roughly 74 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.
