NGC 4045

NGC 4045

NGC 4045 is a spiral galaxy in the constellation Virgo about 92 million ly from Earth. It spans roughly 69,000 ly, about 69% of our Milky Way's width. It is receding from us at about 1,948 km/s.

Because its light is 92 million ly from home, you are seeing NGC 4045 as it looked roughly 92 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.
