NGC 210

NGC 210

NGC 210 is a spiral galaxy in the constellation Cetus about 76 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 1,735 km/s.

Because its light is 76 million ly from home, you are seeing NGC 210 as it looked roughly 76 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.
