NGC 7475 NED02

NGC 7475 NED02 is a galaxy in the constellation Pegasus about 516 million ly from Earth. It spans roughly 67,000 ly, about 67% of our Milky Way's width. The light reaching us tonight left it about 516 million years ago.

Because its light is 516 million ly from home, you are seeing NGC 7475 NED02 as it looked roughly 516 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.
