NGC 3315

NGC 3315

NGC 3315 is an elliptical galaxy in the constellation Hydra about 177 million ly from Earth. It spans roughly 62,000 ly, about 62% of our Milky Way's width. It is receding from us at about 3,840 km/s.

Because its light is 177 million ly from home, you are seeing NGC 3315 as it looked roughly 177 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.
