NGC 2402 NED02

NGC 2402 NED02 is a galaxy in the constellation Canis Minor about 244 million ly from Earth. It spans roughly 64,000 ly, about 64% of our Milky Way's width. The light reaching us tonight left it about 244 million years ago.

Because its light is 244 million ly from home, you are seeing NGC 2402 NED02 as it looked roughly 244 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.
