IC 2498

IC 2498

IC 2498 is a barred spiral galaxy in the constellation Leo about 462 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. It is receding from us at about 9,873 km/s.

Because its light is 462 million ly from home, you are seeing IC 2498 as it looked roughly 462 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.
