NGC 5685

NGC 5685 is an elliptical galaxy in the constellation Boötes about 484 million ly from Earth. It spans roughly 150,000 ly, about the width of our Milky Way. It is receding from us at about 10,339 km/s.

Because its light is 484 million ly from home, you are seeing NGC 5685 as it looked roughly 484 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.
