NGC 5400

NGC 5400 is an elliptical galaxy in the constellation Virgo about 347 million ly from Earth. It spans roughly 140,000 ly, about the width of our Milky Way. It is receding from us at about 7,437 km/s.

Because its light is 347 million ly from home, you are seeing NGC 5400 as it looked roughly 347 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.
