This elliptical galaxy has an extremely long tidal tail and shell structure, seen across several deep-sky surveys, indicating a likely-recent and possibly ongoing interaction with nearby galactic neighbor NGC 364.
^ abAn object's distance from Earth can be determined using Hubble's law: v=Ho is Hubble's constant (70±5 (km/s)/Mpc). The relative uncertainty Δd/d divided by the distance is equal to the sum of the relative uncertainties of the velocity and v=Ho
