NGC 4388 is an active spiral galaxy in the equatorial constellation of Virgo. This galaxy is located at a distance of 57 million light years and is receding with a radial velocity of 2,524km/s. It is one of the brightest galaxies of the Virgo Cluster due to its luminous nucleus. NGC 4388 is located 1.3° to the west of the cluster center, which translates to a projected distance of ≈400 kpc. The NGC 4388 galaxy has been assigned a morphological class of SA(s)b, which indicates it is a spiral with no central bar (SA) or inner ring structure (s), and has moderately-wound spiral arms (b). It is inclined at an angle of 79° to the line of sight from the Earth and thus is being viewed from nearly edge-on. The major axis of the elliptical profile is aligned with a position angle of 92°. It was discovered by German-British astronomer William Herschel on April 17, 1784.
