NGC 488 is a face-on spiral galaxy in the constellation Pisces. It was discovered by German-British astronomer William Herschel on 13 December 1784. It is at a distance of about 90 million light-years away from Earth.NGC 488 Galaxy Galaxies and Clusters of Galaxies, Isaac Newton Group of Telescopes Its diameter is estimated to be ~185,800 Light Years (~52.7 Kpc). The galaxy has a large central bulge, and is considered a prototype galaxy with multiple spiral arms. Its arms are tightly wound. Star forming activity has been traced within the arms.Sandage, A., Bedke, J. (1994), The Carnegie Atlas of Galaxies. Volume I, Carnegie Institution of Washington, p. 15 The nucleus of NGC 488 has been found to be chemically decoupled, being twice as metal rich as the central bulge of the galaxy.
NGC 488 Group NGC 488, with the exception of its smaller companions, form the NGC 488 group; a relatively isolated galaxy group.
NGC 488 is part of a galaxy group known as NGC 488 Group or LGG 21. It has at least 7 members, which are NGC 488, NGC 485, NGC 490, UGC 942, UGC 882, UGC 871 and UGC 888.
