The galaxy was discovered by astronomer by Heinrich d'Arrest on September 16, 1865[4] and is a member of Abell 262.[5][6][7][8][9][10] NGC 753 has roughly 2-3 times more mass than the Milky Way[5] and is classified as a radio galaxy.[11][12][13] Physical characteristicsNGC 753 contains two main arms that extend to 180° on either side of the galaxy.[14][15] From the two main arms, there are three larger and weaker arms that sub-divide into several branches.[14] This open structure of the arms may be due to the influence of NGC 759 which is a close companion of NGC 753[14][15] that lies {{convert|0.44|Mpc|Mly|abbr=on|lk=on|order=flip}} away.[15] Supermassive black holeNGC 753 has a supermassive black hole with an estimated mass of (2.2 ± 0.4) × 107 M☉.[16] SupernovaeNGC 753 has hosted two supernovae,[17] SN 1954E which was discovered by Fritz Zwicky[18][19] on September 26, 1954[18][19][17][20] and AT 2018ddf which was discovered on July 5, 2018.[17][21][22] Both supernovae were of unknown types.[17][19][21][20][22] See also
