NGC 988 is aspiral galaxy located in theconstellationCetus.[4] It lies at a distance of 50 millionlight years from Earth, which, given its apparent dimensions, means that NGC 988 is about 75,000 light years across. The magnitude 7.1starHD 16152 is superposed 52" northwest of the center of NGC 988. The galaxy was discovered byÉdouard Jean-Marie Stephan in 1880.[5] Oneultraluminous X-ray source has been detected in NGC 988.[6]

NGC 988 is the brightest galaxy in NGC 1052 group[7] (also known as NGC 988 group), which includes the galaxiesNGC 991,NGC 1022,NGC 1035,NGC 1042,NGC 1047,NGC 1051,NGC 1052,NGC 1084, andNGC 1110. It belongs in the same galaxy cloud asMessier 77.[8]

Onesupernova has been observed in NGC 988: SN 2017gmr (type II, mag. 15.1187) was discovered by theDistance Less Than 40 Mpc Survey (DLT40) on 4 September 2017.[9]
