NGC 1132 is an elliptical galaxy located in the constellation Eridanus.[4] The galaxy was discovered by John Herschel on November 23, 1827.[5] It is located at a distance of about 318 million light-years away from Earth.[6]

NGC 1132 and nearby small galaxies are known as a "fossil group" that resulted from the merger of a group of galaxies.[4] It is the prototype example of the class of fossil galaxy groups.[7] The identification as a fossil group was made in 1999.[8] This group contains an enormous amount of dark matter and a large amount of hot gas that emits X-ray radiation.[9] The galaxy is surrounded by thousands of globular star clusters.[10]

One supernova has been observed in NGC 1132: SN 2024pbe (type Ia, mag. 17.8).[11]
