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]
