NGC 7075 is an elliptical galaxy located about 290 million light-years away[2] in the constellation of Grus.[3] NGC 7075 was discovered by astronomer John Herschel on September 4, 1834.[4] It is classfied a radio galaxy.[5]

NGC 7075 contains a Fanaroff-Riley class I radio source called PKS 2128-388. It has an unresolved core component. Its eastern radio jet, is found to have faint emission which extends out by ≈1.9 kpc from its nucleus.[6] A CO disc is found in NGC 7075 but unresolved. According to Atacama Large Millimeter Array observations, a hole is present in the gas distribution, indicating gas disc disturbance.

IC 5105 Group

According to A. M. Garcia, NGC 7075 is part of the IC 5105 group (also known as LGG 445). This group of galaxies contains at least 19 members. The other galaxies in the group are: NGC 7057, NGC 7060, NGC 7072, NGC 7087, NGC 7110, NGC 7130, IC 5105, IC 5105A, IC 5128, IC 5139, and eight galaxies in the ESO catalogue.[7]
