NGC 7075 is an elliptical galaxy located about 290 million light-years away[2] in the constellation of Grus.[3][4] NGC 7075 was discovered by astronomer John Herschel on September 4, 1834.[3] 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.[7]
