MCG 7-7-19,
UGC 2515,
CGCG 540-32 |
NGC 1175,[1] also known as the Peanut Galaxy,[2] is a large lenticular galaxy located in the constellation Perseus. Its speed relative to the cosmic microwave background is 5,349 ± 19 km/s, which corresponds to a Hubble distance of 78.9 ± 5.5 Mpc (∼257 million ly).[3] It was discovered by the German-British astronomer William Herschel in 1786.[4]
NGC 1175 is about the same distance from the Milky Way as NGC 1177. These two galaxies form a gravitationally interacting pair.[3]
To date, a non-redshift measurement gives a distance of approximately 44,900 Mpc (∼146 million ly).[5] This value is far outside the Hubble distance values. Note that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy.[3]
