NGC 125 (also known as PGC 1772) is a lenticular galaxy located in the constellation Pisces. It is designated as subclass Sa Ring in the galaxy morphological classification scheme. It lies approximately 235 million light-years away.[4][2][3]
NGC 125 was discovered by astronomer William Herschel on 25 December 1790 and viewed with a reflecting telescope with an aperture of 18.7 inches. At the time of discovery, its coordinates were recorded as 00h 21m 41s, +87° 56.1′ -20.0″. It was also observed 12 October 1827 by John Herschel.[3] Dreyer[which?] described NGC 125 as "very faint" and "small", with a "brighter middle". It is about 115 thousand light-years across, making it slightly larger than the Milky Way galaxy.[4]
