NGC 3172 (also known as Polarissima Borealis [1]) is a lenticular galaxy located in the constellation Ursa Minor. It is the closest NGC object to the north celestial pole. [1] Discovered by John Herschel in 1831, it is about 285 million light-years away and about 85 thousand light-years across. [3]
Two supernovae have been observed in NGC 3172. SN 2010af ( type Ia, mag. 17.2), was discovered on 4 March, 2010. [4] SN 2017gla (type Ia, mag. 16), was discovered on 1 September, 2017. [5]
- NGC 2573 - the closest NGC object to the south celestial pole.
