NGC 3172

Polarissima Borealis (NGC 3172) is a spiral galaxy in the constellation Ursa Minor, which is the closest NGC object to the North Celestial Pole. Because of its proximity – less than 1 degree from that most northerly declination – it received the name Polarissima Borealis. Seeing NGC 3172 is a challenge for an observer with a 12-inch telescope.
