NGC 2857 is the first object in
Halton Arp's Atlas of Peculiar Galaxies, and one of six Arp objects in the 'Low Surface Brightness Galaxies' section. The other five low surface brightness galaxies are Arp 2 (
UGC 10310),
Arp 3,
Arp 4, Arp 5 (
NGC 3664), and Arp 6 (
NGC 2537
NGC 2537, also known as the Bear Paw Galaxy or Bear Claw Galaxy, is a blue compact dwarf galaxy in the constellation Lynx, located around 3 degrees NNW of 31 Lyncis. This is Arp 6 or Mrk 86. It belongs to the iE class of Blue Compact Dwarf (BCD ...
).
On October 10, 2012, supernova SN 2012fg was observed in NGC 2857 by the MASTER-Kislovodsk auto-detection system. Its absolute magnitude was calculated to be -19.8. The spectrum of SN 2012fg was recorded and analyzed by multiple teams of scientists as it changed rapidly in the days following its detection.
