NGC 456 is a nebula with an open cluster located in the constellationTucana.[2] It was discovered on August 1, 1826, by James Dunlop. It was described by Dreyer as "pretty faint, pretty large, irregularly round, mottled but not resolved, 1st of several."[3]
The nebula of NGC 456 is also known as LHA 115-N 83 and often referred as just N83.[1][4] N83 is located next to N84 (NGC 460) and together they form a molecular cloud complex. N83/N84 is an isolated star-forming region in the southeast part of the Small Magellanic Cloud. The region contains a possible supernova remnant.[5] The N83C region was studied with ALMA. The researchers found peaks associated with young stellar objects. The molecular gas is located at the edges of the HII region.[4]
