Template:Short description Template:Infobox Galaxy

NGC 4027 (also known as Arp 22) is a barred spiral galaxy approximately 83 million light-years away[1] in the constellation Corvus. It is also a peculiar galaxy because one of its spiral arms goes out more than the other. This is probably due to a galactic collision in NGC 4027's past.

One supernova has been observed in NGC 4027: SN 1996W (type II, mag. 16) was discovered by the BAO Supernova Survey on 10 April 1996.[2][3]
