NGC 4027 (also known as Arp 22) is a barred spiral galaxy approximately 83 million light-years away 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.
NGC 4027 is part of the NGC 4038 Group, a group of galaxies that also contains the Antennae Galaxies (NGC 4038/NGC 4039).
