UGC 4457 PGC 23935, Arp 58, IRAS 08290+1922, MCG +03-22-017, VV 413, LEDA 23935,
Z 89-40
UGC 4457 known as PGC 23935, is a barred spiral galaxy, containing an active galactic nucleus in the Cancer constellation. It is located 500 million light-years away from the Solar System and has a diameter of 290,000 light-years, making it slightly more massive compared to the Milky Way. The galaxy is moving away at a speed of 11,162 kilometers per second.
UGC 4457 is interacting with the compact galaxy, PGC 23937. Together, they form Arp 58 and are classified under spiral galaxies that have small companions with high surface brightness. In addition, this interacting galaxy pair is also an M51 type system.
UGC 4457 shows disturbed spiral arms, indicating signs of velocity disturbance levels and regions of scattered ionized gas, typically normal for interacting galaxies. A faint spiral bridge can be seen thus representing the remains of an older mode of spiral waves.
