UGC 4457

Galaxy in the constellation Cancer

UGC 4457 known as PGC 23935, is a barred spiral galaxy, containing an active galactic nucleus in the Cancer constellation.[1][2][3] It is located 500 million light-years away from the solar system[3] and has a diameter of 290,000 light-years,[1] making it slightly more massive compared to the Milky Way.[4] The galaxy is moving away at a speed of 11,162 kilometers per second.[1]

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.[5] 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.[6]
