UGC 1840, also known as Arp 145, are a pair of interacting galaxies located 250 million light-years away from the Solar System in the Andromeda constellation.[2] The earliest known reference to the pair of galaxies is in part 2 of the Morphological Catalogue of Galaxies, published in 1964, where it is listed as MCG +07-06-002.[3]

Made up of two galaxies, UGC 1840 NED01 (PGC 9060)[4] and UGC 1840 NED02 (PGC 9062),[5] the two galaxies had recently collided with each other[6] in which the elliptical galaxy has penetrated through the spiral galaxy's nucleus leaving a hole in its middle, thus forming a ring galaxy.[7][8] With a diameter of 1.3 arc minutes, close to 100,000 thousand light-years, they are roughly the same size as the Milky Way.[9][unreliable source?]

Both galaxies are listed as Arp 145 in the Atlas of Peculiar Galaxies which was created by Halton Arp.[10][11] They fall under the category of objects that have emanating material and both classified as galaxies that have ring systems.
