Encyclopedic overview
NGC 262 (also known as Markarian 348) is a Seyfert 2 spiral galaxy located 65.4 megaparsecs (213 million light-years) away in the constellation Andromeda. It was discovered on 17 September 1885 by Lewis A. Swift.
NGC 262 was tidally disturbed by the gravitational forces of smaller galaxies, which resulted in a surrounding large cloud over 10 times larger than the Milky Way. It is also a member of the NGC 315 Group (also known as LGG 14), which contains 42 galaxies, including NGC 226, NGC 243, NGC 266, NGC 311, NGC 315, NGC 338, IC 43, IC 66, and IC 69, among others.
