NGC 262 (also known as Markarian 348) is a spiral galaxy in the cluster LGG 14.^[1] It is a Seyfert 2 spiral galaxy located 287 million light years away in the constellation Andromeda.^[2] It was discovered on September 17, 1885 by Lewis A. Swift.

Size

This galaxy has an apparent diameter of 1.1' of the Earth's sky.^[3] It holds approximately 15 trillion stars.^{[citation needed]} [NGC 262] was tidally disturbed by the gravitational forces of smaller galaxies, which resulted in its large size.^[3]

NGC 262 is very unusual, since it is 10 times larger than a regular spiral galaxy of its type.^[2] According to Morris and Wannier, NGC 262 is surrounded by a huge cloud of neutral hydrogen^[2] that is probably caused by the tidal stripping of smaller galaxies. The cloud has an apparent mass of approximately 50 billion solar masses^[2] at a distance of 88 kiloparsecs (287,000 light-years)^[2] from the nucleus of NGC 262 and extending up to 300 kiloparsecs (1 million light-years) away.^[2] The cloud is spiral shaped with at least one arm, and possibly another one extending throughout the galaxy.
