NGC 262 (also known as Markarian 348) is a huge 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.

This galaxy has an apparent diameter of approximately 1.3 million light-years, occupying 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.
