NGC 266 is a barred spiral galaxy with an active galactic nucleus from Hubble type SBab in the constellation Andromeda on the northern sky . It is estimated to be 215 million light years from the Milky Way and about 190,000 light years in diameter. Presumably the system is gravitationally bound with NGC 262 . Together with 42 other galaxies, it forms the NGC 315 group .

The object was discovered on September 12, 1784 by the German-British astronomer Wilhelm Herschel .
