NGC 71 is an Elliptical galaxy (or possibly a Lenticular galaxy) in the constellation Andromeda. It is in the NGC 68 group. The galaxy was discovered by R. J. Mitchell in 1855, and observed in 1865 by Heinrich d'Arrest, who described it as "extremely faint, very small, round".^[3] The galaxy is about 110,000-130,000 light years across, making it just slightly larger than the Milky Way. The galaxy is the second largest in the NGC 68 group, after spiral galaxy NGC 70.
