NGC 4932 is a 13.7 likes bright spiral galaxy of Hubble type Sc in the constellation Canes Venatici on the northern sky . It is an estimated 321 million light years from the Milky Way and about 140,000 light years in diameter. Presumably it forms a gravitationally bound galaxy pair together with PGC 214058 .
In the same area of the sky is u. a. the galaxy NGC 4938 .
The object was discovered on April 26, 1789 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as "cF, S, R, comparbM".
