NGC 750 is an elliptical galaxy approximately 225 million light-years away from Earth in the constellation of Triangulum.

[3] German-born British astronomer William Herschel was first to discover a galaxy at this location on September 12, 1784, but he did not resolve this close pair, therefore he described it as a single object NGC 750.

[3] At least 100,000,000 years have passed since the moment of the first strong tidal perturbation between these two galaxies.

[5] While NGC 750 exhibits nearly flat radial velocity curves, the radial velocity curves of NGC 751 are characterized by large variations of more than 100 km s−1 along the slit.

[5] A large, diffuse tidal tail extends 20 arcsec (10 kpc) to the north-east of the pair.
