NGC 3994 is an unbarred spiral galaxy in the constellation Ursa Major.

The galaxy lies about 160 million light years away from Earth, which means, given its apparent dimensions, that NGC 3994 is approximately 70,000 light years across.

[4] The triplet is part of the NGC 3966 Group or LGG 259.

[5][6] The nucleus of the galaxy has been found to be active, and based on its spectral lines it is a composite object with LINER and HII region characteristics.

[7] The nucleus lacks central ultraviolet emission when observed by the Hubble Space Telescope.
