NGC 3995 is a Magellanic spiral galaxy in the constellation Ursa Major.

The galaxy lies about 100 million light years away from Earth based on the Tully–Fisher relation, which means, given its apparent dimensions, that NGC 3995 is approximately 80,000 light years across, while based on redshift it lies 170 million light years away.

[7] The nucleus of the galaxy has emission that resembles an HII region.

[8] The spectrum of the galaxy has Wolf-Rayet features, indicative of recent star formation.

[9] Hubble Space Telescope detected 46 star formation knots in the galaxy, most of them having ages less than 20 million years.
