HD 35184 is a solitary star in the southern circumpolar constellation Mensa. It has an apparent magnitude of 6.50, which the maximum naked eye visibility. Located 375 light years away, it is receding with a heliocentric radial velocity of 13.6 km/s.

HD 35184 has a stellar classification of A6 V, indicating that it is an ordinary A-type main-sequence star. At present it has 2.15 times the mass of the Sun[6] and 2.8 times the radius of the Sun.[7] It shines at 24.5 L☉ from its photosphere at an effective temperature of 8,034 K,[8] giving it a white hue. HD 35184 is 674 million years old – 79.6% through its main sequence lifetime[6] – and spins with a projected rotational velocity of 92 km/s−1.[10]
