Rho3 Arietis (Rho3 Ari, ρ3 Arietis, ρ3 Ari) is the Bayer designation for a star in the northern constellation of Aries. It is faintly visible to the naked eye with an apparent visual magnitude of 5.63.[2] Based upon an annual parallax shift of 28.29 mas,[1] this star is located at a distance of approximately 115 light-years (35 parsecs) from Earth.

This is an astrometric binary system.[7] The visible component is an F-type main sequence star with a stellar classification of F6 V.[3] It is around 2.4 billion years old[4] and has a high abundance of elements other than hydrogen and helium when compared to the Sun.[5]
