41 Arietis (abbreviated 41 Ari) is a triple star system in the northern constellation of Aries. With an apparent visual magnitude of 3.63,[2] this system is readily visible to the naked eye. It has an annual parallax shift of 19.69 mas,[1] which indicates it is at a distance of 166 light-years (51 parsecs) from the Sun.

The system consists of a binary pair,[9] designated 41 Arietis A, together with a third companion star, 41 Arietis D. (41 Arietis B and C form optical pairs with A, but are not physically related.[10]) The components of A are themselves designated 41 Arietis Aa (formally named Bharani /ˈbærəni/)[11] and Ab.
