29 Arietis is a triple star[1] system in the northern constellation of Aries. 29 Arietis is the Flamsteed designation. Its annual parallax shift of Шаблон:Val[2] indicates a distance of about Шаблон:Convert from Earth. The system is barely visible to the naked eye with an apparent visual magnitude of 6.0; it is 0.02 degree north of the ecliptic.[3] It is moving further from Earth with a heliocentric radial velocity of 9 km/s.[3]

The core of the system is formed by a close spectroscopic binary with an angular separation of 3.892 mas,[1] a semimajor axis of Шаблон:Val, an orbital period of 19.4 days, and an eccentricity of 0.4.[4] The larger member of this pair has 114% of the mass of the Sun, while its companion has 88% of the Sun's mass. Orbiting the pair at an angular separation of 1.422 arcseconds over a period of 164 years, the tertiary component has 52% of the Sun's mass.[1]
