29 Arietis is a triple star system in the northern constellation of Aries. 29 Arietis is the Flamsteed designation. Its annual parallax shift of {{val|34.86|0.13|ul=mas}} indicates a distance of about {{Convert|94|ly|pc|abbr=off|lk=on}} 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. It is moving further from Earth with a heliocentric radial velocity of 9 km/s.

The core of the system is formed by a close spectroscopic binary with an angular separation of 3.892 mas, a semimajor axis of {{Val|0.15692|0.00086|ul=AU}}, an orbital period of 19.4 days, and an eccentricity of 0.4. 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.
