33 Arietis (abbreviated 33 Ari) is a binary star in the northern constellation of Aries. 33 Arietis is the Flamsteed designation. The combined apparent magnitude of 5.33 is bright enough to be seen with the naked eye. Based upon an annual parallax shift of 14.09 mas, the distance to this system is approximately 231 light-years (71 parsecs).
The primary component is an A-type main sequence star with a magnitude of 5.40 and a stellar classification of A3 V. It has a magnitude 8.40 companion at an angular separation of 28.6 arcseconds. An excess of infrared emission suggests the presence of circumstellar dust in this system. In the 24μm band, this debris disk has a mean temperature of 815 K, which puts it at a radius of 0.85 astronomical units (AU) from the primary star. Excess emission appears in the 70μm band, which has a temperature of 103 K and a radius out to 42 AU.
This star was located in the constellation Musca Borealis.
