35 Arietis (abbreviated35 Ari) is abinary star[11] in the northernconstellation ofAries.35 Arietis is theFlamsteed designation. It is approximately 340light-years (100parsecs) distant from the Earth, based upon an annualparallax shift of 9.51 mas.[1] This star is visible to the naked eye with anapparent visual magnitude of 4.64.[2]

This is a single-linedspectroscopic binary system, with the presence of a companion being demonstrated by shifts in the spectrum of the primary component.[12] The pair orbit each other with aperiod of 490.0 days and aneccentricity of 0.14.[11] The primary is aB-type main-sequence star with astellar classification of B3 V.[3] With a mass around 5.7 times that of the Sun, it is radiating 870[8] times the Sun's luminosity. This energy is being emitted from theouter atmosphere at aneffective temperature of 17,520 K,[9] causing it to shine with the blue-white hue of aB-type star.[13]

This star was formerly located in the obsolete constellationMusca Borealis, also known as Lilium.[14]
