35 Arietis

Star in the constellation Aries

35 Arietis (abbreviated 35 Ari) is a binary star[11] in the northern constellation of Aries. 35 Arietis is the Flamsteed designation. It is approximately 340 light-years (100 parsecs) distant from the Earth, based upon an annual parallax shift of 9.51 mas.[1] This star is visible to the naked eye with an apparent visual magnitude of 4.64.[2]

This is a single-lined spectroscopic 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 a period of 490.0 days and an eccentricity of 0.14.[11] The primary is a B-type main-sequence star with a stellar 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 the outer atmosphere at an effective temperature of 17,520 K,[9] causing it to shine with the blue-white hue of a B-type star.[13]

This star was formerly located in the obsolete constellation Musca Borealis.
