VV Corvi (abbreviated as VV Crv) is a close spectroscopic binary in the constellation Corvus. It is also an eclipsing binary, varying from magnitude 5.19 to 5.34 over 3.145 days. The two stars orbit each other with a period of 1.46 days and an eccentricity of 0.088. The mass ratio of the two stars is 0.775±0.024. The primary is 1.978 ± 0.010 times as massive as the Sun, 18.253 ± 2.249 its luminosity and has 3.375 ± 0.010 the Sun's radius. The secondary is 1.513 ± 0.008 times as massive as the Sun, 4.745 ± 0.583 its luminosity and has 1.650 ± 0.008 the Sun's radius. Both are yellow-white main sequence stars of spectral type F5V, though the primary has begun expanding and cooling as it nears the end of its time on the main sequence. A tertiary companion was discovered during the Two Micron A

  • VV Corvi (abrégé comme VV Crv) est une étoile binaire de cinquième magnitude de la constellation du Corbeau. D'après la mesure de sa parallaxe annuelle par le satellite Gaia, elle est distante de ∼266 a.l. (∼81,6 pc) de la Terre. Le système se rapproche du Système solaire à une vitesse radiale de −14 km/s.

  • からす座VV星（英語: VV Corvi)は、からす座にある近接した分光連星である。2つの恒星は、周期1.46日、軌道離心率0.088で互いの周りを回っている。2つの恒星の質量比は、0.775±0.024である。2008年、2MASSによる観測よって、約5.2度離れた位置にあるF型主系列星が、この連星系の一員であることが判明した。 (ja)

  • VV del Corb (VV Corvi) és un sistema estel·lar de magnitud aparent mitjana +5,27 situat a la constel·lació del Corb. En primera instància, VV del Corb pot ser resolt en dos estrelles, HD 110317 i HD 110318, separades 5,35 segons d'arc. Cadascuna d'elles és, al mateix temps, una estrella binària espectroscòpica. El projecte 2MASS va permetre descobrir la presència d'una distant component, (Ross 702), també associada al sistema. De magnitud +10,5, visualment està a gairebé un minut d'arc. Té una massa de 0,48 masses solars i el seu període orbital supera els 155.000 anys. (ca)
