Psi2 Lupi (ψ2 Lupi, förkortad Psi2 Lup, ψ2 … Psi2 Lupi (ψ2 Lupi, förkortad Psi2 Lup, ψ2 Lup), som är stjärnans Bayer-beteckning, är en trippelstjärna i norra delen av stjärnbilden Vargen. Den har en skenbar magnitud av 4,75 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 9,0 mas, beräknas den befinna sig på ett avstånd av ca 360 ljusår (111 parsek) från solen. På det beräknade avståndet minskar dess skenbara magnitud med 0,016 ± 0009 enheter på grund av interstellärt stoft. Stjärnan ingår i undergruppen Övre Centaurus-Lupus inom Scorpius-Centaurus-föreningen.-Lupus inom Scorpius-Centaurus-föreningen.
, Psi2 Lupi (ψ2 Lup) is a triple star system … Psi2 Lupi (ψ2 Lup) is a triple star system in the constellation Lupus. It is visible to the naked eye with an apparent magnitude of 4.75. Based upon an annual parallax shift of 8.97 mas as seen from Earth, it is located around 360 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.016±0.009 due to interstellar dust. This system is a member of the Upper Centaurus–Lupus subgroup of the Scorpius–Centaurus association. The inner pair of stars in this system form a double-lined spectroscopic binary with an orbital period of 12.26 days and an eccentricity of 0.19. The two components are described as similar in appearance. They have the spectrum of a B-type main sequence star with a stellar classification of B5 V. The luminosity has a micro-variability with a frequency of 0.94483 cycles per day and an amplitude of 0.0067 in magnitude. The third component is a magnitude 10 star at an angular separation of 0.51 arc seconds.an angular separation of 0.51 arc seconds.
