Rho Draconis (ρ Draconis) is a solitary star in the northern circumpolar constellation of Draco. It is faintly visible to the naked eye with an apparent visual magnitude of 4.52. Based upon an annual parallax shift of 7.61 mas as measured from Earth, it is located around 429 light years from the Sun. At that distance, the visual magnitude of the star is diminished by an extinction factor of 0.027 due to interstellar dust.

  • Rho Draconis (ρ Draconis / ρ Dra) est une étoile géante de la constellation circumpolaire boréale du Dragon. Elle est visible à l’œil nu avec une magnitude apparente de 4,52. L'étoile présente une parallaxe annuelle de 7,61 mas mesurée par le satellite Hipparcos, ce qui signifie qu'elle est distante de ∼429 a.l. (∼132 pc) de la Terre. À cette distance, sa magnitude visuelle est diminuée de 0,027 en raison du facteur d'extinction créé par la poussière interstellaire présente sur le trajet de sa lumière jusqu'à la Terre. L'étoile se rapproche du Soleil avec une vitesse radiale de −9,7 km/s. (fr)

  • Rho Draconis (ρ Draconis, förkortat Rho Dra, ρ Dra) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i östra delen av stjärnbilden Draken. Den har en skenbar magnitud på 4,52 och är svagt synlig för blotta ögat. Med stjärnans beräknade avstånd minskar den skenbara magnituden med 0,027 genom skymning orsakad av mellanliggande stoft. Baserat på parallaxmätning inom Hipparcosuppdraget på 7,6 mas, beräknas den befinna sig på ett avstånd av 429 ljusår (131 parsek) från solen. (sv)
