Theta Ursae Minoris, Latinized from θ Ursae Minoris, is a suspected binary star system that is visible to the naked eye in the northern circumpolar constellation of Ursa Minor. It is roughly 860 light years from Earth with an apparent visual magnitude of 5.0. The system is moving closer to the Sun with a radial velocity of −25 km/s. Photometry from the Hipparcos satellite mission shows that θ Ursae Minoris varies in brightness by a few hundredths of a magnitude. It is listed as NSV 20342 in the New Catalogue of Suspected Variable Stars.

  • Theta Ursae Minoris (θ Ursae Minoris, förkortat Theta UMi, θ UMi) som är stjärnans Bayer-beteckning, är en misstänkt dubbelstjärna i den mellersta delen av stjärnbilden Lilla björnen. Den har en skenbar magnitud på +4,98 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätningar i Hipparcos-uppdraget på 3,8 mas beräknas den befinna sig på ca 860 ljusårs (260 parsek) avstånd från solen. (sv)

  • Theta Ursae Minoris (θ Ursae Minoris / θ UMi) est une étoile binaire suspectée de la constellation circumpolaire boréale de la Petite Ourse. Elle est localisée à 716±24 a.l. (∼220 pc) de la Terre et elle est visible à l’œil nu avec une magnitude apparente de 5,0. L'étoile se rapproche du Soleil avec une vitesse radiale de −25 km/s. La photométrie obtenue durant la mission du satellite Hipparcos montre que θ Ursae Minoris varie en luminosité de quelques centièmes de magnitude. Elle a été cataloguée sous la désignation NSV 20342 dans le New Catalogue of Suspected Variable Stars. (fr)
