(pt) Ypsilon Coronae Borealis (υ Coronae Borealis, förkortat Ypsilon CrB, υ CrB) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den sydöstra delen av stjärnbilden Norra kronan. Den har en skenbar magnitud på 5,78 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 4,9 mas, beräknas den befinna sig på ett avstånd på ca 670 ljusår (ca 200 parsek) från solen.

Bintang ini bermagnitudo 5.80. (in) Upsilon Coronae Borealis, Latinized from υ Coronae Borealis, is a solitary star in the northern constellation of Corona Borealis. It is a white-hued star that is dimly visible to the naked eye with an apparent visual magnitude of 5.78. The distance to this object is approximately 630 light-years (190 parsecs) based on parallax. This is an A-type main-sequence star with a stellar classification of A3V; a star that is currently fusing its core hydrogen. However, Palmer et al. (1968) had it classed as type A2IV, and thus it may be near or past its main sequence lifetime. It is a suspected variable star of unknown type that has been measured ranging in brightness from magnitude 5.78 down to 5.88. Upsilon Coronae Borealis has three times the mass of the Sun and about 1.5 times the Sun's radius. It is spinning with a projected rotational velocity of 112 km/s. The star is radiating 151 times the luminosity of the Sun from its photosphere at an effective temperature of 8,098 K.
