Upsilon Draconis (υ Dra) is a binary star system in the northern circumpolar constellation of Draco. It is faintly visible to the naked eye with an apparent visual magnitude of 4.83. Based upon an annual parallax shift of 9.48 mas as measured from Earth, it is located around 340 light years from the Sun. At that distance, the visual magnitude of the star is diminished by an extinction factor of 0.02 due to interstellar dust.

  • Upsilon Draconis (υ Dra / υ Draconis) adalah salah satu bintang pada rasi Draco . Bintang ini memiliki magnitudo 4.82 dan merupakan bintang dengan kelas K0III. Bintang ini berada pada jarak 344 tahun cahaya dari Bumi. (in)
  • Ypsilon Draconis (υ Draconis, förkortat Ypsilon Dra, υ Dra) som är stjärnans Bayerbeteckning, är en spektroskopisk dubbelstjärna, med en omlopsperiod 258,48 dygn och excentricitet på 0,21, belägen i nordöstra delen av stjärnbilden Draken. Den har en skenbar magnitud på 4,83 och är svagt synlig för blotta ögat. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 9,48 mas, beräknas den befinna sig på ett avstånd av ca 340 ljusår (105 parsek) från solen. På det beräknade avståndet minskar stjärnans skenbara magnitud med en skymningsfaktor på 0,02 på grund av mellanliggande stoft. (sv)
