Epsilon Trianguli, Latinized from ε Trianguli, is a binary star system in the northern constellation of Triangulum. Based upon measurement of its trigonometric parallax, it is approximately 390 light years from Earth. An excess emission of infrared radiation suggests the presence of a dusty disk in orbit about the primary. This disk has a mean radius of 105 AU, or 105 times the separation of the Earth from the Sun, and is radiating at a temperature of 85 K.

  • Epsilon Trianguli (3 Trianguli) é uma estrela binária na direção da constelação de Triangulum. Possui uma ascensão reta de 02h 02m 57.97s e uma declinação de +33° 17′ 02.9″. Sua magnitude aparente é igual a 5.50. Considerando sua distância de 370 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.22. Pertence à classe espectral A2V. (pt)
  • Epsilon Trianguli (ε Tri, förkortat Epsilon Tri, ε Tri) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den mellersta delen av stjärnbilden Triangeln. Den har en skenbar magnitud på 5,50 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 8,3 mas, beräknas den befinna sig på ett avstånd på ca 390 ljusår (ca 120 parsek) från solen. Stjärnparet ingår sannolikt i rörelsegruppen Ursa Major, bestående av stjärnor som har en gemensam rörelse genom rymden. (sv)
  • 三角座ε(ε Tri、ε Trianguli、天大将军增五)是一個位于三角座的雙星系統,大約距離地球370光年。 其主星三角座εA,是一顆白色的A型主序帶矮星,視星等為+5.50。其伴星三角座εB視星等為+11,距離主星4角秒。 (zh)

  • Эпсилон Треугольника (англ. ε Trianguli) — двойная звезда в созвездии Треугольника. На основе измерения тригонометрического параллакса была получена оценка расстояния от Солнца до звезды 390 световых лет. Избыток инфракрасного излучения означает наличие остаточного диска вокруг главного компонента. Средний радиус диска равен 105 а.е., температура излучения равна 85 K. Звёздная система, вероятно, входит в состав движущейся группы звёзд Большой Медведицы, обладающих сходным движением. Пространственная скорость Эпсилона Треугольника имеет компоненты [U, V, W] = [+11.8, +11.4, –3.8] км/с. (ru)
