Zeta Trianguli Australis (ζ TrA) is a spectroscopic binary in the constellation Triangulum Australe. It is approximately 39.5 light years from Earth. The system is composed of two main sequence stars, one a yellow-white F-type dwarf and the other a yellow G-type dwarf. The binary's composite spectral class is F9V and its combined apparent magnitude is +4.90. The pair orbit each other once every 13 days, and the orbital eccentricity is 0.014.

  • Zeta Trianguli Australis (ζ TrA) is a spectroscopic binary in the constellation Triangulum Australe. It is approximately 39.5 light years from Earth. The system is composed of two main sequence stars, one a yellow-white F-type dwarf and the other a yellow G-type dwarf. The binary's composite spectral class is F9V and its combined apparent magnitude is +4.90. The pair orbit each other once every 13 days, and the orbital eccentricity is 0.014. Somewhat surprisingly for a star located at 70° S, it is a swarm member of the Ursa Major moving group.
  • Zeta Trianguli Australis (ζ TrA / HD 147584 / HR 6098)
  • Zeta Trianguli Australis (ζ TrA) est une étoile binaire spectroscopique située à environ 40 années-lumière de la Terre dans la constellation du Triangle austral. La première composante est une naine jaune-blanche de la séquence principale et de type spectral F. Sa luminosité est de 40% supérieure par rapport à celle du Soleil. La deuxième composante est une naine jaune.
  • Zeta Trianguli Australis è una stella di classe spettrale F9-V, distante 39,5 anni luce dal Sistema solare
  • 南三角座ζ（ζ TrA）是位于南三角座的雙星系統，約距離地球39.5光年。 此雙星系統由兩顆主序星組成，一顆為黃白色的F型矮星，另一顆為黃色的G型矮星。兩顆星的結合光譜型為F9V，結合視星等為+4.90。它們互相圍繞著對方公轉，周期為13天，軌道離心率為0.014。 儘管南三角座ζ在夜空中的位置在70° S，它依然屬於大熊座移動星群。
