Theta Chamaeleontis, Latinized from θ Cha, is a single, orange-hued star located in the southern constellation of Chamaeleon. It is a dim star but visible to the naked eye with an apparent magnitude of 4.34. Parallax measurements by the Hipparcos spacecraft put the system at 155 light-years, or 47.6 parsecs away. It is moving away from the Sun with a radial velocity of +22 km/s. It has a visual companion, Theta Chamaeleontis B. This is a magnitude 12.44 star at an angular separation of 21.1 arcseconds from component A along a position angle of 237°, as of 2000.

  • Theta Chamaeleontis (θ Chamaeleontis, förkortat Theta Cha, θ Cha) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den västra delen av stjärnbilden Kameleonten. Den har en skenbar magnitud på 4,34 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 21,0 mas, beräknas den befinna sig på ett avstånd på ca 155 ljusår (ca 48 parsek) från solen. (sv)

  • Тета Хамелеона (лат. θ Chamaeleontis) — одиночная звезда оранжевого цвета в южном приполярном созвездии Хамелеона. Это слабая звезда, но видимая невооружённым глазом, с видимой звёздной величиной 4,34. Измерения годичного параллакса космическим телескопом Hipparcos дали оценку расстояния до звезды 155 световых лет или 47,6 парсеков. Звезда удаляется от Солнца со скоростью +22 км/с. Обладает видимым компонентом Тета Хамелеона B, являющимся объектом видимой звёздной величины 12,44 на расстоянии 21,1 угловой секунды от компонента A при позиционном угле 237° по состоянию на 2000 год.
