| dbo:abstract | Xi Telescopii, Latinized from ξ Telescopii, is a solitary star in the southern constellation of Telescopium. It is visible to the naked eye, with an apparent visual magnitude of +4.95. Based upon an annual parallax shift of 3.02 mas as measured from Earth, it is located approximately 1,100 light-years from the Sun. This is an evolved star with a stellar classification of K5 III or M1 IIab, indicating it is a giant or bright giant star. This is a variable star tentatively classified as a slow irregular-type variable with a brightness that varies between magnitude +4.89 and +4.94. Koen and Eyer examined the Hipparcos data for this star, and found that it varied periodically, with a period of 12.36 days, and an amplitude of 0.0083 magnitudes. With around 56 times the Sun's radius, it shines with a luminosity approximately 2,973 times that of the Sun and has a surface temperature of 4,030 K.

(pt) Xi Telescopii (ξ Telescopii, förkortat Xi Tel, ξ Tel) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den nordvästra delen av stjärnbilden Kikaren. Den har en genomsnittlig skenbar magnitud på 4,95 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 3,0 mas, beräknas den befinna sig på ett avstånd på ca 1 100 ljusår (ca 330 parsek) från solen.
