3 Piscis Austrini, also known as HD 201901, is a suspected astrometric binary star system that, despite its Flamsteed designation, is actually located in the constellation Microscopium. It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 5.41. The system is moving closer to the Earth with a heliocentric radial velocity of −46 km/s. It is following a highly elliptical orbit around the Galactic Center, moving between a pericenter of 2.6 kpc out to an apocenter of 7.6 kpc, with an orbital eccentricity of 0.49.

  • 3 Piscis Austrini, som är stjärnans Flamsteed-beteckning, eller HD 201901, är en misstänkt astrometrisk dubbelstjärna, belägen i den södra delen av stjärnbilden Mikroskopet trots dess Flamsteedbeteckning. Den har en skenbar magnitud av ca 5,41 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 10,7 mas, beräknas den befinna sig på ett avstånd på ca 310 ljusår (ca 94 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -46 km/s. Stjärnan följer en mycket elliptisk bana runt Vintergatans centrum, som löper mellan ett pericenter av 2,6 kpc ut till ett apocenter av 7,6 kpc, med en excentricitet av 0,49. (sv)

  • 3 Piscis Austrini, also known as HD 201901, is a suspected astrometric binary star system that, despite its Flamsteed designation, is actually located in the constellation Microscopium. It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 5.41. The system is moving closer to the Earth with a heliocentric radial velocity of −46 km/s. It is following a highly elliptical orbit around the Galactic Center, moving between a pericenter of 2.6 kpc out to an apocenter of 7.6 kpc, with an orbital eccentricity of 0.49. The visible component is an evolved giant star with a stellar classification of K3 III. The interferometry-measured angular diameter of the star, after correcting for limb darkening, is 2.03±0.04 mas, which, at its estimated distance, equates to a physical radius of about 20 times the radius of the Sun. It is radiating 174 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,050 K. (en)
