Chi3 Sagittarii (χ3 Sagittarii) is a solitary, [11] orange-hued star in the zodiac constellation of Sagittarius. It is faintly visible to the naked eye with an apparent visual magnitude of +5.45. [2] Based upon an annual parallax shift of 6.53 mas as seen from Earth, [1] it is located roughly 500 light years from the Sun. It is receding from the Earth with a radial velocity of 39.6 km/s. [5]
This is an evolved, K-type giant star with a stellar classification of K3 III. [3] It is a suspected optical variable star with a magnitude range of 5.42 to 5.46. [4] At infrared wavelengths, it shows large amplitude variation with a period of 505 days. [12] The star has expanded to about 37 [7] times the Sun's radius and is radiating 301 [8] times the solar luminosity from its photosphere at an effective temperature of 4,040 K. [9]
