HR 7703 [SEP] constellation
HR 7703
HR 7703 (Gliese 783, 279 G. Sagittarii) is a binary star system in the constellation of Sagittarius. The brighter component has an apparent visual magnitude of 5.31, which means it is visible from suburban skies at night. The two stars are separated by an angle of 7.10″, which corresponds to an estimated semimajor axis of 56.30 AU for their orbit.
Based upon an annual parallax shift of 0.16625 arc seconds as measured by the Hipparcos satellite, this system is from Earth. It is approaching
14 stars within 22 light years with a relatively high probability of having habitable planets (a collective probability of 43%). Writing in a "Scientific American" blog in 2011, Caleb Scharf called it "extraordinarily detailed and prescient".
