HD 127726

Binary star system in the constellation Boötes

Binary star system in the constellation Boötes

| r-i = | v-r = | b-v = +0.21 | u-b = +0.08 HD 127726 is a binary star system in the northern constellation of Boötes. The pair consist of a rapidly-rotating A-type main-sequence star and a fainter F-type companion, orbiting each other with a period of 29.93 years and an orbital eccentricity (ovalness) of 0.16. They have a combined apparent visual magnitude of 5.88, which is bright enough to be dimly visible to the naked eye. The system is located at a distance of approximately 240 light years from the Sun.

A third star, 4.26" from HD 127726 and magnitude 6.0, shares a common proper motion although any orbit would be thousands of years long.
