Click to view the animation demonstrating the orbit of the close binary pair Ba, Bb in the HIP 83716 Triple System. The orbit has been calculated from five observations (blue circles) taken between 2009, when the close binary was discovered at SOAR, and 2014, the date of the most recent observation.
