HD 113766 B
The star system was first identified as being potentially interesting by Backman et al. using observations made by the Infrared Astronomical Satellite (IRAS) in 1983. Later measurements in 2001 by a team led by Meyer et al. determined that the system was actually a close binary, with the second star in the system, HD 113766 B, a near twin of HD 113766 A orbiting approximately 170 AU from the A star where the terrestrial planet is forming. Located at more than 4 times the distance of Pluto from our own Sun, HD 113766 B has almost no effect on the material orbiting close to HD 113766 A.
