HD 113766 is a binary star system located 424 light years from Earth[1] in the direction of the constellation Centaurus.

HD 113766 represents the most well understood system in a growing class of objects that should provide more clues to how rocky planets like the Earth formed.

The dusty material in the system was analyzed in 2007 by a group led by Dr. Carey Lisse, of the Johns Hopkins University Applied Physics Laboratory in Laurel, MD, USA.

Observations were made using the infrared spectrometer on board the Spitzer Space Telescope, and interpreted using the results of the NASA Deep Impact and STARDUST missions.

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.
