Two of the bodies are the stars in the binary system. The third is the planet whose orbit you are trying to compute.

It is not clear that our solar system is definitively not binary. There may be a dark body a couple of times larger than Jupiter out there somewhere. If its orbit relative to the solar system CM is a bit eccentric, then we might not yet have had the opportunity to measure perturbations of planetary orbits influenced by it. Scientific measurements have only been made over about the last 500 years or so. Civilisation exists by geological (and astrophysical) consent, to paraphrase Will Durant.

ScienceDaily is not a science site, but a news and sensationalism site. You will not learn science there, but only get stirred up. They are trying to sell advertising.
