Spying on your neighbors can be an revealing experience.
We review the 10-year RECONS (Research Consortium on Nearby Stars) effort to take an accurate census of all objects within 10 pc and outside of the Solar System. The result is an accurate cross-sectional study of your neighbors, who tend to be small and red, and lurk unseen in the night. Recent additions to the neighborhood include a few brown dwarfs and extrasolar planets.
We will also introduce you to more than a dozen of your newest neighbors, discovered during a large southern sky parallax effort known as CTIOPI (CTIO Parallax Investigation). This work has been carried out on the CTIO 0.9m and 1.5m telescopes since 1999 under the auspices of the NOAO Surveys Program, and since February 2003 as a part of the SMARTS Consortium. Only by watching your neighbors for several years can you really be sure what they're up to, and we'll show you that some of them have hidden partners-in-crime. The first hints of these partners have been revealed via astrometric perturbations found during CTIOPI.
