Following the 1983 IRAS detection and subsequent imaging of its extensive dusty circumstellar disk, β Pictoris became the prototypical and most studied example of a potential forming planetary system. Here we report the identification of 17 star systems, each with one or more characteristics indicative of extreme youth, that are moving through space together with β Pic. This diverse set of ~12 million yr old star systems, which includes a ~35 Jupiter mass brown dwarf, and a wide assortment of dusty circumstellar disks, is the comoving, youthful group closest to Earth. Their unique combination of youth and proximity to Earth makes group members-many of which have masses similar to that of the Sun-prime candidates for imaging of warm planets and dusty circumstellar disks with ground- and space-based telescopes.
