We present the discovery of a faint Milky Way satellite, Laevens 2/Triangulum II, found in the Panoramic Survey Telescope And Rapid Response System 3π imaging data and confirmed with follow-up wide-field photometry from the Large Binocular Cameras. The stellar system, with an absolute magnitude of MV = −1.8 ± 0.5, a heliocentric distance of 30 − 2 + 2 kpc ?> , and a half-mass–radius of 34 − 8 + 9 pc ?> , shows remarkable similarity to faint, nearby, small satellites such as Willman 1, Segue 1…
