We present the discovery of a faint Milky Way satellite , Laevens 2/Triangulum II , found in the Panoramic Survey Telescope And Rapid Response System ( Pan-STARRS 1 ) 3 \pi imaging data and confirmed with follow-up wide-field photometry from the Large Binocular Cameras .
The stellar system , with an absolute magnitude of M _ { V } = -1.8 \pm 0.5 , a heliocentric distance of 30 ^ { +2 } _ { -2 } { kpc } , and a half-mass radius of 34 ^ { +9 } _ { -8 } { pc } , shows remarkable similarity to faint , nearby , small satellites such as Willman 1 , Segue 1 , Segue 2 , and Boötes II .
The discovery of Laevens 2/Triangulum II further populates the region of parameter space for which the boundary between dwarf galaxies and globular clusters becomes tenuous .
Follow-up spectroscopy will ultimately determine the nature of this new satellite , whose spatial location hints at a possible connection with the complex Triangulum-Andromeda stellar structures .
