Trappist-1 (7 ExoPlanets)

TRAPPIST-1, also known as 2MASS J23062928-0502285,[6] is an ultracool dwarf star[4][7] located 39.13 light-years (12.0 pc) away in the constellation Aquarius.

A team of astronomers headed by Michaël Gillon of the Institut d’Astrophysique et Géophysique at the University of Liège[8] in Belgium used the TRAPPIST (Transiting Planets and Planetesimals Small Telescope) telescope at the La Silla Observatory in the Atacama desert, Chile,[9] to observe TRAPPIST-1 and search for orbiting planets. By utilising transit photometry, they discovered seven Earth-sized planets orbiting the dwarf star; the innermost two are tidally locked to their host star while the outermost appears to lie either within the system's habitable zone or just outside of it.[7][10] The team made their observations from September to December 2015 and published its findings in the May 2016 issue of the journal Nature.[9][11]
