Trappist 1 is an dim ultra cool red dwarf star located 39 light years away in the constellation of Aquarius. In size, it is only slightly larger than Jupiter but more massive. Despite only being 39 light years away, due to its size and type, it is a dim 18.8 magnitude in the "V" (Green) band and 16.5 magnitude in "R" (Red) band. It is suspected of having seven terrestrial planets orbiting it, detected by transits of the planets across the star's disk. Several could be in a zone where liquid water could exist.
