Its story

15 Trianguli is a cool red M-type star set against the small figure of the Triangle, that geometric wedge north of Aries. Its atmosphere, far cooler than the Sun's, soaks its light in a deep red; from some 632 light-years it reaches magnitude 5.38 only thanks to the vast size of an advanced giant. The light arriving tonight began its journey around 1394, still a century before the great oceanic voyages.
