Caput Triangulu, Metallah, Ras al Mothallah,
Alpha Trianguli, 2 Trianguli

This orange subgiant, about 63 light years from Earth, takes its name from the Arabic al muthallath, meaning 'the Triangle' and, despite its 'Alpha' designation, is the second brightest star in the northern constellation of that name. Given its triangular associations, it is appropriate that Mothallah is a ternary or triple system, with the main star having two companions.
