The constellation of Lacerta comprises a trail of relatively faint stars running north to south between Andromeda and Cygnus. At the southern tip of this formation, where it approaches Pegasus, is the orange star 1 Lacertae. With an apparent magnitude of just +4.1, this star is visible to the naked eye, but far from brilliant. In fact it is rather more luminous than the view from Earth suggests: it is in fact a giant star, and at ten parsecs' distance (the standard for calculating absolute magnitude) it would outshine Sirius. It is rather more than ten parsecs from Earth, however: actually it lies nearly twenty times further away than that, at 190 parsecs, or 621 light years.
