The classic triangle, Triangulum, lies at the center of the picture,
the Alpha star Mothallah to the right. Beta and Gamma are counterclockwise
around the triangle from Mothallah, while fainter Delta is tucked
just up and to the left of Gamma. (The star to the lower right of
Gamma is 7 Trianguli.)
Mirach and Almach of
(Beta and Gamma Andromedae) lie at the top, Mirach at right. Hamal in
Aries is at bottom. The "Triangulum Spiral (M 33),"
a nearby galaxy 2.7 million light years away
that under ideal conditions can be seen with the naked
eye, is up and to the right of Mothallah
A tri of modest stars below Triangulum, made (clockwise from
the top) of 6, 10, and 12 Trianguli, represents the defunct modern
constellation "Triangulum Minus," the "Smaller Triangle."
