Beta Orionis, "Rigel", is a
"supergiant", and the 7th brightest
star in the sky. It has luminosity in
the area of 57,000 times the sun,
making it one of the most luminous
known stars in the galaxy. Were the
star the same distance as Sirius (8
light years, vs. 900 light years), it
would blaze away at a magnitude of -10!
Rigel is a double star with a 6.7
magnitude companion easily visible in
a small telescope.
