it's just a waste of space.

And, on top of that, it is totally over rated, it is only 3 stars!


Yeah, but that's because Orion has lost some weight so has had to take
in his belt! ;-P

Alnitak
Alnitak (ζ Orionis) is a triple star system at the eastern end of
Orion's belt and is 1,260 light-years from the Earth. Alnitak B is a
4th-magnitude B-type star which orbits Alnitak A every 1,500 years.
The primary (Alnitak A) is itself a close binary, comprising Alnitak
Aa (a blue supergiant of spectral type O9.7 Ibe and an apparent
magnitude of 2.0) and Alnitak Ab (a blue dwarf of spectral type O9V
and an apparent magnitude of about 4). Alnitak Aa is estimated as
being up to 28 times as massive as the Sun, and to have a diameter 20
times greater. It is the brightest star of class O in the night sky.

Alnilam
Alnilam (ε Orionis) is a supergiant, approximately 2,000 light-years
away from Earth and magnitude 1.70. It is the 29th-brightest star in
the sky and the fourth-brightest in Orion. It is 375,000 times more
luminous than the Sun.[5] Its spectrum serves as one of the stable
anchor points by which other stars are classified.

Mintaka
Mintaka (δ Orionis) is 1,200 light-years away and shines with
magnitude 2.21. Mintaka is 90,000 times more luminous than the Sun.
Mintaka is a double star. The two stars orbit around each other every
5.73 days.[6]


Gee Whiz!! Looky Looky! Someone can Cut and Paste from Wikipedia!!
