it's just a waste of space.

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]
