Constellation: Orion Betelgeuse
(Bet' l 'jooz)
The first star I learned as boy. It is the 8th
brightest star in the night sky, and second to Rigel in the
Betelgeuse, is classified as a red supergiant, type M21ab, meaning it
is one of the largest and most luminous of the observable stars, only
aboutr 640 light-years away from us. Astronomers are not sure of
Betelgeuse’s mass though. Anywhere from 5 to 30 times of
our sun, its absolute magnitude is about -6.02.
Living fast and dying young, compared to our sun, Betelgeuse is a
youngster only about 10 million years old. It had a hard youth,
having been ejected from its birthplace in near the Orion’s belt,
Betelgeuse is running away at supersonic speed, some 30 km a
second. This is fast enough to create a bow shock some 4
Astronomers believe that Betelgeuse will go supernova within the next million years.
According to Bob Berman, Astronomy Magazine, Oct 17 issue, pg 10.
The spelling Bet'l'jooz, is Sumerian. They saw Betelgeuse
as "the arm-pit of the sheep", as the constellation struck them as a
sheep & not a hunter. Gotta love those Sumerians!
