Betelgeuse
Ameenah Elam
About The Name
Arabic for "shoulder of the giant".
Could also mean "hand of al-jauza"
where al-jauza is the Arabs' "Central
One". Also known as the Martial Star.
The Fame!
Betelgeuse was the first star
seen as a sphere instead of a
point of light by the Hubble
Space Telescope on March 3,
1995.
Possibly will be the very next
supernova in our galaxy.
Did you know?
Betelgeuse is one of the biggest
stars that sits in Orion.
Only 9 other stars that appears
brighter than Betelgeuse, making
it the 10th brightest star in the
sky
Since it’s in its dying stage, it will
soon become a supernova.
Its Size
This Red Supergiant is about 13,000
times brighter and over 1,000 times
larger than our sun.
It’s also around 15 times the mass of
the Sun and about 650 times its
diameter.
More Facts
Betelgeuse gives off 50,000
times more light than the
Sun.
Plus, it’s 500 to 640 light
years from Earth.
Magnitude and
Temperature
Betelgeuse’s apparent
magnitude is .06 to .75.
Its absolute magnitude is 5.6.
It’s been reported in the last
decade that it has surface
temperatures between 3,500
to 3,600K.
The Life
While our Sun will last another 6 billion
years, Betelgeuse will be lucky to last
another 100,000.
Dying Star
The super-giant red star Betelgeuse in
Orion’s nebula is predicted to
cataclysmically explode, and the
impending supernova may even reach
Earth -- someday.
“This old star is running out of fuel in its
center,” Carter told News.com.au. “This fuel
keeps Betelgeuse shining and supported.
When this fuel runs out the star will
literally collapse in upon itself and it will
do so very quickly.”
However, these are only theories.
Betelgeuse has been
mentioned in a few movies
such as:
The Sirens of Titan
Planet of the Apes
Dune
The Robots of Dawn
