                    Star Facts

Betelguese, also known as Alpha Orionis, is the tenth brightest star in the night sky. This star is approximately 642.5 light years away from earth. The diameter is approximately 850 million miles (1.4 billion km) wide - 1000 times that of the Sun. Because of its orange-red color and big size, Betelgeuse is classified as a Red Super Giant. Due to its enormous size Betelgeuse is around 100,000 times more luminous than the sun. Its surface temperature fluctuates around 3,500 K.

At 10 million years old, Betelgeuse is nearing it's life span and will eventually explode as a Supernova. When Betelgeuse explodes it will appear as bright as the moon in the night sky for several weeks and may even be visible during the day. Fortunately, It will not cause any damage to Earth.
