Betelgeuse – Alpha Orionis

This is the star Betelgeuse in the constellation Orion. In the last few weeks there has been some discussion about the dimming of this star and the possibility of it going supernova. While it will explode someday, the recent dimming is probably due to its variability and not that it is getting ready to explode (maybe). You can read more about this at EarthSky.org .
Here are some interesting facts about this 9th brightest star in the sky. The name Betelgeuse is derived from the Arabic Yad al-Jauzā’ meaning “the hand of Orion”. Betelgeuse is a red supergiant, 20 times the mass of the sun, is a variable star and lies at a distance around 640 (I’ve found various ranges, this number seems like the largest I have come across) light-years away from Earth.
