Alpha (α) Orionis

Alpha (α) Orionis, commonly known as Betelgeuse, is a bright, reddish star located in the constellation Orion. It is a supergiant star, meaning it is very large and luminous, much bigger than our Sun. Betelgeuse is nearing the end of its life and will eventually explode as a supernova. Its reddish color comes from its relatively cool surface temperature. Positioned around 640 light-years away, it is one of the most prominent and recognizable stars in the night sky, offering valuable insights into stellar evolution for astronomers.
