Betelgeuse is a red supergiant star found in the constellation Orion. When viewed with the naked eye, Betelgeuse is visibly bigger than most stars in the sky and has a clear orange color. This star is so big if it were in our solar system it would stretch out to Jupiter, swallowing up Mercury, Venus, Earth & Mars. Betelgeuse is a relatively young star but due to its enormous size its life span is much shorter and it will end in a super nova, some scientists believe soon enough to be witnessed by human civilization. At 640 light years away from Earth, Betelgeuse is visibly big inside the telescope.
