Jupiter is shinning bright just now High up in the east. Its very bright just left to this star constellation Orion.You can tell a planet as apposed to a star as it does not twinkle. The top left star in Orion Betelgeuse is some 600 light years away so as you look at it now you are seeing it as it was 600 years ago. So it may not exist now So given the 600 light-year distance to Betelgeuse (about 40 million times further away from us than our Sun), the apparent peak luminosity is 700.000 times brighter than the sun.
