A main sequence blue star, called the Blue Phoenix, has a mass of more than 50 Msun, and is in a circular orbit about the center of the Galaxy. Also the Blue Phoenix is a distance of 20,000 L-Y from the center of the Galaxy and it's orbital speed is estimated at 280Km/sec. How many years will it take for this bright star to complete one orbit around the galaxy? What stage of life will this star be in by the time it completes this one revolution?Discuss your rationale for reaching your conclusion. (Msun is the mass of the sun, and the Blue Phoenix is an imaginary star, you will not find it on any star chart)
