Ok so i think this question is impossible without another piece of info, but i just wanna post it and see if anyone is amazing enough to get it ^^

--> Two planets orbit a star of mass 10^32 kg. Planet A has a mass of 10^24 kg and planet B a mass of 10^26 kg. Planet A is 1.5x10^11 m from the star and takes 200 days to orbit the star. What is the radius of the orbit of planet B? <--
