I'm trying to calculate the orbital period of an Earth-sized planet at 15 AUs out from a star that's about 7.5 times the mass of the Sun. I'm guestimating around 50 years, but Kepler's laws don't seem to be much help when looking for absolutes; you need a known quantity within the same solar system to compare against. Can anyone point me at the correct formulae? Thanks.
