A planet is observed to have a satellite that orbits the planet once in every 104 hours. The distance to the planet from Earth is R = 3.4 x 108 km. The maximum angle that the satellite makes with the planet is ? = 0.064 degrees. From this data, calculate the mass of the planet. Write your answer in terms of 1021 kg. (i.e. if the answer is A x 1023, write it as B x 1021, then enter B as your answer).
