planet X is observed (mass-M kg) to execute a circular orbit around celestial object YY. If the length of one planet-X year is 180 Earth-days, and it takes 20 light-seconds for light (velocity of light=3x108 m/s) to travel from YY to planet X, what is the mass of celestial object YY? How do your numbers change if a) the mass of X is doubled, compared to what you just calculated? b) at the original radius, the length of one planet-X year is doubled?

An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 1960 x 103 seconds (about 23 days) on average to complete one nearly circular revolution around the unnamed planet. If the distance from the center of the moon to the surface of the planet is 295.0 x 106 m and the planet has a radius of 3.70 x 10% m, calculate the moon's radial acceleration a.
