If on Earth one sees the moon as going around Earth. If on the sun,one sees the moon rotating around the SUN (albeit the moon is in a wobbly orbit around the Sun). Both are right, however, most would say Earth ( we are after all, on Earth, and very Earth centric in our thinking).

a) If the period on planet X is 2T, the acceleration of gravity (g) at the surface is 4 times less than Earth's, because Period = 2 pi sqrt(L/g) Since g = GM/R^2, if g is 1/4 as large as Earth's, and R is half the Earth's radius, M is 1/16 of Earth's. g(X) = g(...

Huh? g is not 9.8 on Earth. the acceleration at Earth's surface is 9.8m/s^2. The gravitational field at Earth is 9.8N/kg Why that number? The mass of the Earth, and the diameter of Earth determine it. g=G*MassEarth/radiusEarth^2
