What is the centripetal acceleration of the Moon? The period of the Moon's orbit about the Earth is 27.3 days, measured with respect to the fixed stars. The radius of the Moon's orbit is
RM = 3.85 · 108 m.

To quote one of our very good math and science tutors:
“You will find here at Jiskha that long series of questions, posted with no evidence of effort or thought by the person posting, will not be answered. We will gladly respond to your future questions in which your thoughts are included.” 
Centripetal acceleration in a circular orbit of radius R is
a = V^2/R
You can get V from the orbit radius, R, and the period, P.
V = 2*pi*R/P
Make sure P is in seconds when you compute V. 
2.73*10^3
