Gravitation on Planets...earth physics?

A satellite is in a circular orbit just above the surface of the Moon. (The radius of the Moon is 1738 km.

What is the sattelite's acceleration in m/s-squared?

I am able to calculate the velocity, but then I'm stuck....

The acceleration at the surface is shown as 1.23E-5 m/s^2. The page contains the details.
