planetary centripetal acceleration calculator

gravitational constant (g) = 6.6726 x 10-11N-m2/kg2
i want to calculate
planet mass (m) = kg
planet radius (r) = m
acceleration due to gravity (a) = m/s2
 

acceleration due to gravity

acceleration due to gravity: a = gm/r2

here:

g = gravitational constant = 6.6726 x 10-11N-m2/kg2

m = planet mass

r = planet radius
