Graham Mccarthy · Answer 1

The acceleration of gravity is proportional to the planet's mass, and inversely proportional to the square of the planet's radius.

So on this particular planet, the acceleration of gravity will be

(Earth gravity) x (3.57 / 1.61²)

That's (9.81 m/s²) x (1.377) = 13.51 m/s²
