Snaping Object to another moving object

Hi, I use leap motion in a car game. I would like to see my hands on the steering wheel, but of course leap motion goes crazy when the sensor does not see the fingers. Therefore, I would like to snap my fingers to the steering wheel as soon as they are near the steering wheel. So that the visualization does not wobble back and forth. So in principle I want an object1, as soon as it comes close to the other object2, to snaps to the nearest point, but the object2 is moving.
