Your thinking is correct. It is the sum of all the forces which produces the final result.

However, the force you feel from distance objects are quite weak. The gravitational force gets much weaker for every increase in distance. The inverse square law applies. If you double the distance of an object from you, you will feel (1/2)^2 (or 1/4) the force. Therefore, the distance of celestial bodies are not felt hardly at all.

We know time flies, we just can't see its wings.
