buoyancy
The force that keeps objects floating is called buoyancy. It is the upward force exerted by a fluid that opposes the weight of an immersed object.
The buoyant force on an object floating in water is equal to the weight of the water displaced by the object. This force acts in the upward direction, opposing the force of gravity acting downward on the object. If the object is floating, it means that the buoyant force is equal to the weight of the object, providing balance.
The gravitational force and the buoyant force.
It sounds like you are looking for the term "buoyant force".
buoyancy
The force applied would be zero as a freely floating astronaut feels weightlessness as the gravitational force acting on him is zero.

It's called the buoyancy force.
Floating is the medical term used to describe the rasping or filing of a horses' teeth. The term originated from the masonry term which describes the leveling of a row of bricks (floating).
The force acting on a floating object is the buoyant force, which is equal to the weight of the fluid displaced by the object. This force pushes the object upward, counteracting the force of gravity pulling it downward. If the buoyant force is equal to or greater than the weight of the object, it will float.
When it's floating perfectly still, neither sinking nor floating upwards.
