The discussion centers on the feasibility of levitating objects above the surface of a planet smaller than Earth, which possesses a lesser gravitational pull. Participants clarify that all matter, regardless of size, exerts gravitational force, making it impossible for an object to float indefinitely above the surface without touching it. The consensus is that gravity will always pull objects towards each other, negating the possibility of sustained levitation in this context.

What object? What else do you know about the planet? I will assume you are talking about some small object (compared to the planet). What do you think will happen based on what you know about gravity?PacersRule07 said:If I made a planet that was smaller than Earth's and thus had a lesser gravitational pull, would I be able to reach a point of gravity where the object wouldn't completely touch the surface but would instead float just above the surface?
