Is a moon floating on the atmosphere of a gas giant possible?

+0
−0

I have an idea: can a moon float on the atmosphere of a gas giant, just like a piece of wood floats on the water? It is based on the following situation:

  1. The density of the atmosphere increases when getting deeper to the core.

  2. The moon spins inwards to the planet slowly because of some damping such as affected by other moons or molecular cloud.

  3. The rotational speed of atmosphere is nearly the same as the orbital speed of moon so that it would not collide with the atmosphere violently.

Is that kind of situation possible?
