Does the planet Jupiter have a surface?
It is not yet known if Jupiter has a solid surface. If it does, then the solid part of the planet can only make up a very small fraction of the volume of the planet. Saying that the Jupiter’s atmosphere constitutes a “surface” (as some answerers have proposed) is not really correct in that one cannot point to a surface at which the atmosphere “ends”. Like Earth’s atmosphere, Jupiter’s atmosphere simply becomes more and more tenuous as one moves further from the planet (in an approximately exponentially decreasing fashion). Picking a pressure at which the atmosphere “ends” is a arbitrary choice.
