When people talk about the “sound” of a planetary object. Is it really how they would sound like if they were not in the vacuum of space?

That would depend on who these “people” are and which “planetary objects” they’re talking about. If it’s LIGO people talking about gravitational waves from black holes the answer is no, it’s just an analogy. I believe we have measured what is essentially the sound on the surface of the sun.
no its just a wave form that is translated into sound. No matter how close you get to a black hole, you can’t hear gravity. Quirks of a universe with particles and wave-forms.
It does not actually exist in that form; but the wave-forms are translated into a scale we can interpret directly without tools and in a sense… with the human mind being so flexible, its an acceptable proxy. By measuring the waves or patterns of a black hole or the “murmuring” on the sea of a distant icy moon, their equivalent in the audible range can be recorded digitally once we process down here on earth, after we “scaled” up or down to our audible level in Hz. Plus accounting for atmospheric content.. i don’t envy the workflow.
So far.. it has lent itself to cinema VFX where simulating the sound is useful for shows like Cosmos or a general financial opportunity in sound archives for future digital universes like star wars.. anyways, i digress and hope you have gotten the idea.
