I will never understand how planets hang in the air

Looking at that picture of Jupiter, what holds it up. What stops it from falling down. 🤔😄

Jupiter, a beautiful gas giant planet that can fit all the other planets inside it. I recall first seeing it through my telescope when I was twelve. It's held in its orbit like the other planets by the gravitational pull of our sun, named Sol.

@PatKirby I wonder what aliens call Earth and our Sun.
I wonder if they call it Earth, Mercury, Venus, etc.
Or what other names they might have for them.

No, I don't believe that every whack-a-doodle that says they saw an alien is telling the truth, but there has to be life on other planets, however far away that they may be.

I figure they probably give the sun a name and assign the planets a number beginning with the closest to the sun. With that notation the planets Mercury, Venus and Earth would be designated Sol 1, Sol 2 and Sol 3 respectively. Who knows, maybe there's intelligent life here in our own solar system. The joke goes - well you don't see them spending billions and billions to come over here (so they must be intelligent). But I digress, there are way too many stars containing planets in the universe capable of sustaining intelligent life, with an increasing amount discovered well within the habitable "Goldilocks zone." And according to the Drake Equation (SETI Institute)...
...there's millions - specifically 15,600,000*. However if considering credible eye witness accounts, they describe having seen these...
