Things that make you hmmm.
Using a see-saw to explain gravity and orbits.
Our Earth does not orbit the Sun (technically). Jupiter does not orbit the Sun at all... in no way does the planet Jupiter Orbit our Sun.
All objects with a mass have gravity and all things with mass orbit the common mathematical center of the nearest more powerful object. Hence why our moon orbits earth and not the sun.
Jupiter orbits a point that is just outside the Suns Surface. ( 1/1000th of the distance between the Sun and Jupiter)
Earth orbits a point that is just outside the Sun's Center.
When two bodies of equal mass are gravitationally locked, they do not orbit at all. They wobble because the common center of mass is equal distance from their center.
To understand this, imagine the person on the right is the Sun, and the person on the left is the planet Jupiter.
The 40 pound Jupiter on the left Orbits the point of the Center Of Balance between the 160 pound Sun and its 40 pound self.
This also helps understand why most orbits are elliptical.
