Where does potential energy come from

If earth were to every pull back on that object, this is where its kinetic energy will come from. Regarding some other planet pulling it, note that there is currently potential energy stored in the object(when it is onearth), in the other planet's gravitational field.

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.

Because the sun is the biggest and if the sun orbits the earth we will be dead probably
