what is the axis of the planet
The right-hand rule helps amateur astronomers understand axial tilt. When the fingers of the right hand are curled in the direction of the planet's rotation, the thumb points in the direction of the planet's North Pole. An axis is an invisible line around which an object rotates, or spins. The object can be a tiny particle, smaller than a single atom. Or it could be a star with the mass of a thousand suns.
