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.
One of these is the tilt of the earth. The earth's axis of rotation is tilted about 23.5 degrees compared to the plane of the earth's orbit around the sun. The earthâs tilt is responsible for the seasons we experience.
