Orbital geometry of earth
As seen from Earth, the planet's orbital prograde motion makes the Sun appear to move with respect to other stars at a rate of about 1° eastward per solar day (or a Sun or Moon diameter every 12 hours).

WebThe geometry of an orbiting object in space is a circle (or an ellipse) but confined to a plane. To better understand the geometry of several orbiting objects, we need to investigate the orientation of each of the orbiting planes. The orbit of one object can be measured by an angle relative to another plane, called the inclination.
