Orbital Rotations

Each planet’s orbit around the sun is an ellipse. The Sun is always located at one focus of the elliptical orbit. Planets are sometimes closer to the sun (perihelion) and farther (aphelion)

The imaginary line joining a planet and the sun sweeps equal areas of space in equal times as the planet orbits. Planets move faster as they are near perihelion, And slower as they are at aphelion (away)

The period for a planet to orbit the sun increases rapidly with the radius of its orbit (This tells the distance between plants and how long they take to revolve around the sun.)

Laws that describe the motions of the planets in the Solar System.

The shift of the position of a nearby body as the earth orbits the sun. As an observer’s position changes, the viewpoint will as well.
