Orbits in th Solar System

All the planets orbits around the sun. The Earth ecliptic around the sun within 24 hours. Mecury, Venus, mars, and Earth have flat Ecliptic. the Sun is one of the main focusical points in the Solar System. Several years ago Kepler discovered the laws of planetery motion. These laws stated that Ehiptical orbit, planets are equal an area,which equals the time it rotates toward the sun; each time planet moves closer to the sun.The rotation of the planets; rotates faster. The movement and speed of each planet is determined by the sun's gravity.
