Detailed explanation-1: -Therefore the planet moves faster when it is nearer the Sun and slower when it is farther from the Sun. A planet moves with constantly changing speed as it moves about its orbit. The fastest a planet moves is at perihelion (closest) and the slowest is at aphelion (farthest).
Detailed explanation-2: -As the sun loses its momentum and mass, the Earth can slowly slip away from the sun’s pull. Our planet is assuredly not growing closer to the sun in orbit; in fact, our planet is slowly inching away from the sun.
Detailed explanation-3: -Relative to the stars, however, the planets generally move from west to east, like the Sun and Moon. Their speeds vary, but Mercury is the fastest, followed by Venus, Mars, Jupiter, and then Saturn, the slowest. This motion is called direct motion.
