The shape of orbit varies from oval to round. Accordingly the velocity also varies. We can explain it using Kepler's law of motion.
Explanation:
Orbit is a path around every object in space. Every object moves in an orbit and the shape of every orbit is different. This shape of orbit affects the orbital velocity.
Now velocity of a planet depends upon the distance of a particular planet from the sun. A planet will move fast if it comes closer to the sun but if on an orbit if goes away from the sun than it will move slow. This is supported by Kepler's law of motion.
If the orbit has circular shape than its distance from sun will remain same and so speed will not vary much but in case of oval shape will be close to the sun at one point and far away from the sun at other point so the speed will vary lot.
Shape of planetary orbits greatly affects their orbital velocity of the planets.
The shape of planetary orbits greatly affects their orbital velocity because the oval shape of the orbits moves with more speed as compared to circular orbits. A planet will move with high speed an faster if it comes closer to the sun but if on an orbit if goes away from the sun than it will move slow.
This type of motion occurs in oval shape orbit in which at some points the distance is lower so it moves with more speed. This phenomenon is supported by Kepler's law of motion. Kepler's laws of planetary motion can be stated that All planets move about the Sun in elliptical orbits, having the Sun as one of the foci so we can conclude that shape of planetary orbits greatly affects their orbital velocity of the planets.
