How does earth rotates in an elliptical around sun instead of circular if influenced by centripetal force.?
Centrifugal surely! The forces employed are string and gravity, basically the Earth like the other planets want to fly off into the void but the suns gravitational pull, like a piece of string, prevents it from happening. The moon acts as a counterbalance to stop us from wobbling about too much and stops us from falling over on our side like Uranus. Given that the pull of gravity from the sun isn’t constant it fluctuates + or – x which means that the orbit isn’t a circle or even on a plane as it moves up and down as well so we end up with a wavy ellipse. The whole cosmic balance thing is truly wondrous, maybe I should start believing in a cosmic watchmaker. Sorry about the lack of jargon but you can’t have everything in this life!
