Why the path of planets is elliptical not circular?
I see. Is there any advantage of having elliptical orbits for planets?
There is no real advantage to having an elliptical orbit as such, but it does allow for variations in temperature and solar radiation. When a planet is closest to the sun (at perihelion), it receives more solar radiation and is hotter. When it is furthest away (at aphelion), it receives less solar radiation and is cooler.
