Mercury, the closest planet to the sun, has the most eccentric orbit, with the difference between the distance at perihelion and aphelion being 0.17 AU. That is quite a lot for Mercury, which orbits on average at only 0.39 AU. "It's the gravitational effects of all the other bodies in ...

The difference of the Earth’s orbital shape from a perfect circle is known as its eccentricity. An eccentricity value of 0 is a circular orbit, while values between 0 and 1 describe an elliptical orbit.Aphelion in Zhengzhou, Henan, China is on...
The name comes from the Greek words ‘peri’ (near) and ‘helios’ (sun). The aphelion is the exact opposite The opposite of perihelion is aphelion, which is when Earth is farthest from the sun. Distance is still very far The difference in distance between Earth's nearest point to the ...
perihelion than at aphelion, on account of the difference in density at the two points, but this difference contains the eccentricity as a factor, and it is for this reason that the rate of decrease of the eccentricity and the motion of the perihelion would be of the same order of ...
