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 ...

Since then, the perihelion and aphelion dates have drifted by a day every 58 years. In the short-term, the dates can vary up to two days from one year to another. Mathematicians and astronomers estimate that in 6430, over 4000 years from now, the perihelion will coincide with the March ...
Perihelion can fall anywhere between January 2 and January 6 in a given year. At that point in its orbit, the Earth is over 91 million from the Sun, a difference of about three million miles from its farthest point, oraphelion. When Is Aphelion in 2025? Aphelion occurs onJuly 3, 2025....

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 ...
