When the winter solstice arrives, the angular momentum of the Earth, its orbital angular momentum and its radius vector with the orbital focus in the Sun are in the same plane. This happens quite close to the perihelion (~2 weeks later), where both the orbital angular speed of the Earth and the curvature of the ellipse are at its maximum.
Is there any dynamical relationship for the major axis of our orbit to follow the direction of the rotational axis of the Earth, or it is just a coincidence and the perihelion could well be in, say, april?
EDIT: Yes, there is no observed resonance between the precession of the Earth ellipse and the Equinox precession (+1 for both answers and, thanks!). But the question goes in another direction. Perhaps there could be some tidal forces near the perihelion, related to the departures from the rigid solid model because the molten interior of the Earth, so that there could be some form of weak transference of momentum from proper to orbital (in analogy with the transference of momentum with the Moon, that nowadays slows down the Earth rotation and enlarges the mean distance to the Moon).
Has anybody developed that question analytically?
