The Earth’s orbit does not wobble, the poles are at an angle to the sun where the north pole is angled toward the sun on one side of the orbit and angled away from the sun on the opposite side of the orbit.
That galaxy photo is probably a disruption from another galaxy passing nearby, not normal orbital dynamics.
Yes, the galaxy is easy to understand. The Analemma not so much. But alright, thanks.
Great explanation! I’ve better examples of an analemma, but this one is basically the same as any others I have seen. It does take determination and patience to pull it off.
indeed it does wobble over a year. the north pole tips towards the sun when its furthest away in the summer and in the winter, 3 million miles closer to the sun, the north pole tips away from the sun... hence the reason for tropic of cancer, tropic of capricorn...
