The earth tilt is 23 degrees. Where are we in the cycle? How many years before it is zero degrees?
I believe the axial period is 42,000 years and we are descending to zero degrees. How many years until this happens.
The tilt of the Earth's axis is closer to 23.5°, and varies between 22.1° and 24.5°, with a 42,000 year period.This is measured from a perpendicular line to the ecliptic plane. This angle is otherwise very stable and never approaches a value or
