Terra's AXIAL TILT is not constant; it fluctuates slightly over long periods, with a cycle of about 41,000 years, varying between 22.1° and 24.5°, according to the British Geological Survey and 22.1 and 24.5 degrees according to NASA.
Terra's orbit.
The last time the tilt was
at 24.5 degrees was roughly 10,000 years ago, and the next time it will
be at that angle is in about 31,000 years.
