Please excuse if this has been asked and I just didn't find it.

I have found several references that indicate that the inclination of Earth's orbit varies over a period of ~70,000 years, but I can't seem to find anything that tells what the range of variation is. I know that it's currently at 1.57° to the invariable plane, but I'm looking for the value of the maximum tilt.

Thanks in advance!

In a solar system model by Varadi Runnegar and Ghil Earth's inclination varies between 0 and about 0.05 radians (or about 3 degrees)

The variation is rather chaotic, but you may note that there seems to have been a qualitative change in the pattern about 60-70 million years ago
