Originally from ticket #7308.
1st Question: If I entered a specific date about 6,000 years ago, does the
program tell/show me where “North” is vis-à-vis the Earth’s axis of
rotation?
(Today, the Earth’s axis of rotation is roughly pointing towards Polaris,
and it was pointed towards a difference star.
Polaris will not always be the Pole Star or North Star. The Earth's rotation
axis happens to be pointing almost exactly at Polaris now, but in 13,000
years the precession of the rotation axis will mean that the bright star
Vega in the constellation Lyra will be approximately at the North Celestial
Pole, while in 26,000 more years Polaris will once again be the Pole Star.)
2nd Question: If I entered a specific date about 5,000 years ago, will the
program tell me if their was a eclipse that day?
