Astronomy in the time of Abraham

[_Nimrod]

As I recall, the BoAbr which Joseph Smith claimed to have translated from the KEP includes, according to Joseph Smith, Abraham's understanding of astronomy.

Has a comparison of the understanding of astronomy in the late 18th, early 19th century been compared to the astronomy set forth in the Joseph Smith translated BoAbr?

Are there any ancient writings that include an astronomical understanding that comports with that set forth in the Joseph Smith translated BoAbr?
