Apart from the obvious evidences of astronomy in the 'Polar' passages of the pyramids and the orientation of the Sphinx, Giza demonstrates several other instances of astronomical influences at the time of construction.

It is a well known fact that the N/S axis of the Khufu (Cheops) is only 03' 06" to the west of true north, a fact which confirms the levels of skill/accuracy attained by the ancient Egyptian astronomers (and builders).

It has been noted that (Through accident or design), the Great pyramid of Giza is a particularly accurate scale model (1:43,200), of the Earth's dimensions.

The number 43,200 is a specific 'precessionary' number, one of several that are repeated in Egyptian myth, text and construction.

The Precessionary cycle lasts approximately 25,920 years, which results in a new constellation appearing on the horizon each 2,160 years.... and 2,160 x 2 = 4,320 years.

The Giza plateau was built on the 30th latitude.

It seems unlikely that when combined with the other specific geometric and astronomic figures in the dimensions at Giza, that the site was chosen for its latitude accidentally. The same latitude was chosen by the Persians (Persopolis), The Sumerians, (Larsa), and the Tibetans (Lhasa) for their sacred centres.

The Astronomical significance of the three small pyramids next to Khufu's pyramid.

In the common opinion of Egyptologists, the small pyramids next to the great pyramid of Khufu served as burial places for the relatives of the Pharaoh. Certain facts, which have not been previously considered, indicate that there is a chance that the pyramids — due to their ground plan arrangement — are not only burial places but also the components of a yearly calendar. Research by the Hungarian architect András Göczey has demonstrated that there are clear alignments between Khufu's pyramid and the three smaller burial pyramids of his relatives. The Basic Principles of the 'Khufu Calendar' are as follows:

Göczey has demonstrated that when the three smaller pyramids were complete, the apex's of their shadows would have cast a 'shadow point' on the Great pyramid at significant times of the year (The solstices and Equinoxes). The YouTube video above demonstrates the procedure in its basic form.
