Scientist sees pyramid secrets in the stars The ancient Egyptians lined up their pyramids to
the north because they believed that their pharaohs became stars in
the northern sky after they died. The Egyptians used two stars,
Kochab and Miza, to find true north. It was only in 2467 BC that
the celestial north pole was situated exactly between the two stars
Kochab and Mizar. The Egyptians started building the Great Pyramid
of Giza about 11 years before 2467 BC, which is why it is slightly
off true north orientation. NOVEMBER 16, 2000
