Kleppner and Kolenkow, An introduction to mechanics
The period of the precession is 26000 years. 13000 years from now, the polar axis will not point toward Polaris, the current north star; it will point 2 × 231 2 ◦ = 47◦ away. Orion and Sirius, those familiar winter guides, will then shine in the midsummer sky, and the winter solstice will occur in June.
