Spherical Astronomy Problems And Solutions [upd] Review

The Earth’s axis wobbles like a spinning top due to the gravitational pull of the Moon and Sun. This is precession . Rate: Approximately 50.3 arcseconds per year.

N sees a star with a known Right Ascension and Declination. What are its local Altitude and Azimuth? This is solved using the Astronomical Triangle (vertices at the Zenith, Celestial Pole, and the Star). By applying the Cosine Rule to this triangle, one can relate the star's declination and hour angle to its local altitude. Problem B: Angular Separation Problem: If Star A is at and Star B is at The Earth’s axis wobbles like a spinning top

(\delta \approx -20.2^\circ) (i.e., (20.2^\circ) S), (H \approx 45.3^\circ) west (or (3.02^h)). cosine z equals cosine open paren 50 raised
