FOUR QUESTIONS ON THE ADVANCE OF MERCURY'S PERIHELION
1. At what distance (in Km) does the Sun's center of mass lie from the center of mass of our solar system?
2. What kind of movement does the Sun perform around the center of mass of our solar system (circular, elliptical, etc) and what are the particulars of this orbit?
3. How much time (period, in years) does the Sun need to make a complete revolution around the center of mass of our solar system?
4. To what extent (expressed in ° degrees) does the Sun's movement (around the center of mass of our solar system) contribute to the advance of Mercury's perihelion?
