Well, there is much more to see and do in the Solar System, but this tour takes you well beyond! Next stop is our nearest star: Alpha Centauri. Your Journey will take a while using fusion power, so you will probably sleep for a few months. When you finally wake up near Alpha Centauri, you realize that Alpha Centauri is actually a binary star system! The two stars, Alpha-Cen-A and Alpha-Cen-B, have different masses; Alpha-Cen-A is more massive than Alpha-Cen-B.
(a)Draw a schematic diagram representing the orbits of the two stars, labeling the starsand indicating their orbital paths. Assume circular orbits. What is located at the center of their orbits?
(b)What is the ratio of the orbital radii of the two stars (R_A/R_B)? Show your work.
(c)What is the ratio of the orbital periods of the two stars (T_A/T_B)? Explain.

Chapier 2i. Note: you needn't derive Kepler's laws-but do mention when you are using them, an describe the physical concepts involved and the meanings behind the variables. u) Consider two stars Mi and M; bound together by their mutual gravitational force (and isolated from other forces) moving in elliptical orbits (of eccentricity e and semi-major axes ai and az) at distances 11 in n and r from their center of mass located at...

Question 7 (0.5 points) What causes the Moon to move about 12° across the sky from one night to the next (at the same time of night, of course)? O Because the Earth is turning on its axis. O Because the Moon is moving in its orbit. The Sun has also moved 15° across the sky and gravitationally pulls the Moon with it. The celestial sphere the Moon is attached to has moved 15°. O It is an optical illusion....
