HW000315

1. Show that the Sun is not at rest in the center of the Solar System by calculating the distance from the Sun's
   center to the center of mass of the Sun-Jupiter system.
2. Using the mass and the size of the Sun, compute the Sun's average density. Compare your answer to the
   average densities of the outer planets.
3. Calculate the wavelengths at which the photosphere, chromosphere, and corona emit the most radiation.
   Explain how your results suggest the best way to observe and study these regions of the solar atmosphere.
