Suppose an asteroid has a tiny moon orbiting around it (which does occur). If the moon is 1.8 km wide, is 114 km from the center of the asteroid (which is 54 km long), and assuming the moon has a circular orbit around the asteroid of period 30 h), what is the mass density of the asteroid (if its volume is 1.39 x 104 km3)
