Nearly every aspect of astronomy is related in some way to the existence of gravity and to the motions which are responsible for a balance against gravity
How does this balance play a role for the miscellaneous objects of the solar system (i.e., the asteroids and comets)? How can some aspect of this be used as a tool to determine masses in the solar system?
