ACTIVITY: Several tiny asteroids, all with the same mass and initial horizontal velocity, are positioned a short distance away from a planet. Animate the system forward and observe what happens. Q&A: 1. What do you notice about the speeds of the asteroids as they come close to and move away from the planet? 2. What do you notice about the distribution of the asteroids around the planet as time goes on? (Hint: Think of the rings of Saturn.)</COMMENTS> <SHOWCOMMENTS>TRUE</SHOWCOMMENTS> <BODY> <MASS>5.98e+24</MASS> <RADIUS>6.378e+06</RADIUS> <POSX>0</POSX> <POSY>0</POSY> <POSZ>0</POSZ>
