Hi Professor Graham! Thank you so much for stopping by! Thank you so much for your encouragement and supports from day 1 I came to 糖心Vlog传媒. I wouldn’t choose physics major without you! (So does this poster and IS!)

Yes! In figure in 2D Polar coordinate, we represent the direction of zenith as red dashed line along dumbbell’s rod. The direction of it will change as dumbbell tumbles. Some reasons to cause dumbbell doing tumbling motion are: asteroids’ highly irregular shape, gravity force caused by other neighbor planets. For example, Hyperion is sponge like with highly irregular shape, and Titan, one of the largest Saturn’s moons, has strong gravity force acting on Hyperion.

Thank you Carlos! “Sol” can be any center giant star that dominates asteroids in their system. For example, the sun in Sun-Earth-Moon system; Saturn in Saturn-Titan-Hyperion system.

Thank you Dr. Guarnera! We used Mathematica to do all the calculation and and simulations.

Thank you Dr. Lindner! I think it’s workable if we represent dumbbell’s position with respect to Sol. In our case, the position of dumbbell \delta r is relative to center of mass (points from center of mass to two ends), if we represent it with respect to Sol (points from Sol to two ends), we might be able to integrate them simultaneously!
