1. Collisions in Saturn’s Rings : Each of the particles in the

densest part of Saturn’s rings collides with another particle about

every 5 hours. If a ring particle survived for the age of the solar

system, how many collisions would it undergo ? 2. Orbital Resonances. Using data in Appendix E.2, identify the

orbital resonance relationship between Saturn’s moon Titan and

Hyperion. [Recall that an orbital resonance means that if one

moon’s period times X (where X is an interger) equals the other

moon’s period times Y (where Y is an interger)—then the moons are

said to be in an X :Y resonance. For example, if the orbital period

of one moon were 1.5 times the orbital period of another moon, 1.5

is 3 divided by 2, and so the moons would be in a 3 to 2 (3 :2)

orbital resonance.] 3. We have a Jupiter: Suppose that our Solar System never had

the planet Jupiter. Describe at least three ways in which a

Jupiter-less solar system would be different from our current solar

system. In each case, CLEARLY EXPLAIN WHY 4. Where comets come from: Explain in your own words how and why

there are two different reservoirs of comets. Be sure to discuss

where the two groups of comets formed and what kinds of orbits they

travel on.

– The age of our solar system is 4.6 billion years T = 4.6 xlo” yrs 1 year = 365×24 hr = 8760 hrs T = 4.6×109 x 8760 hrs T = 40.3 81012 hours – In saturn’s ring, panticles are collide with each other about every 5 hours. t= 5 hours so number of collision for time T is # Collisions – I 40.3×10!? = 8.06 x 1012 collis # collisions E 8.06×1013) (Pony).
