Comets are the least altered bodies left over from the formation of our Solar System. Therefore, study of comets yields constraints on conditions when the planets formed. 

In this talk, Dr. Cochran will explain about the formation scenario for planets and what comets represent in that scenario. In addition, where the comets originally formed, where they currently reside and how an occasional comet comes into the inner Solar System to show off and be studied will be presented.

From 40 years of studying comets, we have developed information on their composition. However, the picture is not as simple as we would have hoped, and the complications will be shown.  Finally, Dr. Cochran will discuss some peculiar cases and give a coming attraction of an upcoming comet!

Please join us for what promises to be an interesting and informative discussion!
