1	Dr. John Lewis	To stimulate a wider view of the issue of formation of planetary systems, perhaps the students can visit the The Extrasolar Planets Encyclopaedia Web site and read through the Extra-solar Planets Catalog to get an idea of how bizarrely different these systems can be. They list 135 planets of the 140 or so presently under discussion as candidates.
