In your own words, describe the original properties of this proto-star/proto-planetary disk. 2. Then provide a full description in a clear, complete manner how the prevailing scientific theory explains this transformation. (remember to provide a clear, complete discussion!). 3. Finish up by describing the properties of the resulting structure (vaguely described above as a “central star, four similar inner planets, a band of ‘leftover’ planetesimals, and four similar outer planets”). 15 Points
