I'm not precisely sure what to put for the composition, as the diagram shows:
- COMPOSITION H. C. OH. CO.
- CN. N2. H20. CO. H30.
- COMA vs NUCLEUS 100,000 miles vs 15 mile
- A closer look at the image indicates the comet measurements are in miles, not meters. I've revised the article and text above accordingly. --Aurelius Kirk 10:40, 18 February 2006 (UTC)
