I'm not precisely sure what to put for the composition, as the diagram shows:

COMET BURKE

COMPOSITION H. C. OH. CO.

CN. N2. H20. CO. H30.

COMA vs NUCLEUS 100,000 miles vs 15 mile

At least I think those are dots, might be really tiny numbers or something. For super pic, see: [1] - AJHalliwell 07:07, 20 Jul 2005 (UTC)

• 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)
