I questioned my uncle on this. The model for calculating Isons mass was based research carried out on the Shoemaker levy comet by the Los Almos national laboratory doi:10.1038/370349a0. If you a not familiar with this work, they calculate the average comet density to be 50g/m3.

I think you mean .5g/cm3
Or 500 kg/m3

So a plausible density for Ison is probably more around .485 g/cm3 or 485 kg/m3.


I'm not certain of this, but these figures seem more realistic to me.

Well spotted, I correct myself in a post half way down the page as I could not edit the page.

Actually your correction was as follows:

"Sorry masses should have read 480g/m3 and 500g/m3"

Those aren't "masses", they are densities and they should have been in kg instaed of g, so it wasn't really a correction.
