Missed the deadline for editing a post and this needs to be a separate post to show what insanity Sol88 is capable of.
Sol88 confirms his insanity that A'Hearn stated that comets are actual rocks by quoting A'Hearn stating that Tempel 1 had "snowbank" outer layers. Note that Sol88's deranged dogma is that even the surface of comets is rock.

Michael A'Hearn states that outer layers of comet Tempel 1 are "a snow bank", not rock
We already knew that Sol88 was spewing out insane insults of the deceased Michael Francis A'Hearn and all astronomers by Sol88 linking them with Sol88's demented dogma, etc.
and now Sol88 confirms his insanity
Sol88 is too cowardly to link to the paper and expose his delusions and insults:
Comets: looking ahead
It takes 1 brain cell to understand that "comets" is more than 1 comet! In astronomy "refractory" means non-volatile as opposed to volatile (not Sol88's insanity of actual rock).
