And since the EC will only work in the fantasy universe for the EU your model will never amount to something.
But still here we are!

Comets are rocky objects discharging in the solar wind!

Ice...

So comets are dirty snowballs in you fantasy world still, Lukraak_Sisser?

We stopped using that model a few pages back and NO new mainstream model has been put forward.

NO dirtysnowball = no mainstream model.

on the other hand...

11 CONCLUSIONS

The classical model of comets as dirty ice balls (Whipple 1950) has
focused most models of comets on ices.

The more we visit comets, the dustier they appear. With 67P’s dust-to-water ratio of 6 (and possibly larger), it is now necessary to spend much more time in modelling the non-volatile matrices with a modest content of ices inside.

Jean-Pierre Bibring proposes a new word naming this stuff,
‘organic(e)s’, where the modest content of ices (within brackets)
well summarizes the dominant non-volatile component.

Between the sizes of 0.1 and 1 mm, 99 per cent of the dust mass is in the
form of compact particles, denser than the nucleus.
This implies
that much of the nucleus mass is in the form of mineral aggregates
(silicates and sulfides), so that a better definition may be ‘mineral
organic(e)s’.

And I see you are a clever cookie, do you have a rational mainstream dirtysnowball explination for; "99 per cent of the dust mass is in the form of compact particles, denser than the nucleus."

When and using all the maths and gravity experiment data from the RSI to come up with
Quote:
For a range of compacted dust material density from 2000 to 3500 kg/m3, the porosity varies between 65% - 79% when the dust-to-ice mass ratio F nucleus for the nucleus body lies in the range 3 ≤ Fnucleus ≤ 7.

The nucleus is thus a highly porous very dusty body with very little ice.
Martin Pätzold

Which reinforces A'Hearn's statement
Quote:
our understanding has been evolving more toward mostly rock, particularly for 67P/C-G
So,
Quote:
Given that the 67P high friction coefficients are comparable, or even exceed, those found on Earth dry landslides (Legros, 2002), this implies
a mechanically rocky-type behaviour for the cometary material.

Our findings reject the idea that comets are fluffy aggregates, instead, they are characterised by consolidated surfaces.

What rock? Well that kind of ROCK, for starters

smectite clay; iron-containing compounds; carbonates, the minerals in seashells; crystallized silicates, such as the green olivine minerals found on beaches and in the gemstone peridot;

So, pretty good argument that comets ARE INDEED ROCKY objects!


As stated by the ELECTRIC COMET.
