This is very interesting, jonesdave116.So,
67P C-G:
Aphelion: 5.68 AU
Perihelion: 1.24 AU
Eccentricity: 0.64
Period: 6.44 yr
Volume: 21.4 km^3
Mass: 10^13 kg
Density: 0.47 g cm^-3
4179 Toutatis
Aphelion: 4.12 AU
Perihelion: 0.94 AU
Eccentricity: 0.63
Period: 4.02 yr
Volume: 23.8 km^3
Mass: 5 x 10^13 kg
Density: 2.1 g cm^-3
Anybody see a problem here?
ETA:
Just for clarity, 4179 Toutatis is an S-type stony asteroid, consisting primarily of silicates.
Would you mind citing your source(s) for the orbital and physical parameters of 67P C-G and 4179 Toutatis? That way any reader can check your inputs, for themselves.
And has been pointed out - many times, by RealityCheck, Dancing David, and many others - a very large number of asteroids have 'comet-like' orbits, yet are not observed to have comet-like tails at any point in their orbits."The changing electrical stress on a comet is due to its highly elliptical orbit. The Sun has a weak radial electrical field. A comet spends most of its time far from the Sun and becomes adjusted to the voltage there. As it zips in for a quick fly-by of the sun, the voltage and charge density of the solar plasma changes rapidly, generating increasing electrical stress on the comet. When the electrical stress is high enough, the comet¹s plasma sheath lights up to form the classic cometary spectacle. The comet nucleus begins discharging and the resulting cathode jets sweep back to form a tail that is "blown" in a direction aligned with the Sun¹s electric field.
The same thing would happen to an object of any size on a cometary orbit through the Sun's electric field. If the Earth, which is a charged body, were on a cometary orbit, its magnetosphere would glow. Similarly, the objects forming the cometary knots of the Helix Nebula are responding to the strong electric field centered on the star outside the picture at bottom right."
A quote from Thunderbolts, in a previous post by Haig. My bold.
Then there are the comets which have orbits that would seem - from these quotes - to not be capable of becoming comets. For example, take the many comets with low e, in this list of comets ... 158P/Kowal-LINEAR, as one example, has an eccentricity of just 0.031!
Compare this with Mercury's, 0.206 ... by the logic in the EU quotes, Mercury should be a far more intensely active comet than 158P/Kowal-LINEAR.
Don't you just love DIRECT EVIDENCE?
