The trajectory will not change, because no external forces are involved. It's simple Newtonian mechanics. The center of gravity of the two parts will follow exactly the same trajectory as an intact comet would have done.

Really, then why did it break apart? Seems to me causality has to come into play. Also since there are reports that one of the parts is slowing some external force is clearly at work. I am not say this means doom. I am only pointing out the obvious.

Just because there is no external force doesn't mean internal forces aren't at play, two systems here. The center of mass will remain constant in the event ISON breaks itself apart, that is until each piece is then subject to the massive pull of the sun which will then completely change each segments trajectory.

If ISON, or any comet, broke apart on its own and had no sun or planet to be gravitationally inclined towards then it's segments would forever drift away from each other but the center of mass would remain constant.

If you have a 2Kg object break in half and its pieces fly off in opposing directions, and 1Kg reaches 100Km away from the other 1Kg then the center of mass for that system is at the 50Km mark in BETWEEN them; center of mass is no where near any of the pieces but where the WHOLE object WOULD have been.

To put it plainly, your wrong ac.

No, sir, I'm certain he is quite correct. The pieces will follow the same orbital path not 'fly off in opposing directions'.

You are correct hugh - straight line. the other poster with his analogy does not have ghis 2kg object flying through space at unbelievable speeds, being pulled by the gravity of the sun. If ison had dynamite at its heart and it blew in a massive fireball of power, it still wouldnt move anywahere but the path it is already on!

COMET C/2012 S1 (ISON) update November 16, 2013 from CBET 3715
H. Boehnhardt, C. Tubiana, N. Oklay, and J. B. Vincent, Max Planck Institute for Solar System Research, Katlenburg-Lindau; and U. Hopp, C. Ries, M. Schmidt, A. Riffeser, and C. Goessl, Astronomical Institute, Ludwig Maximilian University, Munich, report the detection of coma wings in Laplace-filter-processed CCD exposures of comet C/2012 S1 obtained with the 0.4-m telescope of the Mt. Wendelstein Observatory on Nov. 14.16-14.21 and 16.16-16.21 UT. The arclet-like wings appeared in opposite direction from the nucleus at position angles 15 and 195 deg on Nov. 14 and at p.a. 25 and 205 deg on Nov. 16. The coma wings extended straight from the nucleus for about 4700 km on Nov. 14 and 13500 km on Nov. 16 on either side of the extended radius vector and continued in streamers of the plasma tail. No coma wings were found in similar exposures obtained on Nov. 13. The coma wings suggest the presence of two or more sub-nuclei with individual expanding atmospheres in the overall cometary coma and may indicate recent nucleus splitting in the comet.
