Perhaps.  But, I can authoritatively state that you don't WRITE it
well.

Are you saying if it moving away from the sun at Earth it CAN'T
outgas?

That wasn't YOU I responded to saying "I disagree. Given a reasonable
time interval, the trajectory and mass can be observed to almost total
accuracy."?  There is some other Joel Olson in this thread?  The two
of you should use your middle names to enable us to distinguish
between the two of you.

>You're saying its impossible?

Sure, it's possible.  If it isn't a comet or if it never outg*****.
