All of that is somewhat fact based, but how does CME's effect orbital trajectories
Coronal mass ejections reach velocities between 20km/s to 3200km/s with an average speed of 489km/s, based on SOHO/LASCO measurements between 1996 and 2003. The average mass is 1.6×1012kg.

Yet, here it was, somehow having increased its brightness by many hundreds of times!"

Within the past week the comet's brightness has declined by 50%, dropping a half magnitude between August 19th and 20th, according to Australian observer Michael Mattiazzo. (The comet's current location in western Virgo makes it virtually unobservable from northern latitudes.) Worse, images show Comet Elenin's bright core becoming elongated and diffuse — the telltale signs that its icy nucleus has either broken in two or disintegrated altogether.
One veteran comet-watcher who's not surprised is John Bortle. Four months ago, based on Elenin's performance to that point, he cautioned, "The comet may be intrinsically a bit too faint to even survive perihelion passage." And his words have proved prescient, as the fading continues (estimates are near 9th magnitude) and there's speculation that this object or its remnants might not be around much longer.
I guess all those pseudoscientific bloggers who predicted planet-altering encounters with a cosmic visitor bright enough to be seen in broad daylight will just have to find something else to worry about.
Rob McMaught reports that he can see only a smear and no central condensation using the E12 instrument, indicative that the comet is indeed disintegrating
I was in the understanding that this is the first trip to the inner solar system for this comet. Outgassing must have caused some big debris loosening, the big chunks would continue the sam trajectory as the comet before it broke up. We have no firm data of the alleged breakup. If it broke apart it would become LESS of a threat to earth. If solar heating broke it apart, what do you think earth atmospheric entry would do to it, especially as smaller pieces, when it's projected size as a whole would not create an Extinction Level Event?

Eureka! Elenin is Eleven and Nine right? That means there will be 9 to 11 comets coming our way. We will know more on 9/11 at precisely 9:11 pm. Eastern Standard I believe.
9 to 11 countries will come forth and admit that Elenin is in fact Nibiru which is in fact Nemesis which is in fact Planet X. X is also 10 which falls between 9 and 11! It's a mathematical code that after several days of studying I have concluded that 9 and 11 equals 20. That's as far as I've gotten.
I thought I should edit in I'm just kidding, ya know, for the more serious of you.
