Could a Comet Hit Mars in 2014?

Thanks

Yes he can! Kershaw was actually raised on the bayou in Cameron parish.

One of his first hits, 'Louisiana Man', pretty much describes his early childhood.

Is not ISON just a melt away from being nothing? No mass really to it at all?

I’ve seen estimates of 1 to 10km. Nothing official...

Just saw a post on ATS of a tweat attributed to Nick Howes of the Remanzacco Observatory stating that ISON's nucleus has been estimated to be approximately 20 km across.

That puts it well above average and should mean it will put on a great show this fall, if true.

Here’s the last performance from that old PBS special, called “Fiddlers Three” with Jean Luc Ponty, Itzhak Perlman and Doug Kershaw joining for the finale:

Yeah but it’s a virgin comet...

It’s just as likely to be a vapor trail of 100k miles and nothing else....as it passes near thanks to a few sunny rays..lol

Most of the fluffy stuff was removed when the sun went nuclear and from eons of solar wind. It'll be an amazing show if the nucleus is 20km in size, as the nucleus will contain 8,000 times the volume of a 1km comet.

And despite what officials are saying, if a breakup occurs at ISON's perihelion, it will be an even more amazing show, as surviving debris streams past the earth at 250,000 mph!

Hopefully at a safe 30 million km distance or more, since even the possibility of a really energetic breakup altering debris trajectories closer to the earth is slim, according to these same officials. lol

Amazing path of C/2013 A1:
