Re: [meteorite-list] Allende parent body?

2011-04-15 Thread E.P. Grondine
Hi all - 

The work on magnetism in meteorite parent bodies is interesting, but I thought 
that Allende's parent body was cometary. 

If so, shouldn't the headline read: Comets found to have hard centers?

Or is this part of NASA's plan to have comets declared to be asteroids?

There is no particularly good reason to think that Allende (or any other 
meteorite) is cometary in origin.

*shameless plug* 

I've just added an article on Tunguska to my site:

http://historicfalls.com/2011/04/15/tunguska/

I know it's a slight cheat, not actually being an actual witnessed fall, but 
hey... What's the current thinking on the status of the impactor? Comet or 
Asteroid?

It goes without saying that IMHO,  ET's zapping us from 61 Cygni is not the 
likeliest answer...!
