Hello Listers


I like to thank everyone that submitted their answers to me for this installment of POP QUIZ FRIDAYS. I would have to say the question I asked was kinda a hard one to research on the Internet, but if you some poking around, you would have found the answer. I would like to congratulate Regine P. being the first Lister to give me the correct answer because I didnt get a 7th Lister to send me the right answer. Regine won a free issue of Meteorite magazine from Feb 1998 which this issue has great images taken by Martin G. Horejsi, article about The Burnwell meteorite, Centerpiece about Melrose(a), and a visit about the old woman meteorite and not to mention other great articles to read about. I also have to add I enjoy looking at the AD's from 1998 and comparing them to now.


The question:

Please tell me how many F Class asteroids there are in the main belt.


The answer:

The rarity of F-class asteroids (only
4%, 92 of 2000 classified asteroids) and ureilites (only
0.6% of meteorite falls, 6 of 987) suggests that the
source region in the asteroid belt is a spectral anomaly.

The answer can be found in the Oct-Nov 2010 Maps issue in the article called

Almahata Sitta (=asteroid 2008 TC3) and the search for the ureilite parent body
