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
