Hi List!
Does anyone know if super-heavy elements are found in meteorites (even
in tiny amounts)?
Specifically, elements 112 to 119 or the transitionary metals between
104 and 111?
Best regards,
MikeG

All the transuranium elements are highly unstable so any trace amounts
of the super heavy elements are gone in just seconds to days. I think it
is a safe bet that there are none ever detected in meteorites.
Plutonium (Pu 94) and neptunium (Np 93) are the only transuranium
elements that have

Hi Goran and List,
What about the isotopes that reside within the island of stability?
Have any traces of them ever been detected? Those isotopes have
longer half-lives.
Best regards,

That is only theoretical half lives in most of the cases. The only
reference I have seen to it is atom number 114 with a half life of 2.6 s
and hints of an isomer of 114 with a half life of 60 seconds. Total
number of atoms 114 observed so far is only 80.
They are called stable but that is
Hi Sterling,
Looking at thes pictures, Lucretia does look smooth with the exception of a few
small (more recent) craters near the top.

Hi List:
I was wondering if it is know what meteorite(s) is from (or was created) at the
farthest point from Earth? I know they come from the asteroid belt and perhaps
from comets, but wouldn't it be really neat to have a meteorite that was formed
or (from) the farthest distance from Earth
Hi Greg.
You probably will not be able to get a definitive answer to this one. Meteorite
parent bodies are from asteroids and the most likely mechanism to inject
asteroids and their fragments into orbits that intersect the earth is
perturbations by Jupiter. This places most asteroidal
It's not the atomic number of a hypothetical
superheavy element that matters so much as
the number of neutrons and protons in the
nucleus.
Particles are forced to assemble in shells
according to their quantum properties. Electrons
assemble in shells, too. Helium with 2 electrons
has filled the
Hi Greg S., Richard, List,
Greg's question about the furthest known celestial body from which we
have a meteorite is very interesting! And it brings up another very
interesting question related to distance...
If we're not sure of the furthest asteroid or comet we've got meteorites
from, can

Hello Meteorite Fans,
We can't wait until you see the August issue of Meteorite Magazine because it
looks great! We just finished with the proofs and very soon it will be off to
the printer and into your mailboxes.
The redesign will be an ongoing process and we are counting on everyone to
Hi Maria, Larry, Nancy, and List,
Great job with getting the magazine setup for PayPal. That is a long
overdue positive development. I'm sure it will help increase the
subscriber base by giving people another payment option. :)
This reminds me, I let me subscription lapse and need to renew it.
I didn't write that.:) (inside joke)

Hi List,
The new Egyptian iron is now official and in the Met Bulletin
database. Notice the TKW! 1.6 metric tons! That is a lot of
fragments.
Also notice the classification type - iron ungrouped. Not ataxite.
Although the write-up does say the meteorite shows an ataxitic
structure.
Wow, thats quite a bit of material!
anyone have a small 5-10g sample they would be interested in trading?

Mike, Greg, All,
Just 1.6 tonnes? It's a 40 meter crater. Use some logic/physics.
Carancas made a 40 *foot* crater. The low estimates of its mass were
in the 2-3 tonne range. This crater is three times the diameter...
The amount that's there is going to be a lot more than 1,600 kg. I'd
guess
Listees,
Just letting everyone know that I have some more of the famous Illinois

Eric, List, all,
Asteroids are traveling at super high velocity when they impact...
The most common collision in a group of objects with similar
orbits is with two objects with similar orbits. Oh, yes, in the
movies it's always something that comes racing out of far

I've had the pleasure of handling and cutting some of this material,

have ever seen - in person or in photos. It ranks up there with
Plutorano and Shirokovsky. Even though the material is
non-meteoritic, I am

Hello Everybody,
My name is Gabriel and I'm new here in this list. I'm meteorite collector from
Brazil and I'm looking for a piece or a fragment of the Marília Meteorite, a
low TKW Brazilian meteorite.
Please, you have something to offer of this meteorite, contact me in the follow
e-mail:
Maria,
Thanks for the info. You are always on top of things and have all the
pertinent information available and at hand.
I do have one question. Since you aren't able to accept farm animals in any
form and I did want to pay with 3 cows or 6 lambs, then would you be willing
to trade 2 dogs
Brian,
If you turn those cows and lambs into steaks, chops, racks and legs, I'll be
more than happy to take them off your hands and pay for your subscription!
