Hello all,
Could someone explain to me exactly how it was determined that certain
meteorites, like Tatahouine, originally came from Vesta ?
I appreciate the help.

Hi Andre,
Even before the NASA Dawn program, scientists had made a strong
connection between the HED meteorites and Vesta. The brief paper at
the link below gives a general explanation of the connection. In the
years since, Dawn has solidified that connection.
From the text :
Many lines of
Here is the abstract to the original paper published in Science in 1970.
Asteroid vesta: spectral reflectivity and compositional implications.
McCord TB, Adams JB, Johnson TV.
Abstract
The spectral reflectivity (0.30 to 1.10 microns) of several asteroids has
been measured for the first time.
Spectra comparison..see here...

I was out just before moon-rise trying to see if I could catch Vesta,
Ceres, and Jupiter together.
Just after I opened the shutter for a 6 exposure, I saw a meteoroid
streak across the sky apparent heading towards Ain. Very short and dim, I
hoped it'd be enough to expose at 1000ISO.
It did!
Yes, Sterling, Vesta is unique.
Besides all of the M asteroids in the asteroid belt (remnant cores of
differentiated asteroids), the iron meteorites we see today represent at
least 50 (I have seen a number exceeding 100) different differentiated
bodies. I think, that, while Vesta is clearly

Yes, but aren't the relatively few non-Vesta eucrites classified as
ungrouped achondrites or anomalous eucrites?(if not then they should

So I would like to think that there is already the notion that there

Keep in mind that there are now some non-Vesta originating eucrites

It is true that a few eucritic rocks are ungrouped. Ibitira is one example. It
is not surprising that basalts were erupted on a few distinct small bodies, 4.5

But all the diogenites display the same D17O as the (regular) eucrites, and no

Greetings Listers,
Like concentric ripples that eminate from the point at which a stone
hits water, the troughs on Vesta might be frozen shock waves from the
massive southern crater. This is only a not particularly educated
guess on my part but it is fun to try to explain their presence.
Happy
Vesta Spins!

Just a gentle request to resist the urge to parrot NASA's erroneous
