Thanks Rob! Great response. That pretty much sums it up for me and
answers just about everything I was curious about in that email.
You mentioned...

Just a smigen bigger than not enough?

Thanks Rob! Great

My ISP continues to lose much of my email else send them in huge batches.
Some additional points to what was discussed thus far:
Iron migration to the core of a heat building/holding sized body is a buoyancy
issue and gravity driven so long as the iron remains molten.
Accretion probably
There was a question regarding the sorting of elements and why for example
common chondrules had more iron than did Carbonaceous chondrites. The reason
for the difference also includes why we use isotope ratios to determine from
where a parent body probably formed within the solar system.
Hi Eric
You are correct in thinking that electrostatics causes the initial clumping.
The early sun would have been extremely energetic and X-ray and UV radiation
would produce electro static charging of small particles.
Once they begin to clump to a sufficient size, they will attract particles
Hi all,
I love asking questions because I learn cool stuff! ;) How bout these...
How long does the formation of meteoroid bodies and larger asteroids take?
How does the iron migrate to the core?
Do all large asteroids consist of an iron core surrounded by lighter
materials further towards
How long does the formation of meteoroid bodies and larger asteroids
take?
I really don't know, but gonna throw out a guess. I'm assuming that in the
beginning of star and planet formation, there is a lot of dust around. I
recall an experiment aboard one of the Shuttles or space station
Thanks for the responses thus far...
I've studied lots of material and scientific papers on accretion, but
still have some questions. The gravity explanation is great, but it's a
little vague. I want to know what causes it I guess at the molecular
level. What physical forces and interactions
Hi Eric,
I'll take a stab at a few of your questions:
How long does the formation of meteoroid bodies and larger asteroids take?
This is not an easy question, as there were many processes at work during
the early solar system -- some constructive (gravitational/electrostatic
clumping), some
