A week or so ago I asked a question about what a meteoroid would look
like floating through space. More specifically I wanted to know what
color a meteoroid might be "before" it actually hit Earth. Here's
another question.

>>How many beautifully black and fully fusion crusted meteoroids and

My guess is that there may be a lot of black meteoroids floating around in
space, but very few that are fusion crusted. To be fusion crusted, I would
imagine there would

A quick response to this:
1. Black, yes. Many asteroids are dark (reflect less than 10% of the light
that reaches them). This may be due to shock (black chondrites) or due to
the presence of carbon as in the carbonaceous chondrites (or comets for
that matter).
2. However, to the best of

Space weathering due to impingement by micrometeoroids and solar wind particles
is another important factor modifying an asteroid's reflectance spectrum. In
many cases more recent impacts on asteoids appear brighter than weathered
portions.

Yup it would be a guess, but doesn't science make guesses (hypotheses)
based on data and knowledge gained from data? Having said that, I think
it's safe to say there's more to it than meets the eye.
Would you like to take a guess? Not that I know the answer ( I do not ).

Again, that would depend on your definition of small. When figured as a
percentage of ALL meteoroids I would imagine that yes, logic would say
that the number of fusion crusted meteoroids is small when compared to
all the other meteoroids and asteroids out there. Since there are

I have thought what causes a fusion crust, but to be brief, I didn't explain
the obvious process of entry into an atmosphere and back out. To me, this
"skipping out" of the atmosphere is a relatively rare event. Most of anything
that enters the atmosphere in the first place burns up in the p

This grazing of our atmosphere would cause fusion crust. This means that
the Great Fireball is a meteoroid with fusion crust.
