Hi all -
I suppose that when we start to get decent IR images, this will be used to
explain the dark comets, i.l. the dead comet fragments. Rationalizations work
in strange ways

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
How many beautifully black and fully fusion crusted meteoroids and
asteroids are floating around out there in space?
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 be
Hi Eric:
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

A fusion crust is formed by the rapid melting and rapid resolidifying of the
meteoroid, caused by heat generated by a meteoroid
Hmmm... ;)

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 ).
I'm simply provoking

You can make wild guesses, but when you aren't even sure of the order of

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

the Great Fireball is a meteoroid with fusion crust.

Good points on the production and destruction rates.
Do we know how many meteoroids crash into the Sun or other planets? The
moon is a good example to look for a number of impacting meteoroids, but
it doesn't say how many will graze any given planet though. Unless of
course you're able to

thank you. This is a point I tried to make a week or so ago. Someone commented
that there is a lot of guessing??? That is the understatement of the year. Most

I agree with you, but isn't that assuming that all things are equal
across the globe? They are not...

the most mistaken concepts in our hobby so time for another treatise on fusion
