Thanks.
They're still hung up on collision only/impactor only derivation of meteorites but at least they're learning someting new (to them)

Thanks.
http://arxiv.org/abs/1502.02361Some asteroids eject dust, producing transient, comet-like comae and tails; these are the active asteroids. The causes of activity in this newly-identified population are many and varied. They include impact ejection and disruption, rotational instabilities, electrostatic repulsion, radiation pressure sweeping, dehydration stresses and thermal fracture, in addition to the sublimation of asteroidal ice. These processes were either unsuspected or thought to lie beyond the realm of observation before the discovery of asteroid activity. Scientific interest in the active asteroids lies in their promise to open new avenues into the direct study of asteroid destruction, the production of interplanetary debris, the abundance of asteroid ice and the origin of terrestrial planet volatiles.
-Not weird if you have a correct theory about asteroids and comets (ie there are only asteroids, comets are asteroids that electrically discharge, asteroids can have varied compositions depending from which parent body they originated, they are planet debris)New research suggests the "rock comet" is weirder than previously thought.
- metals to goo, maybe Teddy, maybe, need to visit the asteroid first. If metal maybe it is blue because it has an oxide layer, oxide layers are caused by electricity...It's a weird blue asteroid that created the Geminids and gets so hot that metals on the surface turn to goo,Teddy Kareta
- a hintodd asteroid, which sometimes behaves like a comet by releasing a dusty tail when it passes close to the sun
He says they found it to be even more enigmatic than expected.
-Sure, and they will find many more surprises.they discovered Phaethon is darker with a more uniform surface than previously though
Thx Nick that is a longer article.nick c wrote:An asteroid that behaves like a comet! So it is an asteroid on an highly eccentric orbit.

Yes ,it was a cometary asteroid when electrically active; when it is not, it is 'just' an asteroid.it's been cooked through and turned off and it just looks like a rock
