Re: [meteorite-list] Observed lunar meteorite impacts (distribution)

2008-05-22 Thread Chris Peterson
Most of these explosions were captured during meteor showers. I'd guess the uneven distribution simply reflects where the imagers were looking at those times, and possibly the FOV of the imaging systems. Given an average phase of 50%, you'd expect most of the recorded hits to be towards the

Good point Larry. But I can't understand why people are still carefully distinguishing between comets and Asteroids?, I think by now we can assume they are basically one and the same, and not some exotic different species. To me it's just that some rocks are more 'wet and oily' than others...

Hi Mark: It comes down to location, location, location. Where did they from? Where did they end up after the the Solar System settled down? How did they get here? Add to this the fact that there are cometary asteroids, objects in the asteroid belt that seem to have cometary behavior. Yes, it is

I don't, personally, see it as a hard distinction. The labels are more for convenience - comets tend to be 'wetter and oilier', and more often are in eccentric orbits. Asteroids tend not to exhibit coma/tail because in a more stable orbits, they would either have lost most of their

Yes, Agreed the labels are useful, but isn't it time to have a (in a Pluto-planet style controversial type way! ;) reclassification of names debate? 'Asteroid' usually means something in the asteroid belt. 'Comet' means, hmm what exactly does comet mean? - Ok yes an object on eccentric orbit

There are clearly two very distinct populations of objects, which have very different properties. Comets originate in the outer edge of the Solar System, and ices account for a significant proportion of their entire mass. Very few ever make it to the inner system, and when they do, they can

Yes as I say you can label them, but I still wouldn't say the differences where 'very distinct'.. juries still out on that one. I wouldn't mind betting there are quite a few 'icy asteroids' out there too... After all: we know little about composition. A burned out comet may or may not be

It's a simple case of the terminology being outdated. The term comet dates back to Aristotle and the name means star with hair in Greek. A lovely term that a child could sketch. The term Asteroid is much more recent (19th Century). The word means star shaped probably because that's how they
