Hello Jerry: Good summary! There are actually other compositional (spectral) classes of asteroids, but you hit on the main ones. While most C-asteroids are "wet," some appear to be dry (at least on their surfaces). Also, there are "wet" M-asteroids, which are clearly NOT metallic, but it is not y

Re: [meteorite-list] Observed lunar meteorite impacts hit 100

There is a large distinction between the classical comets and the classical asteroids. Comet Hale-Bopp or Huykatake could never be confused for an asteroid. On the other hand there are comets that are almost spent out such as P/Arend-Regeaux which at often times appears stellar like through even

Re: [meteorite-list] Observed lunar meteorite impacts hit 100

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 volatile

This got me thinking... some of the lunar impacts are being attributed to well-known meteor showers. Are there any good candidates for (earthly) meteorites which may be part of such showers, and therefore potentially once part of the presumed parent body? I guess candidate criteria would be ti
