The James Webb telescope incurred a micrometeorite impact even though NASA engineers planned for these events:(see NASA Blog website)
With the intense gravitational field of the sun acting on a fragment broken off Mercury by an impactor it is unlikely that this fragment would find its way to Earth.
Any references regarding the Mercury to Earth orbital ballistic scenario is welcomed.

Yes, I do know that article. And it vaguely looks like Mercury, but any fragment knocked off Mercury would fall into the Sun and not away from it. The Sun is like a giant magnet in the middle of the solar system. |

TKW updated. It changed from the last post of this meteorite, and cut-and-paste, and Idiot Programmer ™.
The article linked to above, dated 29 June 2020, states:
Comparing data from the Messenger spacecraft, Professor Anthony Irving of the University of Washington determined that the NWA 7325/8409 meteorite pairing has a composition consistent with that of the planet in our solar system closest to the Sun, Mercury, which Messenger has been orbiting since early 2011. |

Regardless, it's very interesting material. I have a 4 gr piece of pair NWA 14578. Thanks for the great picture |

According to Dr. Tony Irving, who did the classification, it is not, it cannot be from Mercury. And the TKW is 434g. |
