Moore County

April's Meteorite of the Month is Moore County, an achondrite (eucrite-cm) meteorite that fell the evening of April 21, 1913, in North Carolina.

The Moore County fall was accompanied by a "rumbling and zooming" noise, with "no distinct explosions", according to eye witness accounts, and was recovered from a freshly plowed field near Carthage, North Carolina.

Moore County is a cumulate eucrite, part of the Howardite-Eucrite-Diogenite (HED) meteorite group. Members of the HED meteorite group are believed to have formed on the surface of asteroid 4-Vesta. According to radioisotope dating, the HED achondrites crystallized between 4.43 and 4.55 billion years ago.
