  Using Keck/HIRES, we report abundances of 11 different elements heavier than
helium in the spectrum of Ton 345, a white dwarf that has accreted one of its
own minor planets. This particular extrasolar planetesimal which was at least
60% as massive as Vesta appears to have been carbon-rich and water-poor; we
suggest it was compositionally similar to those Kuiper Belt Objects with
relatively little ice.
