An Anomalous Basaltic Meteorite from the Innermost Main Belt

摘要: Triangulated observations of fireballs allow us to determine orbits and fall positions for meteorites. The great majority basaltic meteorites are derived from the asteroid 4 Vesta. We report on a recent that has orbital properties an oxygen isotope composition suggest distinct parent body. Although its orbit was almost entirely contained within Earth’s orbit, modeling indicates it originated innermost main belt. Because meteorite body would likely be classified as V-type asteroid, precursors unrelated Vesta may reside in inner This starting location is agreement with predictions planetesimal evolution model postulates formation differentiated asteroids terrestrial planet region, surviving fragments concentrated
