According to the passage, while scientists think they know the asteroid from which mesosiderites came, ----.
Meteorites offer glimpses of the earliest stages of
planetary formation. Stony-iron meterorites come in
two main classes: pallasites and mesosiderites, and
it was previously thought they may have had similar
origins. A new study, however, has revealed that
their oxygen isotope properties differ and that they
come from distinct places. Accordingly, the
characteristics of mesosiderites suggest they came
from the third largest asteroid, Vesta, which is the
target of the NASA Dawn Mission. On the other
hand, pallasites are made of mixed core-mantle
material from a disrupted asteroid, indicating that
extensive asteroid deformation was an integral part
of planetary enlargement in the early solar system.
