Taking this latest meteorite research into account, Boss revisited his

models beyond the initial collapse and into the intermediate stages of star formation, when the Sun was first being created, an important next step in tying together
Solar System origin
modeling and meteorite sample analysis.
Previous
modelling has shown that Jupiter and Saturn moved out of their initial orbits in the
early solar system, scattering nearby objects.
They

early solar system in which the gas that briefly surrounded the sun dragged Jupiter toward the sun, as appears to have happened to gas giants in most known exoplanetary
systems.
This finding ends a 35 - year - old debate on the possible presence of curium in the
early solar system, and plays a crucial role in reassessing
models of stellar evolution and synthesis of elements in stars.
Researchers who
model the
early history of the
solar system would like to know Phoebe's exact birthplace, but that's unlikely, Dalton notes: The outer planets migrated during that era and quickly scattered Kuiper Belt objects into new orbits.
Models predict that curium, if present, was in low abundance in the
early solar system.
Computer
models have shown that the
early solar system was a tumultuous billiards table, with dozens or even hundreds of planetary building blocks the size of Earth bouncing around.
These

early in the history of our
solar system, billions of years ago, before making its way to Earth.
Now, two new studies of Kuiper belt objects presented October 5 at a meeting of the American Astronomical Society's Division for Planetary Sciences in Pasadena, Calif., may reveal a crucial hole a prevailing
model of the

early history.
The team
modeled all the different types of impacts that might occur in an
early solar system, including their location, timing, size, and velocity.
``... we lack compelling scenarios leading to the origin of iron meteorites...
Early solar system collisions have been called upon to excavate this iron [from the cores of the largest asteroids], although numerical impact
models have found this task difficult to achieve, particularly when it is required to occur many dozens of times, yet not a single time for asteroid Vesta.»
