Summary
Current modeling efforts say:
- The Earth may have taken as long as ~100Myr to form.
- Depends on things like the mass of the disk and the orbits of Jupiter and Saturn.
- However, some of its building blocks probably differentiated is <105 yr, but some very late.
- These building blocks came from all over the inner Solar System.
