Table 1.
Planetesimal mass in M⊕ lost when Uranus and Neptune formed in the simulations by Izidoro et al. (2015).
| Initial total mass in embryos | Mean ejected mass | Hit the Sun | Hit the giant planets | Remaining mass |
|---|---|---|---|---|
| 60 | ~13 | ~1 | ~4–5 | ~41–42 |
| 30 | ~0.7 | ~0 | ~0.5 | ~29 |
Notes. The remaining mass must be used to form Uranus and Neptune (25.5–28 M⊕ in heavy elements) and the inner Oort cloud objects, like perhaps planet 9.
