QUOTE {}In comparison, bulk silicate Mars reflects 27 ± 5% pebble-accreted material and 73 ± 5% Vesta-like planetesimals.
QUOTE {}Using Bayesian inference, we found that bulk silicate Earth is best reproduced by ≳75% contribution from two protoplanets formed via pebble accretion, supplemented by up to ~25% material from planetesimals that are compositionally akin t...
