Fig. 1: Bulk Ne isotopic composition of Bennu samples (OREX-800032-102, -103, -104 and -105) compared with Ryugu and CCs.

a,b, Neon three-isotope plot (a) and restricted isotope ratio range plot (b). The Ne isotopic composition of a sample represents mixing between solar wind (SW), cosmogenic, phase Q (Q) and presolar (HL, R/G) components of Ne in varying proportions, as well as terrestrial air. The black dashed lines represent the mixing lines between these components. The pink dashed box in a denotes the bounds of b. CCs are abbreviated as follows: CI, Ivuna type; CM, Mighei type; CR, Renazzo type; CO, Ornans like. See Methods for sources of non-Bennu data. Error bars represent 1σ measurement uncertainties.
