Mass-radius relationships and constraints on the composition of Pluto. IIA model of Pluto's interior is presented based on new estimates of its mass within the range of possible masses. The model is consistent with the most recent observations by Arnold et al., and calls for a silicate-poor, H2O ice-rock bulk composition of Pluto. The results of the Charon-Pluto eclipses will lead to a more conclusive constraint to Pluto's bulk composition.
