  • Abstract Approach images taken by the LORRI imaging system during the New Horizons spacecraft encounter have been used to determine the mean radii and shapes of Pluto and Charon. The primary observations are limb locations derived using three independent approaches. The resulting mean radii of Pluto and Charon are 1188.3 ± 1.6 km and 606.0 ± 1.0 km, respectively (2-σ). The corresponding densities are 1854 ± 11 kg/m3 and 1701 ± 33 kg/m3 (2-σ). The Charon radius value is consistent with previous… CONTINUE READING
