Abstract
⺠We analyze images obtained by the MESSENGER spacecraft during three flybys of Mercury. ⺠We obtain a new estimate for Mercury's mean radius of 2439.25±0.69 km. ⺠The mean equatorial radius and polar radius of Mercury are identical to within error. ⺠The residual topography along the Mercury limb has a dynamic range of 7.4 km and a root-mean-square roughness of 0.8 km.
