We show combining nuclear mass data with experimental information from neutron skins, heavy ion collisions, giant dipole resonances and dipole polarizabilities, and theoretical calculations of neutron matter, lead to stringent constraints on the symmetry properties of the nuclear interaction near the nuclear saturation density. Furthermore, these constraints are remarkably consistent with inferences from astrophysical observations of neutron stars. The concordance of experimental, theoretical and observational analyses suggests that neutron star radii, in the mass range 1 M_sun - 2 M_sun, lie in the narrow window 11 km < R < 12 km.
