Abstract Nuclear mass measurements and neutron matter theory tightly constrain the nuclear symmetry energy parametersJ,L,KsymandQsym. Corroboration of these constraints onJandLcan be found from measurements of the neutron skin thicknesses and dipole polarizabilities of neutron-rich nuclei. The experimental constraints on these parameters are compared with those obtained from consideration of astrophysical measurements of the neutron star radius, which we show is highly correlated withL. Attention is aimed at the recent PREX and CREX neutron skin measurements from Jefferson Lab, NICER neutron star radius measurements, and a new interpretation of the GW170817 tidal deformability measurement. We find joint satisfaction of PREX and CREX givesJ= 32.2 ± 1.7 MeV andL= 52.9 ± 13.2 MeV, in excellent agreement with neutron matter predictions ofJ= 32.0±1.1 MeV andL= 51.9±7.9 MeV.
