Abstract We describe basic observational data regarding the 160-min oscillations of the Sun as well as the implications for helioseismology. The most acceptable theoretical interpretation seems to be a resonant interaction of gravity g-mode oscillations of the solar model with a slight modification to the equilibrium structure (with low heavy element abundance). It is noted also that there is significant 160-min commensurability over the solar system; e.g., spin rates of main and minor planets prefer, statistically, to be integer multiples of the 160-min period. The same period appears to be the most ‘characteristic’ period (in the range studied from about 110 to 830 min) for the distribution of orbital periods of close binary stars. Allowing for these facts various non-classical suggestions as to possible nature of the 160-min period are briefly reviewed.
