Abstract
► As Mercury orbits the Sun, its rotation includes a physical libration. ► Earth-based radar observations give us details of this libration. ► Mercury's inner core, if present, may influence its libration. ► We show that a marginally better fit to observations is achieved when an inner core is present. ► Our results suggest an inner core larger than 400 km.
