Abstract

The recent fly-by of Uranus by the Voyager 2 spacecraft provided a singular opportunity to measure one of the fundamental but poorly known physical properties of the planet, its intrinsic rotation period. Earth-based photometric and spectroscopic estimates of the ‘atmospheric’ period vary greatly, with values ranging from 12 to 24 h (refs 1–4); estimates of the period based on the dynamical flattening of a rotating body range from 15 to 17 h (refs 5, 6). Here we use the Voyager planetary radioastronomy7 and magnetometer8 observations at Uranus to derive a period of 17.24 ± 0.01 h. The greatly improved precision of this measurement provides useful constraints on models of the planet's internal structure.
