Planetary Science: A new spin on Saturn
David J. Stevenson1
Abstract
Measuring the rotation of a gaseous planet is no easy task. For Saturn, do observations of its magnetic field — which indicate that it is spinning more slowly than thought — mark a revolution in our understanding?
According to the International Astronomical Union (IAU), Saturn rotates once every 10 hours, 39 minutes and 22.4 seconds.
- David J. Stevenson is in the Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, California 91125, USA.
