. CfA astronomer Scott Gaudi and his colleagues have solved the case of Sedna's missing moon. That distant solar system world (shown in this artist's conception) spins more rapidly than originally thought, rotating once every 10 hours. Although Sedna is unusual in many other ways, its rotation period is normal, meaning that no moon is required to slow it down. David A. Aguilar (CfA)
