We investigate stationary rotating closed Nambu-Goto strings in<br />
five-dimensional flat spacetime. The stationary string is defined as a<br />
worldsheet that is tangent to a timelike Killing vector. Nambu-Goto equation of<br />
motion for the stationary string is reduces to the geodesic equation on the<br />
orbit space of the isometry group action generated by the Killing vector. We<br />
take a linear combination of a time-translation vector and space-rotation<br />
vectors as the Killing vector, and explicitly construct general solutions of<br />
stationary rotating closed strings in five-dimensional flat spacetime. We show<br />
a variety of their configurations and properties.
