Abstract: We discuss classical closed string solutions in non-relativistic two-sphere target spaces. These classes of solutions closely relate to the GKP-type, spinning and pulsating strings for the relativistic case. We derive the string dynamics in each case and construct relevant dispersion relations, both from the string Newton-Cartan intrinsic sigma model and using a large speed of light expansion of relativistic Polyakov action. We further discuss construction and characteristics of exactly solvable Neumann-Rosochatius-like dynamical systems corresponding to strings in leading and subleading orders of the expanded Polyakov theory.
