The near horizon geometry of extremal black solutions plays an important rule and gives some information about the solution. In this thesis we study some properties of rotating solutions of five dimensional gravity. As a five dimensional supersymmetric solution with one rotating coordinate, we investigate the 5D supersymmetric black ring. We explore the enhancement of supersymmetry in the near horizon of 5D supersymmetric black ring and derive the associated superalgebra. Then we derive the macroscopic and microscopic entropy of this solution by using entropy function formalism and c-extremization approach respectively and show these results are in agreement. We justify our results by using Kerr/CFT approach. In the next step we study the generalization of Kerr/CFT approach to five dimensional rotating extremal black holes with two rotating coordinates. At the end we confirm our results by reducing the rotating extremal 5D solutions to 2D effective theory.
