Comments on “Two exact solutions to the general relativistic Binet’s equation”
In their recent manuscript He and Zeng claim that they have solved the general relativistic Binet’s orbit equation using the exp-function method and have obtained two exact solutions useful for theoretical analysis. We argue that the obtained solutions do not satisfy the original differential equation. Moreover, we present the alternative framework for the solution of the general relativistic Binet’s orbit equation.
