Concepts of dark matter (DM) and dark energy (DE) are introduced. As for other anomalies we describe two ways to solve DM and DE problems, namely a conservative way when we have to find substances with DM and DE properties or we have to change a fundamental gravity law. We discuss constraints on DM concentration near the Galactic Center from apocenter shift data. We note that Solar system data put stringent constraints on alternative theories of gravity.
