δ Gravity is a gravitational field model, where the geometry is governed by two symmetric tensors, gμν and gμν, and new matter fields (δ Matter fields) are added to the original matter fields. These new components appear motivated by a new symmetry, called δ symmetry. In previous works, the model is used to explain the expansion of the Universe without Dark Energy and use δ Matter as a source of Dark Matter. In this paper, we will developed an initial study of Schwarzschild geometry in δ Gravity to complement the Dark Matter analysis and introduce other phenomena. We will get a modified deflection of light produced by the sun, the perihelion precession and black hole solution.
