This cannot be explained solely by baryonic matter and dark matter. An additional component with negative pressure is needed to reproduce the observed acceleration.
On smaller scales, such as the Solar System itself or the Local Group, the effects of dark energy are not observable. In these regimes, gravity ultimately dominates the dynamics, keeping structures bound against dark energy. Gravitational attraction acts in opposition to the repulsive effect associated with dark energy. In the case of the Solar System or…
