Abstract In this paper, we briefly review highlights of nonlocal de Sitter gravity based on the nonlocal term. √R − 2Λ F() √R − 2Λ in the Einstein-Hilbert action2 without matter sector. This nonlocal de Sitter gravity model has several exact cos-3 mological FLRW solutions and one of these solutions contains some effects that are4 usually assigned to dark matter and dark energy. There are also some other inter-5 esting and promising properties of this kind of gravity nonlocality. We also review6 some anisotropic cosmological solutions, and mention the corresponding nonlocal Schwarzschild-de Sitter metric.
