Abstract

The notion of spacetime symmetry is essential to describe gravitating physical systems like planets, stars, black holes, or the universe as a whole, since they possess, at least to good approximation, spherical, axial, or spatially homogeneous and isotropic symmetry, respectively. This article gives a quick overview over the known facts on spacetime symmetries in teleparallel gravity. The most general spherical, axial, or spatially homogeneous and isotropic tetrads in Weitzenb\"ck gauge are presented and a brief discussion about symmetric solutions of the anti-symmetric field equations in f(T,B,ϕ,X)f(T,B,\phi,X)-gravity is given.
