Show affiliationsA basic constraint to be satisfied by a Brans class I solution for being a traversible wormhole is derived. It is argued that the solution could be a wormhole analog of the Horowitz–Ross naked black hole. It is further demonstrated that the wormhole is traversible only 'in principle', but not in practice. Using a recently proposed measure of total gravitational energy inside a static wormhole configuration, it is shown that the wormhole contains the repulsive gravity required for the defocussing of orbits at the throat.
