present an additional observational possibility: high-energy gamma rays and charged particles arriving from a direction tightly correlated with the centers of the Sun, Earth and other planets. Such novel signatures can be effectively probed with the powerful new generation of gamma ray telescopes.

The primary feature of secluded models of dark matter [@PRV] is a two-stage dark matter annihilation process: WIMPs annihilate first into metastable mediators, which subsequently decay into Standard Model (SM) states. This breaks the more-or-less rigid link between the size of the WIMP annihilation and WIMP-nucleus scattering cross sections. It has been shown that a small mass for the mediator allows for new phenomenological possibilities in the form of enhanced WIMP annihilation at small velocities [@AFSW; @PR] that may help to explain various astrophysical anomalies, e.g. the positron excess observed by PAMELA above 10 GeV [@pamela] and perhaps the unexpectedly hard electron spectrum observed by Fermi above a few hundred GeV [@FERMI]. Furthermore, a relatively small mediator mass kinematically removes heavy SM particles from the final state [@AFSW; @PR], reconciling these effects with the absence of any enhancement in the cosmic ray anti-proton signal [@pamela2]. The lifetime of the mediator is essentially a free parameter, limited only
