Satellite communications emerged as a promising extension to terrestrialnetworks in future 6G network research due to their extensive coverage inremote areas and ability to support the increasing traffic rate andheterogeneous networks. Like other wireless communication technologies,satellite signals are transmitted in a shared medium, making them vulnerable toattacks, such as eavesdropping, jamming, and spoofing. A good candidate toovercome these issues is physical layer security (PLS), which utilizes physicallayer characteristics to provide security, especially due to its suitabilityfor resource-limited devices such as satellites and IoT devices.  In this paper, we provide a thorough and up-to-date review of PLS solutionsfor securing satellite communication. We classify main satellite applicationsinto five domains, namely: Satellite-terrestrial, satellite-based IoT,Satellite navigation systems, FSO-based, and inter-satellite. In each domain,we discuss and investigate how PLS can be used to improve the system's overallsecurity, preserve some desirable security properties and resist popularattacks. Finally, we highlight a few gaps in the related literature and discussopen research problems and opportunities for leveraging PLS in satellitecommunication.
