Abstract: It is evident from the literature that the final fate of a collapsing star can be either a hidden or a visible singularity. The question then arises: How can these two distinct types of singularities be distinguished from one another? In this presentation, I will discuss the observational properties of compact astrophysical objects, with or without an event horizon. First, I will discuss the precession of test particles as they orbit these compact objects. Another aspect is the shadow cast by a black hole or a naked singularity. However, it is important to note that both precession and shadow properties often gives similar observational signatures, making them insufficient for a clear distinction. We will therefore explore how X-ray observations, particularly those involving accretion disk behavior and high-energy spectral features, can provide a more definitive method to differentiate between black holes and naked singularities. Concluding this, we will reflect on the open challenges that remain within this domain.
