We investigate the nature of the recently catalogued star cluster candidateFSR584, which is projected in the direction of the molecular cloud W3 and maybe the nearest globular cluster to the Sun. 2MASS CMDs, the stellar radialdensity profile, and proper motions are employed to derive fundamental andstructural parameters. The CMD morphology and the radial density profile showthat FSR584 is an old star cluster. With proper motions, the properties ofFSR584 are consistent with a metal-poor globular cluster with a well-definedturnoff and evidence of a blue horizontal-branch. FSR584 might be aPalomar-like halo globular cluster that is moving towards the Galactic plane.The distance from the Sun is approx 1.4kpc, and it is located at approx 1kpcoutside the Solar circle. The radial density profile is characterized by a coreradius of rc=0.3+/-0.1 pc. However, we cannot exclude the possibility of an oldopen cluster. Near-infrared photometry coupled to proper motions support thescenario where FSR584 is a new globular cluster in the Galaxy. The absorptionis A_V=9.2+/-0.6$, which makes it a limiting object in the optical and explainswhy it has so far been overlooked
