We examine the viability of Weyl conformal gravity as an alternative to thegeneral theory of relativity. By using the extended rotation curve of the MilkyWay and velocity dispersions of four globular clusters, we show that Weylgravity predictions without resorting to dark matter comply with observationsat the galactic scale. For the Milky Way, we demonstrate that the uncertaintyin baryonic modelling results a bracket of possible rotational velocities whichwell encompasses the diversity in rotation curve construction. Such diversitygenerally arises from differences in measurements of velocity anisotropyparameter, and the circular speed and Galactocentric distance of the Sun.Furthermore, we explore the ability of Weyl gravity to account for the inferredacceleration of Abell cluster 1689.
