We model the velocity dispersion of the ultra-diffuse galaxy NGC 1052-DF2using Newtonian gravity and modified gravity (MOG). The velocity dispersionpredicted by MOG is higher than the Newtonian gravity prediction, but it isfully consistent with the observed velocity dispersion that is obtained fromthe motion of 10 globular clusters.
