Crater 2 appears to be in alignment with the globular cluster Crater, the pair of ultra-faint dwarf galaxies Leo IV and Leo V, and the dwarf galaxy Leo II. The alignment seems to be statistically significant enough to suggest that the Leo-Crater group was once a more cohesive stellar system that has since dissipated into a stream of multiple stellar systems due to tidal disruption from the massive Milky Way galaxy.
This diagram shows absolute magnitude versus half-light radius, whereby dwarf galaxies that are satellites of the Milky Way are denoted by red open circles, dwarf galaxies that are satellites of the Andromeda galaxy are denoted by black unfilled triangles, and other nearby galaxies are denoted by gray crosses. Black dots indicate globular clusters of the Milky Way and grey dots indicate extended objects with half-light radii smaller than ~325 light years. Crater 2 is marked with a filled red circle. The black solid line and the black dashed line, respectively, correspond to the surface brightness levels of 31 and 30 mag/arcsec². Torrealba et al. (2016)
