Comparison of the structural properties of Nube with those of other Local Group galaxies from McConnachie (2012, grey open circles), dwarf galaxies in Carlsten et al. (2021, green open squares and orange crosses), UDGs in Virgo from Mihos et al. (2015, red diamonds), UDG32 in Hydra I from Iodice et al. (2021, golden star), and Coma from van Dokkum et al. (2015, pink x). Although the central surface brightness is typical of other dwarf galaxies, the stellar mass and half-mass radius make Nube, at a distance of 107 Mpc, an extreme object, even more so than the UDGs in Virgo and Coma.
