'''Mab''' is an [[inner satellite]] of [[Uranus]]. It was discovered by [[Mark R. Showalter]] and [[Jack J. Lissauer]] in [[2003]] using the [[Hubble Space Telescope]].<ref name="IAUC8209">{{

Because the moon is small and dark, it was not seen in the heavily scrutinized images taken by ''[[Voyager 2]]'' during its Uranus flyby in [[1986]]. However, it is brighter than another moon, [[Perdita (moon)|Perdita]], which was discovered from Voyager's photos in [[1997]]. This led scientists to re-examine the old photos again, and the satellite was finally [[recovery|found]] in the images.<ref name="Showalter"/>
Liña 144 ⟶ 98:
Mab is heavily [[perturbation (astronomy)|perturbed]]. The actual source for perturbation is still unclear, but is presumed to be one or more of the nearby orbiting moons.<ref name="Showalter"/>
Mab orbits at the same distance from Uranus as [[R/2003 U 1]], a newly discovered dusty [[planetary ring|ring]]. The moon is nearly the optimal size for dust production, since larger moons can recollect the escaping dust and smaller moons have too small surface areas for supplying the ring via ring particle or [[meteoroid]] collisions.<ref name=mabchaos>{{

Following its discovery, Mab was given the temporary designation '''S/2003 U 1'''.<ref name="IAUC8209"/> The moon is also designated '''Uranus XXVI'''.<ref name="Gazetteer"/>
