"Discovery of Exceptionally Tiny Moon Around Uranus and Neptune"

Astronomers have discovered two tiny moons orbiting Neptune and one circling Uranus, bringing the total number of known moons around the two planets to 16 and 28, respectively. The new Uranian moon, possibly the smallest of its kind, is just 5 miles wide and takes 680 days to orbit Uranus. The brighter of Neptune's two new moons is provisionally named "S/2002 N5," while the fainter one is currently assigned the name "S/2021 N1." All three moons have egg-shaped orbits highly inclined to the plane of their respective ice giants, suggesting they were gravitationally seized later on.
