Jupiter now has a total of 69 moons. Observations were made at observatories in Chile as well as the Subaru Telescope on Mauna Kea during the past year. The moons are small, only one or two km (about 0.6 to 1.3 miles) across. S/2016 J 1 takes roughly 1.65 years to orbit Jupiter, while S/2017 J 1 takes about 2.01 years to do the same.
