Two New Moons of Jupiter Discovered

Jupiter

In the hunt for a new massive planet beyond Pluto (sometimes called Planet X), DTM staff scientist Scott Sheppard has been continuing his survey of the night sky with David Tholen (University of Hawai’i) and Chadwick Trujillo (Northern Arizona University) looking for very distant objects in the outer solar system. During this search, Sheppard and his team pointed their telescopes near Jupiter and discovered two new, mile-wide, moons of Jupiter, S/2016 J 1 and S/2017 J 1 (“S” for satellite, “J” for Jupiter), both announced in early June of 2017.
