Jupiter LIX, provisionally known as S/2017 J 1, is an outer irregular satellite of Jupiter on a retrograde orbit. It was reported on June 5, 2017, via a Minor Planet Electronic Circular from the Minor Planet Center.[4] It is about 2 km in diameter.[3]
It is a member of the Pasiphae group. It has an average orbital distance of 24.1 million km, with an inclination of 144.7 degrees. Its period is 767 days.[2] It next comes to apojove (farthest distance from Jupiter) on 18 March 2026 when it will be 0.21 astronomical unit|AU (31 million km; 20 million mi) from Jupiter.[1]
