S/2003 J 10

S/2003 J 10 is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard et al. in 2003.[2][3]

S/2003 J 10 is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 22,700 Mm in approximately 700 days, at an inclination of 164° to the ecliptic, in a retrograde direction and with an eccentricity of 0.34.

It seems to belong to the Carme group.

This moon has not been seen since its discovery in 2003 and is currently considered lost.[4][5][6][7]

We likely have all of the lost moons in our new observations from 2017, but to link them back to the remaining lost 2003 objects requires more observations a year later to confirm the linkages, which will not happen until early 2018. ... There are likely a few more new moons as well in our 2017 observations, but we need to reobserve them in 2018 to determine which of the discoveries are new and which are lost 2003 moons.
