S/2003 J 10是顆直徑約為2公里,在大約700天內的週期圍繞木星運行,平均距離為22,700百萬米,與黃道的傾角為164°,方向為逆行,偏心率為0.34。

它似乎屬於加爾尼群

但自2003年被發現以來,這顆衛星就再也沒有出現過,現時被認為是遺失的衛星[5][6][7][8]

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.
