'''{{nowrap|S/2003 J 4}}''' adalah [[satelit alami]] [[Jupiter]]. Satelit ini ditemukan oleh tim astronom dari [[Universitas Hawaii]] yang dipimpin oleh [[Scott S. Sheppard]] pada tahun 2003.<ref>[http://cfa-www.harvard.edu/iauc/08000/08087.html IAUC 8087: ''Satellites of Jupiter'']{{dead link|date=January 2018 |bot=InternetArchiveBot |fix-attempted=yes }} 2003 March 4 (discovery)</ref><ref>[http://cfa-www.harvard.edu/iau/mpec/K03/K03E11.html MPEC 2003-E11: ''S/2003 J 1, 2003 J 2, 2003 J 3, 2003 J 4, 2003 J 5, 2003 J 6, 2003 J 7''] 2003 March 4 (discovery and ephemeris)</ref>
{{nowrap|S/2003 J 4}} berdiameter sekitar 2 km, dan mengorbit Jupiter pada jarak rata-rata 23.571.000 km dalam 739,294 hari, dengan [[inklinasi]] sebesar 147° terhadap [[ekliptika]] (149° terhadap ekuator Jupiter), dengan arah [[retrograde]] dan dengan [[Eksentrisitas orbit|eksentrisitas]] sebesar 0,3003.
Satelit ini termasuk dalam [[kelompok Pasiphae]], yaitu kelompok satelit ireguler retrograde yang mengorbit Jupiter pada jarak antara 22,8 hingga 24,1 Gm, dan dengan [[inklinasi]] berkisar antara 144,5° hingga 158,3°.
Satelit ini belum terlihat kembali sejak penemuannya pada tahun 2003 dan saat ini masih dinyatakan [[Asteorid hilang|asteroid]].<ref>{{cite web |url=http://www.skyandtelescope.com/astronomy-news/outer-planet-moons-found-and-lost/ |title=Outer-Planet Moons Found — and Lost |last=Beatty |first=Kelly |date=4 April 2012 |website=www.skyandtelescope.com |publisher=Sky & Telescope |access-date=27 June 2017}}</ref><ref name=Jacobson>{{cite journal |last1=Brozović |first1=Marina |last2=Jacobson |first2=Robert A. |date=9 March 2017 |title=The Orbits of Jupiter's Irregular Satellites |journal=The Astronomical Journal |volume=153 |issue=4 |pages=147 |doi=10.3847/1538-3881/aa5e4d|bibcode = 2017AJ....153..147B }}</ref><ref>{{cite journal |last1=Jacobson |first1=B. |last2=Brozović |first2=M. |first3=B. |last3=Gladman |first4=M. |last4=Alexandersen |first5=P.
