'''S/2003 J 24'''（暫時命名為EJc0061）是一顆[[木星的衛星]]，由[[史考特·雪柏]]等人於2003年發現。它也由業餘天文學家凱利（Kai Ly）獨立發現，並於2021年6月30日報導了這一發現<ref>{{citation|title=Amateur Astronomer Discovers New Moon Orbiting Jupiter|work=[[Smithsonian (magazine)|Smithsonian]]|first=David|last=Kindy|date=July 22, 2021|url=https://www.smithsonianmag.com/smart-news/amateur-astronomer-discovers-new-moon-orbiting-jupiter-180978258/|accessdate=2023-04-14|archive-date=2021-07-23|archive-url=https://web.archive.org/web/20210723093527/https://www.smithsonianmag.com/smart-news/amateur-astronomer-discovers-new-moon-orbiting-jupiter-180978258/|dead-url=no}}</ref><ref>{{citation|work=[[Sky and Telescope]]|title=Amateur Astronomer Discovers New Moon of Jupiter|first=Jeff|last=Hecht|date=July 8, 2021|url=https://skyandtelescope.org/astronomy-news/amateur-astronomer-discovers-new-moon-of-jupiter/|accessdate=2023-04-14|archive-date=2021-09-08|archive-url=https://web.archive.org/web/20210908193821/https://skyandtelescope.org/astronomy-news/amateur-astronomer-discovers-new-moon-of-jupiter/|dead-url=no}}</ref>。它的發現於2021 11月15日在MPEC上正式宣佈<ref name="MPEC2021-V333">{{cite web |title=MPEC 2021-V333 : S/2003 J 24 |url=https://www.minorplanetcenter.net/mpec/K21/K21VX3.html |website=Minor Planet Center |access-date=16 November 2021 |archive-date=2021-11-16 |archive-url=https://web.archive.org/web/20211116032237/https://www.minorplanetcenter.net/mpec/K21/K21VX3.html |dead-url=no }}</ref>。<br />

{{nowrap|S/2003 J 24}}以715.4天的[[順行和逆行|逆行]]繞木星一周，平均距離為{{cvt|23088000|km|AU}}，相對於[[黃道]]的[[軌道傾角|傾角]]為162°，[[軌道離心率]]0.25。<br />
<br />
它屬於由不規則的逆行衛星組成的[[加爾尼群]]，此群繞木星的軌道傾角約165°，運行的距離在23到24 Gm之間。<br />
