Jovian moon
S/2003 J 24 (temporarily designated EJc0061) is a moon of Jupiter, discovered by Scott S. Sheppard et al. in 2003. It was independently found by amateur astronomer K Ly, who reported it on June 30, 2021. It was formally announced on 15 November 2021 in the MPEC.
Ly had previously recovered four "lost" moons of Jupiter in 2020: S/2003 J 23, S/2003 J 12, S/2003 J 4, and Jupiter LXXIII.
Based on 90 observations with an absolute magnitude (H) of 16.7, the moon is about 2–3 km in diameter.
S/2003 J 24 orbits Jupiter at an average distance of 23,088,000 km (0.15433 AU) in 715.4 days, at an inclination of 162° to the ecliptic, in a retrograde direction and with an eccentricity of 0.25.
It belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 million km and at an inclination of about 165°.
This brief starts where responsible research should: with the source description of “S/2003 J 24” as jovian moon. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as jovian moon. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 3, 2026. The linked authority identifier is Q107643667. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2003, 2021 and 2020.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
