Exomoon
3 reportsExomoon is an astronomical object studied through its light, motion, composition, environment, and population context. Researchers test interpretations with mass estimate, chemical abundance, and object classification, while incomplete records, model assumptions, and measurement limits constrain certainty.
The public record for Exomoon is read through physical structure, while also considering environmental interactions and population context. The strength of statements about physical structure depends on how well multiwavelength observations is supported by distance or orbit estimates; confidence is limited by the fact that limited viewing geometry and indirect measurements can leave competing explanations.

Simulations Reveal Moon May Have Formed in Hours After Giant Impact
New computer models suggest the Moon could have assembled rapidly from debris after a collision between early Earth and a Mars-sized body, with the timing and temperature of the impact playing a critical role
Possible Exomoon Candidate Challenges Definitions in Distant Star System
Astronomers using the Very Large Telescope have detected a moon-like object orbiting a brown dwarf in the CD-35 2722 system, raising questions about how to classify such bodies beyond our solar system
Giant Exosatellite Discovery Redefines Boundaries of Planetary Systems
Astronomers have identified a Jupiter-sized exosatellite orbiting a brown dwarf, itself in orbit around the star CD-35 2722. The finding, made using high-resolution spectroscopy, challenges current definitions of moons and planets.
