Astronomers Signal First Plausible Exomoon, Blurring Moon-Planet Boundaries

Using ESO's VLT CRIRES+ radial-velocity measurements, scientists report strong evidence for an exosatellite (a Jupiter-sized body) orbiting a brown dwarf in the CD-35 2722 system—a three-body setup that challenges Solar System definitions of moon and planet. If confirmed, it would be the first plausible exomoon detection and could accelerate future exomoon searches, though the terminology remains debated.

Weird exomoon candidate sparks debate on what counts as a moon

Astronomers analyzing the CD-35 2722 system, about 73 light-years away, report a moon‑like object orbiting a brown dwarf—an finding that could be the first exomoon or a case that forces a redefinition of what counts as a moon versus a planet. While the object is clearly moon‑like, the team stresses a definitive exomoon claim would require redefining established terms, since it orbits a body that itself orbits a star. The discovery, published in Nature, underscores the diversity of planetary systems and may be clarified further with observations from the upcoming Extremely Large Telescope (ELT).
