# Astronomers discover 'super weird' object: Could be the first confirmed exomoon This system 72 light-years away challenges our solar system's definitions. - **Source:** [Popular Science](https://brifing.si/source/cc3d313a-759c-4802-b881-fc8585f35ef9) - **Published:** 2026-07-22 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/b4dc9420-f8de-48f0-9b69-5de3e9947fee ## A system unlike our solar system Astronomers have discovered a 'super weird' object in the CD-35 2722 system, 72 light-years away. The system consists of a brown dwarf and a Jupiter-mass object orbiting it. This structure defies traditional 'planet' and 'moon' definitions, pushing astronomers to develop new classifications. ## Brown dwarf and its mysterious companion At the system's center lies a star half the sun's mass. Orbiting it is a brown dwarf 30 times more massive than Jupiter. But the real intrigue is the Jupiter-mass object orbiting the brown dwarf. Is this a moon, or something else entirely? ## Potential exomoon candidate Researchers believe this object could be an exomoon (extrasolar moon). While over 6,000 exoplanets have been discovered, no exomoon has been definitively confirmed. This discovery could be a first in astronomical history. ## Classification challenges Our solar system's clear categories fall short with this discovery. According to Alice Zurlo, the lines between 'star', 'planet', and 'moon' are blurring. The object's massive size makes it vastly different from traditional moons. ## Scientific semantics While astronomers lean toward calling it a 'moon', Kevin Hoy notes it's nothing like the small, rocky moons in our system. His 'third wheel' analogy highlights the system's uniqueness. More observations are crucial to solving this cosmic mystery. ## A milestone in astronomy Zurlo calls this discovery 'a breakthrough'. Confirming this exomoon candidate could open new chapters in understanding cosmic diversity. The study, published in Nature, has generated significant excitement in the astronomy community. ## Sources covering this story - https://www.popsci.com/science/first-confirmed-exomoon/ — --- _Summary written by Brifing from the original reporting.
