Have we found first exomoon? Strange object forcing astronomers to rethink what a moon is

Astronomers have found strong evidence for a massive object orbiting a brown dwarf.

This object behaves like a moon, circling another body which orbits a star.

Researchers are calling it an exosatellite due to its host's unusual nature.

This discovery marks a significant step towards confirming the first exomoon.

Future observations will determine its definitive classification and implications.
