Potential Exomoon Discovered Around Distant Gas Giant

12/1/2025

Summary

Story summary

A study published in Astronomy & Astrophysics reports a potential exomoon around the gas giant HD 206893 B, 133 light-years from Earth.
Researchers used astrometry to detect a secondary object of about 0.4 Jupiter masses, suggesting it could be the exomoon.
The finding requires further validation to confirm the exomoon.
The scientific community is increasingly interested in exomoons, with missions like NASA's Europa Clipper and Dragonfly targeting potential habitability.
