How was the Saturn-like planet TVLM513B discovered?

TVLM513B was discovered by astronomers who detected it through a wobble in its star's motion, caused by the planet's gravitational pull. This marks the first time this detection technique was successfully employed using radio telescope observations, specifically the continent Wide Very Long Baseline Array. This method is typically used for detecting Jupiter-like planets in distant orbits from stars, making this discovery particularly significant. TVLM513B orbits a small, cool star approximately 35 light years away from Earth.
