Facts from the source article.
Planetary system
Back in 1989, astronomers spotted a possible 416-day radial velocity signal hinting at a companion, but it was never verified. Later, TESS found a candidate transiting planet with an orbital period under a day.
By January 2023, that planet was confirmed as Gliese 806 b, and a second, non-transiting planet was detected through radial velocity. A third radial velocity signal remains unconfirmed. All known planets are super-Earths, and the inner transiting one is likely rocky.
