How many candidates were reported detected via astrometry compared to the confirmed count of pure discoveries?

Answer

Nearly 9,700 candidates versus approximately a dozen confirmed

The data reveals a stark contrast between the sheer number of signals identified by astrometry and the highly verified confirmed discoveries. One paper reported identifying nearly 9,700 potential candidates that showed evidence of stellar wobble due to orbiting bodies detected via astrometric surveys. However, the rigorous, long-term validation required to confirm these subtle shifts as truly planetary—ruling out instrumental noise, stellar spots, or background contamination—drastically reduces the final number archived as unambiguous discoveries. As reflected in dedicated catalogs, the number of planets confirmed *primarily* through astrometric measurements alone stands at approximately a dozen.
