What was the last planet found in the Milky Way?

As of October 2023, the most recently confirmed exoplanet in the Milky Way is TOI-700 e, discovered by NASA's Transiting Exoplanet Survey Satellite (TESS) in January 2023. It is located about 100 light-years away in the constellation Dorado and is notable for being in the habitable zone of its star, which could potentially allow for conditions suitable for life. However, many new exoplanets are continuously being discovered, so the status may change as new findings emerge.
