1998, Gliese 876 b: The first planet that orbits around the red dwarf star Gliese 876. It orbits closer to the star than Mercury is to the Sun. More planets have subsequently been discovered closer to the star.
Gliese 876 is the first dwarf star with a planetary system ever discovered. It contains three planets, including a terrestrial one with a mass 6-8 times that of the Earth.
This method is most sensitive to giant planets with large orbits. The Hubble Space Telescope was used in 2002 to make astrometric measurements to characterize the orbit of a previously discovered planet around Gliese 876b.
