Exploration of Neptune

Planets and Dwarf Planets

Neptune has been directly explored by Voyager 2, which visited in 1989. Since the mid-1990s, telescopes including the Hubble Space Telescope and the Keck telescope have studied the planet from afar. NASA, ESA, CNSA and independent academic groups have proposed scientific missions to Neptune, but as of 2026 no future mission to the Neptunian system has been confirmed.
