Halimede is one of the known moons of the planet Neptune

Discovery: Halimede was discovered by the Voyager 2 spacecraft during its flyby of Neptune in 1989. Its discovery was confirmed in subsequent observations.

Name and Origin: The moon is named after Halimede, a Nereid in Greek mythology who was one of the 50 daughters of the sea god Nereus and the nymph Doris.

Physical Characteristics: Halimede is relatively small, with an estimated diameter of about 62 kilometers (39 miles). Its shape and surface features are not well-known due to limited observations.

Orbit: Halimede orbits Neptune in a prograde direction, meaning it orbits in the same direction as the planet's rotation. It is classified as one of the irregular moons of Neptune due to its eccentric and inclined orbit.

Grouping: Halimede is part of a group of irregular moons of Neptune known as the "Nereid group." This group consists of several small moons that have similar orbital characteristics and are believed to have a common origin.

No dedicated missions have been planned or conducted specifically to study Halimede. The Voyager 2 spacecraft provided valuable data during its flyby of Neptune, including limited observations of Halimede.
