Hypothetical moons are moons that have not yet been discovered, some hypothetical moons are false, due to being disproven to exist.

Here is a list of the Hypothetical moons.
Name of Hypothetical Moon | Parent Object | Distance from Parent Object | Diameter in kilometers | Reason Hypothesized | Disproven? |
---|---|---|---|---|---|
Hermes | Mercury | N/A | N/A | None, but turned out to be misinterpreted data from the star, 31 Crateris. | Yes |
Caduceus | Mercury | N/A | N/A | NASA claimed that this moon existed as an April Fools joke. | Yes |
Neith | Venus | N/A | Around 3026 km (¼ of Venus' diameter. | Reportedly sighted by Giovanni Cassini in 1672. | Yes |
Petit's moon | Earth | 11.4 - 3,570 km | N/A | First major claim of another moon of Earth made by French astronomer Frédéric Petit. | Possibly? |
Waltemath's moons | Earth | 1,030,000 - 427,250 km | 700 - 746 km | To explain the gravitational interactions of the Moon's orbit, and the cold spring of 1907, the may 1907 solar eclipse, and the so-called "Green Crescent moon" | Yes |
Bagby's Moons | Earth | N/A | N/A | A person named John Bagby thought he saw some natural satellites orbiting Earth, but these moons were not confirmed. | Yes |
Chiron | Saturn | N/A | N/A | Thought to be orbiting between Titan and Hyperion. | Yes |
Themis | Saturn | 1,456,456 km | Estimated to be 61 km | Reportedly found by astronomers. | Yes |
Chrysalis | Saturn | N/A | ~1,469 | To explain the formation of Saturn's rings. This moon was supposedly torn apart by the tidal forces of the planet. | No |
Varuna I | Varuna | 1300-2000 km | N/A | Reported during occcultation. | No |
Sedna I | Sedna | N/A | N/A | To explain Sedna’s slow rotation. Later disproven as better data said that the rotation was only 10 hours. | Yes |
Pallas I | Pallas | N/A | About 1 km | Occultation data suggested a satellite was orbiting Pallas. | Yes?[1] |
Pallas II | Pallas | 750 km | 175 km | In 1980, a large satellite was said to orbit Pallas, but was disproven with occultation data. | Yes |
Jebe | Hebe | 900 km | 20 km | After an occultation in 1977, a moon around Hebe was suggested by Paul D. Maley. Observations from telescopes have failed to detect a satellite, doubting its existence. | Yes |
Herschel's Moons | Uranus | N/A | N/A | To explain why Herschel saw four additional moons around Uranus. Later disproven. | Yes |
Metis I | Metis | 1,100 km | 60 km | Light curve data suggested a moon was orbiting the asteroid. Later observations and searches found no satellite. | Yes |
Amphitrite I | Amphitrite | N/A | N/A | Same reason as Metis I. | Yes |
