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
