Which Planet Has No Moons?
Mercury and Venus: Planets Without Moons
In our Solar System, all the giant planets—Jupiter, Saturn, Uranus, and Neptune—have moons. Even the smaller planets like Earth and Mars have natural satellites. However, there are two planets that stand out for their lack of moons: Mercury and Venus.
Mercury: The Closest Planet to the Sun
Mercury, the smallest and innermost planet in the Solar System, has no moons. One reason for this could be its proximity to the Sun. The Sun's strong gravitational pull makes it difficult for Mercury to capture and retain any natural satellites. Additionally, any potential moons would likely be destabilized by the Sun's gravity and either crash into Mercury or be pulled into the Sun.
Venus: Earth's Twin Without a Moon
Venus, often referred to as Earth's twin due to its similar size and composition, also has no moons. The reasons for Venus's lack of moons are less clear but could be related to its slow rotation and the planet's thick atmosphere. Some theories suggest that any moons Venus might have had could have been lost due to gravitational interactions with the Sun or other planets.
Conclusion
In summary, Mercury and Venus are the only planets in our Solar System that do not have moons. Mercury's lack of moons is likely due to its close proximity to the Sun, while the reasons for Venus's lack of moons are still a subject of scientific investigation.

Can moons have moons?
Submoons can survive only around large, wide-separation orbits, with few exceptions, such as Saturn's moons and Earth's Moon.
Discovery of five irregular moons of Neptune
Five irregular moons with diameters of 30 to 50 km have been discovered, indicating that Neptune may have captured these moons from heliocentric orbits.

Future space observatories could detect Earth-sized moons on Jupiter-sized planets by detecting their near-infrared spectral contrast, which could reveal potential habitats for life.
Resonant interactions and chaotic rotation of Pluto’s small moons
Pluto's small moons Styx, Nix, and Hydra are tied together by a three-body resonance, but perturbations by other bodies inject chaos into this stable configuration.

Highly CitedHabitable moons around extrasolar giant planets
Rocky moons orbiting extrasolar giant planets could potentially be habitable, if they orbit within the 'habitable zone' and have sufficient atmosphere and magnetic field strength.
Highly CitedMoon-packing around an Earth-mass Planet
The maximum number of moons that can stably orbit an Earth-mass planet depends on the assumed masses of the satellites, with up to 7 Ceres-mass, 4 Pluto-mass, and 3 Luna-mass moons possible.
Formation of Regular Satellites from Ancient Massive Rings in the Solar System
Most regular satellites in the solar system likely formed from ancient massive rings that once surrounded their planets, with Uranus and Neptune having had rings that disappeared to give birth to most of their regular moons.
Highly CitedFormation, habitability, and detection of extrasolar moons.
Extrasolar moons in the range of 0.1-0.5 Earth mass are potentially habitable, can form within circumplanetary debris and gas disks, and are detectable with current technology.
