What Is the Name of Venus's Moon?
Venus has no confirmed natural satellite. As of the latest public data, Venus remains one of the few planets in the solar system with no known moon, a fact consistently reported by NASA and planetary science databases NASA Solar System Overview.
The idea of a Venus moon has a long history, but modern observations have set strict upper limits on any such object. Current rankings of planetary moons place Venus at zero confirmed moons, alongside Mercury NASA Planetary Data.
Historical Claims and Observations
Early Reports of a Venus Satellite
In the 17th century, astronomers such as Giovanni Cassini and later observers reported a faint object near Venus, sometimes called "Neith." These sightings were later attributed to background stars, asteroids, or observational artifacts Forbes Science.
Modern surveys using high-resolution telescopes and spacecraft have found no evidence of a natural moon orbiting Venus. The planet's slow retrograde rotation and thick atmosphere make satellite capture and retention unlikely Space.com.
Why Venus Has No Moon
Orbital Dynamics and Capture Difficulty
Venus's proximity to the Sun and its dense atmosphere create strong tidal forces and atmospheric drag, making it difficult for a natural satellite to remain in a stable orbit over long timescales.
Studies of exoplanet systems and solar system dynamics rank Venus among the least likely terrestrial planets to host a moon. Current models show that any temporary captured object would quickly decay or be ejected SpaceX Updates.
