What Planets Don’t Have Moons?
Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons. In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons.May 19, 2021
Why do planets not have moons?
Venus and Mercury are the only planets in our solar system with no moons. That’s primarily because they’re too small and too close to the Sun to retain a moon, and Venus’s motion is too unusual. The other planets and dwarf planets in our solar system have at least one moon, but Mars may lose one in 10-50 million years.
