Detailed explanation-1: -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.
Detailed explanation-2: -Mercury and Venus Neither of them has a moon. Because Mercury is so close to the Sun and its gravity, it wouldn’t be able to hold on to its own moon. Any moon would most likely crash into Mercury or maybe go into orbit around the Sun and eventually get pulled into it.
Detailed explanation-3: -Mercury has no moons. The planet’s close proximity to the Sun makes having moons impossible, as the star’s strong gravitational pull would likely pull them out of the planet’s orbit.
