Interesting fact: The Moon's mass is about 1/81 that of Earth, which is why its gravity is much weaker.
The answer: The Moon has a mass of approximately 7.35 × 10^22 kilograms, or about 81 quintillion tons.
The Moon's mass determines its gravitational pull, which affects tides on Earth and the stability of Earth's axial tilt. Despite being Earth's only natural satellite, the Moon is much smaller and less massive, which results in about one-sixth of Earth's surface gravity. Scientists have measured the Moon's mass through spacecraft missions and observations of its gravitational influence on orbiting satellites and Earth.
