How do the size and the surface gravity of earth compare to the moon?

Earth is significantly larger than the Moon; its diameter is about 3.9 times greater, and its volume is about 49 times larger. Consequently, Earth's surface gravity is also much stronger, being approximately 9.81 m/s², compared to the Moon's surface gravity of about 1.62 m/s². This difference in gravity affects how objects weigh less on the Moon than they do on Earth, contributing to the unique conditions experienced on the lunar surface.
