The question “How do you weigh a planet suspended in space without a cosmic scale?” seems absurd at first glance. Yet scientists have precisely calculated Earth’s mass at 5.972 × 1024 kg through ingenious physics experiments spanning centuries. Unlike calculating Earth’s diameter or circumference—measurable through geometry and astronomy—determining mass requires understanding gravitational interactions between Earth…
