Measuring the Earth’s Mass Through Its Gravity (351 words, 2 pages)

The only way we can measure a planet's mass is through its gravity, the way Earth's mass was measured. Since nobody ever visited other planets and was able to measure gravity on the spot, we usually have to resort to other methods. The most commonly used technique is to observe ... Read More
