As we might all know, planetary data like masses, sizes, and interplanetary distances are now readily available and well- arranged in books and across the internet. Self-evidently, it is impossible to measure those data directly. Isn’t it curious at how those values were acquired? Let’s take a look at one of the early triumphs of physics as the primary tool for such field of intellectual quest – the determination of the mass of the Earth.
