<s>[INST] How heavy is the earth? [/INST] Earth has a mass of about 5.9722×10^24 kg.</s>\ <s>[INST] Cool. How can the earth's mass be measured? [/INST] Interesting question! Calculating Earth's mass is possible by using factors such as density and gravity. Earth's mass was calculated quite accurately in the 1789 Cavendish experiment with a derivation of around 1 percent.</s>\ <s>[INST] Go a bit more into detail for me. What roles play the different factors in the calculation? And how were they used in the cavendish experiment? [/INST]
