I have searched on multiple websites for the answers to these questions, but I can't find them. What do scientists say the density of the earth is? How do scientists actually measure the earth's density?
Answer 1:

The radius and the mass of a planet are very important in order to calculate the density of that planet. The mass of the planet can be calculated using spacecraft tracking; then, the ratio of mass to radius cubed is the DENSITY. Density is the most critical variable to know in order to understand the evolution and nature of the planet.


Answer 2:

You can find interesting information for this question on the following link density of the earth, this information is already stored on our database.
