In physics, density is defined as the ratio of the mass of an object to the volume of space the object takes up. Mathematically, this would be written as D = M/V.[1]
Planetary densities[]
Astrophysics concerns the densities of astronomical objects:
| Planet | Average Density (gm/cm3) | Required Mass for 70 cm3 (gm) |
|---|---|---|
