Astronomical observation can tell us two fundamental aspects of a planet -- its diameter and the extent to which it disturbs the orbits of other nearby planets or moons.
That extent of disturbance of its neighbors indirectly tells us the mass of the planet (the disturbance will be proportionally larger with a larger mass).
Given the diameter, we can infer the volume. Divide the volume by the mass and we realize the density of a given planet.
Mercury has the second lowest density of any planet in the solar system. Saturn has the lowest density of any other planet.
Density of a planet = (Planet's mass) divided by (Planet's volume)
Density is calculated by dividing the mass and volume of an object.
Certainly - all matter has density. The density of a gas planet would probably be less than that of a more solid planet but it would still have a non-zero density.
Earth's density: 5520 kg/m3 Saturn's density: 690 kg/m³
The planet with the lowest overall density is Saturn.
The density of a substance is determined by its mass and volume. It is calculated by dividing the mass of the substance by its volume. The formula for density is: Density Mass / Volume.
density is how dense an object is (see dense) it is calculated by dividing the mass by volume of an object. density can be changed by changing the size or shape or the object
No, it is mass divided by volume: like grams per cubic centimeter, for example.
size, mass, density, and volume. Other than that, its VERY different
This planet could be Saturn, as its average density is around 0.69 g/cm³, which is lower than the density of water (1.0 g/cm³).
The density of a planet depends basically on the density of the materials that make the planet up. It is a weighted average of those densities.
