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.
What else can I help you with?
Which planet has the lowest density besides saturn?
Mercury has the second lowest density of any planet in the solar system. Saturn has the lowest density of any other planet.
What is the formula for density of a planet?
Density of a planet = (Planet's mass) divided by (Planet's volume)
What is density calculated by?
Density is calculated by dividing the mass and volume of an object.
Does a gas planet have density?
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.
What is the density of the planet Saturn compared to the planet Earth?
Earth's density: 5520 kg/m3 Saturn's density: 690 kg/m³
What planet has low density because it contains of iron and helium?
The planet with the lowest overall density is Saturn.
What determines the density of a substance and how is it calculated?
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.
What is Density how is Calculated How does density change?
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
Is density is calculated by dividing an object's volume by its mass?
No, it is mass divided by volume: like grams per cubic centimeter, for example.
The planet Venus is similar to Earth in its?
size, mass, density, and volume. Other than that, its VERY different
The density of a planet is 0.69 gcm density of water is 1.0 g cm what planet might this be?
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).
How can the density of our planets be explained with mathematical formulae?
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.
