The orbital circumference of a planet is determined by both the mass and size of a planet. Although a planet will orbit the sum in an eliptical sphere shaped orbit, the circumference of these are almost always relative to the mass and density of the planet. It is also determined on how far away it is from the sun. The orbital circumference of a planet is determined by both the mass and size of a planet.

Earth has the highest mean density of any planet in the solar system.

Mercury has the smallest diameter and the largest average density.

The Earth has the greatest density - average density of 5.497 g/cm3

Saturn has the least density. It is .7 on average. The density is less than waters density. So this planet "float" on water its so light.

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.

The Earth has the greatest average density, of all the planets.

The density of water in terrestrial depends on many different factors. The density can only be determined based on the planet's history, they may have "water", but there could be other things inside. Also the gravity of the planet play a role of the density of the water.

The average density is about 5,427 kilograms per cubic meter (Wikipedia). That's very similar to the Earth's density.

It is not a matter of heaviness or lightness, but density, the average density of Saturn is less than the density of water.

The force of gravity is determined by (a) the masses involved, and (b) the distance between the masses. Of course, in the case of a planet for example, you can determine the mass if you know its average density and its size. Note that for a homogeneous sphere, the force of gravity on an object outside the planet is the same as if all mass were concentrated in the center.

Saturn has a very low density overall, on average it is 0.7 g/cm3, less than the density of water. It is the least dense planet in our solar system.

The average density of Jupiter is 1.3 (g/cm3), which is about one fourth as dense as the planet Earth. Jupiter is the largest planet in our solar system and the closest gas giant to the sun.

Mercury comes in 2nd place - average density (5.44 g/cm3 == ==

An average temperature, stable atmosphere, and solid composition.

== == The average density of the planet Earth is 5.52 (Standardized Result 5.52 g/cm3) the density of core of earth is 8 g/cm3

1. The chemical element has a density of 15,534 g/cm3 at 20 0C. 2. The planet Mercury has a density of 5,427 g/cm3.

Uranus has an average density of about 1290 kilograms per cubic meter. In contrast, Earth is much denser at an average 5520 kilograms per cubic meter.

Saturn wins by a considerable margin. It's the only planet less dense than water.

Saturn would float in water if you could find a big enough tub and the water to fill it.
