Volume increases with the Cube of the radius, so an easy way to compute the volume of the giant planet is to simply take the ratio of the radius Giant Planet: Earth and raise it to the 3rd power.

Since these planets are the same shape (Spherical) this ratio is accurate enough for our purposes. In the case of an object that is oblate (like Saturn or Jupiter), one can still calculate the volume accurately by taking the Equatorial Radius squared and multiplying it by the Polar Radius.

In this given case the volume of Giant Planet = 14 x 14 x 14, or 2,744x that of Earth.

Since Mass = 681x that of Earth, Density = 681/2744 = 0.248 of Earth's (just a little under one quarter).

You could go one step further to calculate the density of this object by multiplying the density ratio by Earth's density (5.515x water) - so Giant Planet's density = 1.369 grams/cm3.

The average density of the massive Jovian planets is?

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.


Which planet has the lowest average density?

Saturn:)Saturn is the least dense of the gas giants, even out of all of the planets in our solar system. Its average density is around 0.7 g/cc (less than water)


Which planets are lighter than earth?

The planets that have less mass than Earth are Mercury, Mars and Venus. The planets that have a lower average density than Earth are all of them; Earth is the most dense planet in our solar system.


What is the size of planet Jupiter?

Jupiter is a gas giant and the largest planet in our solar system. It has an equatorial diameter of 142,800 km (Earth is 12,756 km). Its mass is equivalent to 317 Earths, and its volume equal to 1321 Earths. It has more mass than all of the other solar planets combined. Mass = 1.8986×1027 kg Volume = 1.43128×1015 km³ Radius = 71,492 km's (Earths radius is 6,378 km's) Mass = 317.83 Earths Average density = 1.3g/cm3


Compared to the density of liquid water 1 gram. what is the average range of density in the terrestrial 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.
