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.

How do Jovian and terrestrial planets compare?

Jovian planets are more massive and lower in average density. Terrestrial planets are smaller and higher in average density.


Is the average density of terrestrial planets the same density as Jovian planet?

No. Terrestrial planets are much denser than Jovian planets.


Are the jovian planets similar in mass to the terrestrial planets?

No. The Jovian planets are much more massive than the terrestrial planets.


Anong the eight planets which have the largest size and least density?

The four Jovian planets


Are the planets that have a higher density the Terrestrial planets or the Jovian planets?

The Terrestrial planets have a higher density. Their structure includes a large percentage of rock, while the Jovian planets are composed mostly of gas.


What planets have more moons on average?

Jovian planets


Why are some planets called jovian planets?

Jovian means Jupiter-like - these planets are made of gas and are several times more massive than the Earth - like Jupiter.


Why are the densities of the terrestrial and jovian planets so different?

The terrestrial planets are primarily composed of rock and the jovian planets are mostly gas (primarily Hydrogen). Rock has a higher density than Hydrogen, giving the terrestrial planets a higher density.


What criteria are the planets placed into either the Jovian or terrestrial groups?

Size, density, composition, and the rate of the rotation are used to place the planets in either Jovian or Terrestrial.


Do the Jovian planets have lower average densities than the terrestrial planets?

Yes


What is the most obvious difference between the terrestrial and the Jovian planets?

The greatest difference is in their size. Gas giants are large but have a very low average density (much of their size includes their atmospheres). From a physical standpoint, terrestrial (rocky) planets have a solid exterior surface. Jovian (gas giant) planets instead exhibit a smooth range of increasing density, and do not have the abrupt change to solidity that terrestrial planets exhibit.


The Jovian planets are more massive but less dense than the terrestrial planets?

Yes, the large and more massive outer planets are made mainly from Hydrogen and Helium. They are less dense than the smaller terrestrial planets.
