Difference Between Terrestrial Planets and Jovian Planets

Main Difference

The main difference between Terrestrial Planets and Jovian Planets is that Terrestrial Planets are stuffed with dense or tough surfaces, whereas Jovian Planets are classified by gaseous or airy surfaces.

Terrestrial Planets vs. Jovian Planets

Terrestrial planets are filled with solid or robust surfaces or land. But on the other hand, jovian planets are distinguished by gaseous or aerial surfaces. Terrestrial planets have a sturdy, metallurgical pith ( just like to that of Earth’s) that is bounded by silicate substances. On the other side, jovian planets are enormous and massive planets with cores or pits of lower consistency.

The atmosphere of terrestrial planets is composed of carbon dioxide and nitrogen, which are root in plenty or abundance in terrestrial planets. On the contrary, the atmosphere of jovian planets is made up of helium, methane, hydrogen, and ammonia; it is supposed that these planets have a pith composed of magmatic rock. The terrestrial planets in our planetary system are Earth, Venus, Mercury, and Mars; on the other hand, the jovian planets are Neptune, Saturn, Uranus, and Jupiter.


The terrestrial planets are nearer to the Sun, whereas the jovian planets are distant from the Sun. The terrestrial planets rotate in a smaller amount; on the other side, the jovian planets rotate or spin more, and owing to this reality. The terrestrial planets suppose to be less compressed at the poles and have weak gravitational force; on the other side, jovian planets have a strong magnetic force.

Terrestrial planets are wrapped with solid, tough, or rocky surfaces.Jovian planets are consists of aerial or vacant surfaces.
Terrestrial planets are small in size (around the mass of Earth).Jovian planets are large (around ten times the volume or mass of the Earth).
The surface of terrestrial planets is rocky, typically with big iron piths.Jovian planet has no solid surface, but these are gas giants.
Its atmosphere is composed of carbon dioxide and nitrogen.It is composed of Helium and Hydrogen with traces or clouds of Water, Methane, Ammonia, and other complicated molecules.
It has three ancillaries or satellites, one for Earth and two for mars in total.It consists of more than one hundred satellites; most are formed mainly of ice. A few of these satellites or ancillaries are of the planetary size and still have climate and atmosphere.
Terrestrial planets in our planetary system are Mercury, Venus, Earth, and Mars.The jovian planets of the planetary system are Saturn, Neptun, and Uranus.

What are the Terrestrial planets?

Terrestrial planets are also termed as terrene, rocky, or substantially planets are composed mainly of iron or silicate rocks, which consist mostly of Earth’s outer layer, rocky moons, and asteroids. Our planetary system is consists of four terrestrial planets: Mercury, Earth, Venus, and Mars. These are the inner planets nearby to the Sun. The terms terrestrial planet and telluric or terrene planet arrive from the Latin terminology Tellus and Terra, both of which means Earth.

Terrestrial planets are generally specified by an inner hardcore coated with a silicate covering. Earth’s single satellite, the Moon, has an analogous but smaller iron center. Lo and Europa, two moons of Jupiter’s numerous moons, are composed of an inner structure analogous to terrestrial planets. Relying on tectonic or morphological activities and the occurrence of mountains, water, volcanoes, tumblers, craters, and further land patterns can colonize the exterior of terrestrial planets. Additionally, terrestrial planets have a subsidiary climate, which is intensified by comet effects and volcanic or impulsive activity.


Few solar masses external to our planetary system, called an extrasolar planet, have been set up to be terrestrial, and the first-ever more well-known terrestrial exoplanet is Kepler-10b, exposed by the Kepler task in 2011. In a similar year, Kepler astrologer published a list of above 20 exoplanets that are likely to be terrestrial.

What are the Jovian Planets?

Jovian planets are gigantic planets typically with a principal composition of gases or ice as a substitute for solid material such as rocks. There are a total of four jovian planets in the planetary system, and these are Uranus, Neptune, Jupiter, and Saturn. Presently, there are several extrasolar planets revealed to be revolving around other stars that might be composed of ice or gas.

Jovian planets are occasionally named as gaseous giants, however many astrologers preserve the word to Saturn, and Jupiter extricating Uranus and Neptune as ice giants. Although, both words can be confusing since all jovian planets are made up of liquids beyond their decisive phases. This is when discrete gas and fluid form no longer exists. Saturn and Jupiter highly consist of hydrogen and helium; on the other hand, ammonia and methane mainly made up Neptune and Uranus. Jovian planets are supposed to have a dense and consistent molten or magmatic core of rock substances.

Key Differences

  1. Terrestrial planets have concrete surfaces, low speed, less intense iron cores; on the other hand, jovian planets are made up of non-solid surfaces, quick and faster rotation, much intensive hydrogen, and iron cores.
  2. Terrestrial planets are composed of hard and tough surfaces, while the jovian planets are made up of gaseous and void surfaces.
  3. Terrestrial planets are smaller, while jovian planets are larger.
  4. The climate of terrestrial planets has consisted chiefly of nitrogen gases, and carbon dioxide; conversely, helium gases and hydrogen are found in plenty in the atmosphere and climate of jovian planets.
  5. The jovian planets have extra moons and more moons than the terrestrial planets. Besides, the jovian planets have the capacity to have trinkets or rings about them, which do not appear in terrestrial planets.
  6. Terrestrial planets have closely spaced orbits; on the contrary, jovian planets have widely spaced orbits.
  7. Terrestrial planets have small radii, while jovian planets have large radii.
  8. Terrestrial planets are without rings. But on the other side, jovian planets have many rings.
  9. Terrestrial planets have a weak magnetic field or the force of gravity, but on the other hand, jovian planets have a strong magnetic field.
  10. Terrestrial planets are less massive, while jovian planets are more dense and massive gigantic.


From the above discussion, it is concluded that terrestrial planets are made of solid, sturdy, and concrete surfaces, having low speed and less consistent iron core while jovian planets are made of gaseous or airy surfaces.
