Jovian planets
The 4 Jovian planets are Jupiter, Saturn, Uranus and Neptune. They are all larger than any of the other planets.
The outer planets are Gas Giants, also known as Jovian planets.
Jovian Planets: Gas GiantsThe gas giants, popularly referred to as the Jovian planets, are the planets which are not composed of any solid matter. Technically speaking, the planets which have 10 times more mass than the Earth are classified as the Jovian planets. The examples of Jovian planets in our solar system, include the planet Jupiter, Saturn, Uranus and Neptune. These planets are referred to as the Jovian planets owing to their stark resemblance to the planet Jupiter, the largest planet in the solar system. Other than these four planets in our solar system, several other gas giants have been discovered in outer space.Terrestrial Planets: Inner PlanetsTerrestrial planets, also known as the rocky planets or the telluric planets, are those planets which are predominantly composed of silicate rocks. The examples of terrestrial planets in the solar system are Mercury, Venus, Earth and Mars. These planets resemble the planet Earth to a significant extent, and hence they are referred to as 'Earth-like' or 'terrestrial' (derived from the Latin word the Earth - terra). Other than the Earth, and three other terrestrial planets in our solar system, the scientists have identified a number of planets with terrestrial traits in outer space.Jovian Planets Vs Terrestrial PlanetsThat brings us back to the terrestrial planets vs Jovian planets comparison. The most basic difference between Jovian and terrestrial planets is their size. While the Jovian planets are gigantic, the terrestrial planets are considerably small. In fact, the smallest Jovian planet is 10 times larger than the planet Earth, which is the largest terrestrial planet. Even in terms of the mass, Jovian planets score over their terrestrial counterparts. The smallest Jovian planet has 15 times more mass than the Earth. The surface of the Jovian planets is made up of gases, while the surface of the terrestrial planets is made up of solid rock. Similarly, the atmosphere of the terrestrial planets is predominantly made up of nitrogen and carbon dioxide, while the atmosphere of the Jovian planets is made up of hydrogen and helium. As far as the distance from the Sun is concerned, the terrestrial planets are closer to the Sun, and hence are referred to as inner planets, while the Jovian planets are farther, and hence are referred to as the outer planets. Surprisingly, however, the speed at which the Jovian planets rotate is much faster than the terrestrial planets. The density of the terrestrial planets is five times that of water, while the density of the Jovian planets is as much as that of water. Yet another point of difference between the Jovian planets and the terrestrial planets is the number of natural satellites. While the terrestrial planets either have none or a very few (Mercury-0, Venus-0, Earth-1 and Mars-2), the Jovian planets have a large number of them.
Yes, all four Jovian planets (Jupiter, Saturn, Uranus, Neptune) have rings. However, Saturn's rings are the most prominent and well-known due to their size and visibility from Earth. The rings of the other Jovian planets are much fainter and less substantial.
Yes, Jovian planets are thought to contain much less rocky material compared to terrestrial planets. Jovian planets are primarily composed of gases like hydrogen and helium, with a small rocky core at their centers. Terrestrial planets, on the other hand, are predominantly made of silicate rocks and metals.
Uranus has the largest axial tilt among the jovian planets, with an inclination of about 98 degrees. This extreme tilt causes Uranus to essentially rotate on its side compared to the other planets.
The four Jovian planets in our solar system are Jupiter, Saturn, Uranus and Neptune. The four terrestrial planets are Earth, Venus, Mars and Mercury. The difference between the Jovian planets and the terrestrial planets is that Jovian planets are enormous and made of gasses and ices while terrestrial planets are relatively small and made of rocks and metals. Other differences are that terrestrial planets have high densities, rotate slowly, have no moons or magnetic fields and have thin atmospheres (Earth is an exception because it has a moon and a magnetic field), while Jovian planets have low densities, rotate rapidly, have many moons and a magnetic field and have thick atmospheres.
The Jovian Planets are Jupiter, Saturn, Uranus, and Neptune. The word "Jovian" means: "things that are similar to Jove". Jove, in Roman mythology, was another name for Jupiter, the chief god.The Outer/Jovian planets are as follows:JupiterSaturnUranusNeptunePluto is not included anymore. (and never was; too small and dense)
Terrestrial planet atmospheres are primarily composed of gases like nitrogen and oxygen, with small amounts of carbon dioxide and other trace gases, while Jovian planet atmospheres consist mostly of hydrogen and helium, along with traces of methane and ammonia. Terrestrial planets have thinner atmospheres compared to Jovian planets, which have massive, thick atmospheres made up of mostly hydrogen and helium.
Yes, Jovian planets like Jupiter and Saturn are predominantly made up of hydrogen and helium. These gases make up the majority of their composition, with smaller amounts of other elements and compounds present as well.
The jovian planets have no solid ground just compressed gases the terrestrial planets have solid ground. The Jovian planets are named gas giants because they are farther then the sun and are not solid and the terrestrial planets are closer to the sun and do not have as much gases.
