Do the terrestrial planets have much smaller masses than the Jovian planets?
The cores of jovian planets are very similar to terrestrial ones. Jovian planets are simply a more evolved form of terrestrial planet contrary to popular perception. Jovian planets often have a lot of hydrogen, helium, methane, and/or volatile ices to make up its atmosphere to the point where oceans of these components cover the terrestrial core and billow the atmosphere to large proportions. Terrestrial planets absorbed less of these components from the leftover solar nebula leaving only the rocky surface and maybe some gas of an atmosphere.
What is the definition of gravitational instability theory?
Is a theory that the jovian planets are formed directly form the instabilities within the gases.
Is Jovian planets located beyond the orbit of mars?
Yes. Jove is the one of the alternate names for the Roman chief god Jupiter, so "jovian" means "Jupiter-like". The four "gas giant" planets, Jupiter, Saturn, Uranus and Neptune, all are further from the Sun than Mars is.
What are located beyond the asteroid belt 3 AU from the sun have extremely large masses and very low density?
Comets are fairly small bodies of rock and ice which are in a highly eccentric orbit around the sun. The actual nucleus of a comet can be between a few hundred metres across, to 40 or more km in diameter. Their mass is quite low, but their density is also quite low as they are mostly made of water ice and frozen gases. They spend most of their time slowly orbiting the sun, far out beyond the outer planets (and way beyond the asteroid belt). Their orbit eventually brings them close to the sun, where the surface is heated and gives the comet its tails.
What is the difference between a satellite and a galaxy?
Satellite galaxies are typically small galaxies orbiting a larger galaxy. In our case, the Large and Small Magellanic Clouds are dwarf galaxies just beyond our Milky Way, but their velocity is high enough they are probably not satellite galaxies. Our sister galaxy, Andromeda, is orbited by about 14 dwarf galaxies.
How do Jovian and terrestrial planets compare?
Jovian planets are gas giants made mostly of hydrogen and helium, while terrestrial planets are rocky planets with solid surfaces. Jovian planets are much larger in size and have thick atmospheres, while terrestrial planets are smaller and have thinner atmospheres. Jovian planets have many moons and ring systems, while terrestrial planets have fewer moons and no rings.
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.
Are the jovian planets similar in mass to the terrestrial planets?
No. The Jovian planets are much more massive than the terrestrial planets.
How does the chemical composition of the terrestrial planet atmospheres differ from the Jovian planets?
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.
What are the two main reason why Jovian planets have much thicker atmoshperes than the Terrestrial planets?
While terrestrial planets are made of rock and have gases in the atmosphere, jovian planets are made almost entirly of gases. If an atmosphere is made of gases in a planet, then the atmosphere of the planets with more gases will be thicker.
Is venus jovian or terrestrial?
Venus is a terrestrial planet, not a jovian planet. Terrestrial planets are rocky and have solid surfaces, while jovian planets are gas giants.
Terrestrial and jovian planets?
Terrestrial planets are rocky, smaller, and closer to the Sun, such as Mercury, Venus, Earth, and Mars. Jovian planets are gas giants, larger, and further from the Sun, such as Jupiter, Saturn, Uranus, and Neptune. Jovian planets have thick atmospheres mainly composed of hydrogen and helium, while terrestrial planets have thin atmospheres and solid surfaces.
What are the two major ways that the terrestrial planets and the jovian planets differ?
Terrestrial planets are small, rocky, and have solid surfaces, while jovian planets are large, gaseous, and lack solid surfaces. Jovian planets also have thick atmospheres composed mostly of hydrogen and helium, while terrestrial planets have thinner atmospheres with varying compositions.
Is Mercury a Terrestrial Planet or a Jovian planet?
The Jovian planets are Jupiter, Saturn, Uranus, and Neptune. They share many characteristics including their location outside of the asteroid belt (between the orbits of Mars and Jupiter).
Is a Jovian planets is call Inner?
Inner planets are terrestrial planets outer are jovian planets
Is the average density of terrestrial planets the same density as Jovian planet?
No. Terrestrial planets are much denser than Jovian planets.
What are terrestrial planets and jovian planets?
Terrestrial planets are rocky, dense planets that are closer to the sun, such as Mercury, Venus, Earth, and Mars. Jovian planets, also known as gas giants, are larger planets made mostly of gases like hydrogen and helium, and include Jupiter, Saturn, Uranus, and Neptune.
