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.
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.
How does the chemical composition of the terrestrial planet atmospheres differ from the Jovian planets?
Jovian planets are less dense when they Are compared to terrestrial planets because they are Mostly composed of hydrogen gas.
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 diameter of the terrestrial and jovian planets compare?
The diameter of a terrestrial and jovian planets are comparable in the sense that the objects orbiting on a terrestrial level are often much bigger than those of jovian planets.
What are terrestrial planets and jovian planets?
The Terrestrial planets are Mercury, Venus, Earth, and Mars. The Jovian planets are Jupiter, Saturn, Uranus, and Neptune.
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.
Terrestrial and jovian planets?
Terrestrial planets are the solid planets like Earth and Mars. Jovian planets are those gas planets like Jupiter and Saturn.
Why are the Jovian planets so much larger than the terrestrial planets?
No, they are less dense as the majority of their volume is composed of very light hydrogen gas. A jovian planet may have a core that is denser than that of a terrestrial planet but, as this is dense, it is not all that large. The hydrogen atmosphere is very large and therefore anti-dense (if you know what I mean). The lightness therefore dominates.
Compare and contrast terrestrial and Jovian planets?
The main difference is size. Jovian planets are very large and terrestrial planets aren't. Jovian planets are also made of gas and terrestrials are made of rocks.
Why are the components of jovian atmosphere so different from those of terrestrial planets?
Because Jupiter is mainly hydrogen.
The most obvious difference between the terrestrial and the jovian planets is?
The size. The gaseous Jovian planets are far larger than the inner terrestrial planets.
