Bigger planets are more likely to be gas giants while smaller ones are more likely to be terrestrial.

This of course is not the answer to your question which is, of all planets that may exist, is there a greater likelyhood of there being terrestrial planets or gas giants?

All of our Solar Systems gas giants have more moons than the terrestrial planets. Jupiter (63), Saturn (62), Uranus (27) and Neptune (13).

They are larger and so they have more gravity.

Unlike terrestrial planets, Gas giants tend to be made up of mostly gas as opposed to rockTerrestrial planets are generally relatively small while gas giants are instead very large. (Historical researcher, D. Vogt stated that the lightest gas giant in the solar system is fourteen times the mass of the heaviest terrestrial planet, Earth.)Terrestrial planets orbit closer to the sun, therefore making them more likely to have extraterrestrial life. Terrestrial planets receive an appropriate amount of heat from their star to support life, whereas Gas giants lack things necessary to support life.In our solar system the four inner planets (Mercury, Venus, Earth, and Mars) are terrestrial planets. Our four outermost official planets - Jupiter, Saturn, Uranus, Neptune - are Gas giants (or Jovian planets).

Terrestrial means on Earth so Earth is the only terrestrial planet This is incorrect, the first 4 planets are terrestrial as they are solidly bound planets. Pluto was also a terrestrial dwarf planet. Any planet can have moons but due to the gas giants having larger gravitational forces they have traditionally gathered more moons. Thusly, no.

Terrestrial planets contain much more of the heavy elements (such as iron and silicon) and less of the lighter elements (such as hydrogen and helium). Terrestrial planets are smaller and denser, and are also closer to the sun, and hence warmer as well. Gas giants are distant and cold.

No, there is more hydrogen on the Jovian planets then the terrestrial ones.

Gas giants have a higher mass. This means that the gas giants have a more gravity to hold moons in orbit around them.

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

That is a little hard to anwer. Terrestrial planets are by far more dense than the outer parts of the gas giants (Jovian planets) BUT . . . far, far, far down inside the Jovian planets is found a tremendous pressure which squeezes the matter there into a very dense state - more dense than Earth.

It's because the gass giants in our soler system are bigger than that of the terrestrial planets so their gravity is stronger, any space rock big enough will get sucked into the planets gravitational field.

All of the jovian planets are more massive than any of the terrestrial planets.

Jupiter (63), Saturn(62) , Uranus(27) and Neptune(13).

The terrestrial planets in our solar system are Mercury, Venus, Earth, and Mars. There are many more terrestrial planets orbiting stars other than the sun.

There are two main types of planets because the two categories separate the planets into more specific groups. 1. Terrestrial planets have a rocky surface and are inside of the asteroid belt that separates the Terrestrial planets from the Gas Giants The Terrestrial planets are: (in order of distance to the sun (close to far) Mercury, Venus, Earth, and Mars. 2. Gas Giants are mostly made up of gasses and are very large in size Gas Giants are: (in order of distance to the sun (close to far) Jupiter, Saturn, Uranus, and Neptune.

Gas giants are much bigger, are more distant from the sun, and are composed mostly of gas (particularly methane and ammonia) whereas the terrestrial planets are composed mostly of rock and metal, are closer to the sun, and are smaller.

Gas giants are larger and there for have a stronger gravitational pull. When the solar system was forming, the larger planets with greater gravitational pulls collected more satellites and therefore have more moons.

Oh no, it is the outer planets which have the most moons. Terrestrial planets such as Earth have relatively few moons.

hydrogen methane silicate minteral or ammonia iceSilicate Minerals are more abundant on terrestrial planets than on Jovian planets.

Yes Jovian planets rotate faster than terrestrial planets. This is because they have more mass relative to their radius and have a more angular momentum.

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

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

The gassy planets are much more massive than the inner planets, which means that have stronger more far-reaching gravitational fields. That in turn makes them more likely to capture odd collections of rock in the solar system.
