Distribution of planets material

In summary, most planets that are close to the sun are usually really hot and rocky, and tend to have very tiny atmosphere, if at all. Going past the rocky planets you tend to see gas giants.

Can we know something of the distribution of planets material in general?

I mean, the percentage of solid, fluid, gas planets in general (maybe theoretically) in solar systems. And percentage of planets with atmospheres?

Well, we know that most planets that are the close to the sun are usually really hot and rocky, and tend to have very tiny atmosphere, if at all. Going past the rocky planets you tend to see gas giants. I haven't heard of there being a natural distribution. It all depends on the mass and temperature of the host sun.

Are there any theoretical calculation?
I mean, for not our sun, but in general?

"most planets that are close to the sun are usually really hot and rocky"

Unfortunately, the crop of 'hot jupiters' has put paid to such simplicity...
;-((
You should check the star's metallicity as this provides a clue to possible construction materials...

Just goes to show that there's no natural distribution.

We are learning more as we get more data.

The problem is that the data is just coming in, and since it's early data it's not clear how much is observational and how much is real. For example, we are seeing a lot of Jupiter-sized planets near stars, but how much of that it because those types of planets are easier to detect is unclear right now.

Stay tuned.

Unsurprisingly, big planets comprise the majority of extrasolar bodies discovered thus far. Kepler is better suited to find smaller, rocky planets.

I would also suspect that presence of hot jupiters could depend on Metallicity of the stars... Is there a correlation? you won't find any rocky planets around type III stars, but there still are hot jupiters around high-metallicity stars...

There is a strong correlation between metallicity and the size of planets and the presence of a Hot Jupiter. Just why is under investigation as both the formation models invoked can make such planets, with similar metallicity correlations, from what I have read.

Very useful link, thank you !
 

FAQ: Distribution of planets material

How is the material of planets distributed in the solar system?

The material of planets in the solar system is distributed in a pattern known as the Titius-Bode law. This law predicts the spacing of planets in a geometric sequence based on their distance from the sun. However, this law has been found to be inaccurate in some cases and the exact distribution of material is still being studied and researched.

What factors contribute to the distribution of planets material?

The distribution of planets material is influenced by several factors such as the initial conditions of the solar system, the gravitational pull of the sun, and the interactions between planets. The composition and density of each planet also play a role in determining how the material is distributed.

Is the distribution of planets material the same in all solar systems?

No, the distribution of planets material can vary in different solar systems. This is because each solar system forms under unique conditions and can have different initial conditions and interactions between planets. However, there may be some similarities in the distribution of material between certain solar systems.

How does the distribution of planets material affect the formation and evolution of a solar system?

The distribution of planets material plays a crucial role in the formation and evolution of a solar system. It determines the size, composition, and positioning of planets, which in turn affects their gravitational interactions and orbits. This can also impact the formation of other celestial bodies such as moons and asteroids.

Can the distribution of planets material change over time?

Yes, the distribution of planets material can change over time. This can happen due to various factors such as collisions between planets, gravitational interactions, and external influences such as passing stars. These changes can have a significant impact on the overall structure and dynamics of a solar system.
