"Plasma Tails" on planets
Is there a way to model the phenomenon of "Plasma Tails" of planets?

It's known that Comets exhibit this feature as it is very much visible, but it's been seen within Venus' dark side and seems to be a feature not unique to these bodies. I'd like to be able to re-create these features within a sort of "vacuum" of Earth, the Moon, and the Sun, wherein the Earth passes through plasma "meshes" or particulates(theoretically bound by their own electromagnetic field or part of a CME) and either absorbs the energy via seismicity, and/or rebounds it in form of geomagnetic fluctuation.

Sometimes, a pseudo-stable mass of plasma forms on the dark side of bodies, but I believe our Moon prevents one such event from ever reaching a pseudo-stable state behind Earth, either due to its own electro-magnetic influence or by sheer tidal effect. It may even enhance the Aurora due to a push-pull on the dark-side plasma.

The primary conditions for these phenomenon include exposure to solar rays and wind, and ionization of plasma and other particulates(either due to a geomagnetic dynamo, or near-imperceptible "plasma vortices" lingering about our solar system which interacts directly with the atmosphere of the body). That, at least, is my understanding of the model which explains these phenomenon.

I believe the ionization takes place intermittently, where the Earth will periodically absorb some of the plasma's energy, convert it to some other function(dynamo), and then release a charge back into the Ionosphere wherein the Aurora will make an appearance. There is no shortage of plasma or particulates in space which get caught in Earth's gravity or electric field, so having the ability to play around with the stuff would be amazing.

On this page, it is described that early Astronomers recognized a visible phenomenon that I believe is closely related to what I have described above: https://en.wikipedia.org/wiki/Lunar_soil#Moon_dust_fountains_and_electrostatic_levitation

This is not to be confused with the Magnetotail of Earth, but rather to be imagined within the Magnetosphere itself as perhaps a very dynamic "body" of charged particles participating in numerous other functions.


Off-topic: If it looks like I have no clue what I'm talking about, I really don't. There are thousands of ways to pick this post apart. As I have written this, I understand the vast undertaking and leaps-to-conclusions which are necessary to put this into Universe Sandbox, so if this is just poppycock then never mind this horrendously uninformed and presumptive post. Eventually, though, I will figure it out, and acknowledge/correct the flaws in my understanding of things.

In this game plasma tails are caused by solar wind blowing away a body's atmosphere, hydrogen, and water. You can get the tail effect by placing an object with one of these properties and no magnetic field close enough to a star.

Well, that's cool for the visuals, at least.

its not just visuals. particles of the object's mass get blown off if conditions are right.

the variables in question are object temperature, mass, and composition. lighter things get blown off with lighter masses and lower temperatures.

I guess you completely brain farted about what a Plasma tail is. I do not have time for non-scientific rabble

you've countered me, but offered no specific criticism of how i am wrong. perhaps you should review how science works.

anyhow, getting very technical about this, you're really asking for the particles i just described to interact with a simulated magnetic field. your original post would be better served requesting the magnetic field in the simulation to be more than a visual.
