Again with these threads! (no disrespect, Cappy) 
I'm just saying that because I see this topic a lot. I know it's very important, but it's mostly speculation and we will most likely not arrive at a conclusion which best suits everyone.
This was also my first topic when I joined LL, lol.*Taurus - Venus & Earth
Since the Earth is opposite of your Sun sign, then your Sun sign is looking toward your Earth sign, and I have a theory that it's looking toward it to find security and stability (Taurus) to complement it's willpower and consciousness. (Sun)
Also, since Earth is opposite the Sun, it can mean your Earth is the building of your self; stabilization... meaning your Sun is your self, and you start to look toward your Earth for the guidance and transformation of your self. They are opposite from each other, so it's also like how opposite signs look towards each other.
Just like how the self needs to feel worthy, they look toward the Earth; which rules Taurus. So maybe that can give a reason why it can be associated with the 2nd House of self-worth. Because we try to become that, we try to become worthy in our own sense of self. The self gets inflated, (Sun) so it needs the Earth to ground it and show how much it's really worth.
Another way you can look at it is we're trying to build upon (the Sun) a better foundation (looks to Earth) to live on the Earth with other people.
(if the Earth can indeed have an astrological influence on us, which is why this theory can kinda complement that because if only planets around us have an astrological influence, (Geocentric) then this helps bridge the gap because it isn't technically giving us the influence from afar, but rather the Sun and Earth are complementing each other, which is why they are the exact same degrees, but just opposite from each other. So one can automatically know their Earth sign from their Sun sign and do not need to look at a calculated chart or ephemeris, unlike other planets)
For example, I have a Virgo Sun and Pisces Earth, so I'm looking toward my Earth to learn to be more imaginative and intuitive rather than being so calculating and logical. I'm trying to ground myself with a higher understanding of spirituality, imagination, creativity and intuition so that I can thrive on the right hemisphere of the brain (Pisces/Neptune/Jupiter) as I do with the left hemisphere of the brain. (Virgo/Mercury/Vulcan)
Just like the Virgo/Pisces axis. Or however you personally interpret the Virgo/Pisces axis, (or any sign axis you're using for the Sun/Earth opposition) then that is how ones Sun and Earth work.
I mean, if the Sun can rule over a sign, why couldn't the Earth as well, right?
Taurus is also the most earthiest of the earth signs, so it also seems fitting.

*Virgo - Mercury & Vulcan (if it exists) or Chiron or Pallas
Mercury being Virgo's co-ruler while (insert ruler(s)) are it's main rulers.
-If I'm allowed to select two rulers, including Mercury, and excluding Vulcan from the equation, then Chiron and Pallas.
-If I'm allowed to select two rulers, including Mercury, and including Vulcan into the equation, then Vulcan and Chiron.
-If I'm only allowed to select one other ruler besides Mercury and excluding Vulcan, then Chiron.
Pallas is pretty close in the decision against Chiron, though.
Either way, Mercury is Virgo's co-ruler for every option in my decisions, just as Jupiter is Pisces's and Saturn is Aquarius's, etc.
(that whole thing probably confused the hell out of people, lol)
My original theory I had before I found out about Vulcan for Virgos ruler that I hypothesized was that Ceres, Chiron, Pallas and Vesta used to be apart of one bigger body that was Virgo's ruler. And that it was struck by a large asteroid or something and blasted into pieces. But that couldn't make much sense because they aren't near each other, but that doesn't mean it isn't possible. Perhaps they were knocked far away from each other and spread throughout the Solar System?
But I believe now that Vulcan is Virgo's ruler.
My theory on Vulcan is not what ever the Mythology says it's supposed to be.
If Vulcan is this raging, disruptive and thundering being, then that is most certainly not Virgo.
In Mythology, Vulcan was a skilled blacksmith/craftsman and the god of fire and volcanoes. And it's Greek Mythological counterpart is Hephaestus. He created tools for the other Gods.
(I also might be getting Vulcan and Vulkanus's mythologies confused, with Vulkanus being the raging, thundering being)
Since this is not directly linked with Vulcan's Mythology, my theory apparently cannot be true. If Vulcan has to relate to Vulcan's Mythology, then I have no idea why some astrologers believed that Vulcan rules Virgo, as the Mythology of Vulcan seems hardly like Virgo, besides being a skilled craftsman for the other gods. (Which Virgos like to serve people, such as their bosses or people in authority. As bosses/superiors or people in authority have the attention on them, while Virgo has little to no attention on him/her).
I mean, obviously there are multiple Virgo archetypes, so it's not like all of them are Virgo, that cannot make sense when you have multiple Virgo archetypes from the same Mythology and culture. (Roman, Greek, Egyptian, etc)
So what I'm trying to say is, Astrology gave ideas to Mythology, and we're still learning about Astrology and Astronomy, so how can I be wrong?
(I'm obviously not well versed and informed with Mythology, but I am just trying to make the best of my knowledge of Astrology)
The festival of Vulcanalia is celebrated on August 23rd each year, which is the time of the year when the heat from summer causes crops to be burned more easily. Interestingly though, it's the day the Sun enters the sign of Virgo. Vulcanalia is a festival which celebrates the god, Vulcan.
Anyway, well first, what is Vulcan? It is the hypothesized Intra-Mercurial planet between the Sun and Mercury. It cannot be more than about 8.30 degrees away from the Sun.
Why we cannot see it in my opinion: It's in between the Sun and Mercury. But I read it's really small and some people have saw it by accident, (I don't remember the details) but it's too dangerous to the eye if someone were to look into a telescope because the reflection of light from the Sun will damage your eyes severely. It can also be hard to see because of the light from the Sun reflecting making it a shadow planet, therefore not easily visible, if visible at all. (I'm not an Astronomer/Astrophysicist, so please forgive me if that doesn't makes sense, haha. I'm 90% sure that Vulcan doesn't exist anyway, but like I've been saying... it's just a thought).
What I believe Vulcan represents is your sense of logic, analysis, critical, discerning and detailed mind, and cognition. While I believe Mercury is your communication, information (data), thoughts, ideas, and reasoning.
I believe both of them work systematically to make up your intellect, (Let's dub it the "Duo of Intellectualism") while the Sun, Mercury and Vulcan make up your consciousness. (Let's dub it the "Triad of Consciousness") ~ (with Chiron governing our overall sense and level of consciousness; how we interpret, reflect and utilize it). It's very close to the Sun. So while Mercury controls our communication and ideas, Vulcan controls our logical and critical thinking, which lays out the foundation as to how our communication and thoughts (Mercury) are formulated, organized and implemented (Vulcan). The Sun, Mercury and Vulcan all work together systematically in a way, since both Mercury and Vulcan are close to the Sun, so they play a crucial role in the personality's (Sun) manifestation to make up your consciousness (Chiron).
Just how Mercury can only be in the same sign or signs next to the Sun sign, Vulcan does the same, except it has a much higher chance to be in the same sign as the Sun sign because it can only be about 8.5 degrees away from the Sun. So this is why the Sun signs usually have their own way of logically understanding something, because (for Ex) most Virgos will have their Vulcan in Virgo, so they are rather calculating and have good common sense for the most part, regardless of their Mercury. Unless they have their Vulcan in a different sign, like Libra, then this can make them more ideal and maybe air-headed and less specific, cold and factual with their critiquing and reasoning than a Virgo Sun with Vulcan in Virgo.
So for Ex. a Virgo Sun with a Leo Vulcan and Libra Mercury will communicate with a broad vocabulary and ideas, but those words or ideas may not be as organized and perhaps more hasty, but with a more creative structure and vibe.
And for Vulcan to fit into the 6th House? Well, let's just say that it owns the 6th House as well, along with Mercury. It's a daily thing to apply logic (Vulcan) and thoughts (Mercury) in your everyday life. Vulcan serves (6th House) your life-force expression of consciousness (Sun) and well being (health) by helping to understand and conquer your mind's own psychological problems by being rational. A rational, put together mind is a healthy mind. And a healthy mind manifests itself into a healthy body because most of the time, it's a matter of state of mind which determines your health. 
I would say that Vulcan must be within a 2 - 3 degree orb with the Sun in order for it to be considered a conjunction. Within a 1 degree orb for a tight conjunction, and 0 degree orb for an exact conjunction.
The reason why Vulcan; the hypothetical, Intra-Mercurial planet supposedly rules the sign; Virgo, is because it's pretty much astrological deduction, meaning it has to. This is because if a planet "does exist" between Mercury and the Sun, it must rule Virgo because Virgo's characteristics and mental facilities (previously governed by Mercury) are the uttermost importance, as they're the base intelligence for someone; their logical intelligence/common sense. And the inner/personal planets are very important in constructing the psyche's facilities (Mercury, Venus, Mars... and possibly, Vulcan). Therefore, if a planet should only rule one sign (as Modern Astrology dictates Uranus ruling Aquarius, Neptune ruling Pisces and Pluto ruling Scorpio) ~ (and Astrology "should" be modernized, just as Science it because of new information and knowledge), then it will only make sense that the unknown planet that rules Virgo would be Vulcan, as it is both the "most" important mental facility (Mercury and Vulcan), as well as psyche's facility (Mercury, Venus, Mars and Vulcan). Which is why Vulcan takes away the more important characteristics of Mercury (it's logical/analytical characteristics) because it's closer to the Sun, therefore, more personal to the psyche. Because understanding something (Vulcan) is more important than communicating and drawing reason (Mercury) because it is the first step in developing an advanced mind. If you can't understand something, how will you draw reasoning and communicate it? You can't.
Vulcan domicile - Vulcan in Virgo is very analytical and detailed-oriented. They spot tiny flaws others would miss. Not because others overlook them, but because this is simply how their mind works - to look for the logic missing within it and criticize (your mind automatically does it, but does not communicate it's flaws - which is Virgo Mercury) it's validity within your own understanding of how the Universe's logic works. Every thought must be categorized and arranged, with perfection of execution. Their thought process works methodically and good at looking at something with a sequence of logical events. Their communication would have perfect composition and structure. Whereas a Virgo Mercury would have perfect grammar, punctuation, capitalization, etc.
It's similar to Mercury in Virgo, except it's not about the way you communicate or thought patterns, such as a practical outlook and ideas, but rather sense of logic and understanding. A Virgo Mercury would usually be quiet, criticize everything, either elaborate something with a lot of details, or make is concise and break it down for someone to understand.
So to summarize the difference between Vulcan and Mercury ~ Vulcan is one of the planets which governs our base intelligence; our sense of logic, analytical, critical, discerning and detailed mind, and cognition. Mercury is the other planet that governs our base intelligence; our intellect, how we communicate our thoughts and ideas, and reasoning (how we form our understanding and cognition (Vulcan) into a proper and established thought process (Mercury) and then communicate it; reasoning (Mercury). Without these two planets (which are very dependent on each other; so once their energies bind together, they form our intellect), you cannot proceed to any form of higher learning or understanding of anything, period.
One interesting thing Starlight said is that since Vulcan orbits the Sun it sounds like a Virgo thing. Virgos are supposed to orbit their bosses, work stations, places of employment, or jobs so this is reminiscent of Vulcan orbiting the Sun. 
(now remember, this is all my opinion and theory)
All of the rulerships in my opinion:
Sun - Leo
Moon - Cancer
Mercury - Gemini & Virgo
Vulcan - Virgo
Venus - Libra & Taurus
Earth - Taurus
Mars - Aries & Scorpio
Jupiter - Sagittarius & Pisces
Saturn - Capricorn & Aquarius
Uranus - Aquarius
Neptune - Pisces
Pluto - Scorpio
Of course I'm not expecting anyone to believe Vulcan ruling Virgo, let alone even existing, lol. But it's an idea, that's all 
Either each sign has ONE ruling planet and ONE co-ruling planet, (maybe 2 co-rulers at minimum, but having one modern ruler and one co-ruler seems better than two co-rulers) or just the traditional rulers. No sign should have like 6 like Virgo is suspicious of having an affinity with, lol. (E.g. - Chiron, Vulcan, Ceres, Vesta, Pallas and Mercury)
