There are (5) Lagrangian Points in the Earth & Sun system. Lagrangian Points (also known as Lagrange Points) exist within allocations of space between two bodies of mass and their respective gravitational influence. So, the Earth/Sun system includes the area that the Sun effects with it's gravitational pull on the Earth as well as the Earths area of gravitational effect. Another... If you draw a circle around the Sun including the Earth within it; drew another circle around the Earth as far out as the effect on Mass exists and then converged the two with a third all encompassing circle- that is the system.
The two masses interaction and influence over one another, effect all additional objects that occupy any space within the final circle. As with general relatively and space curvature, all objects orbit if influenced to do so. So, within this system of massive influences on things in orbit; opposing orbits and lines of three interacting orbits exist. When two masses encounter a third as an interference to the balance of the two; both of the massive objects relinquish force, as they are in perfect balance, over the third object. As such, the object is not pulled in an orbit because there is no definitive superior force either way and it will stay 'parked' within this location.
There are (3) unstable locations and (2) stable. The unstable are located at a particular area at which the mass effect of each planetary body is evenly split (ex. between the Earth and Sun) and then an object comes to lie directly between the mass gravitational pull of both on one another. This example is a representation of L1 which lies between the Earth and Sun and is also conveniently the location of a satellite that acts as an observer to our sun.
Another Lagrange Point lies on the opposite side of Earth and allows for a fantastic view of the Universe and is rightly occupied by satellite's and in the near future a telescope. The third unstable Lagrange Point lies behind the Sun and is not in sight of the Earth. As such, it has been victim to many Science Fiction story lines (Planet X) and other such elaborations.
The stable Lagrange Points lie at an angle to the Sun and Earth; the angle is created by taking a line between the Earth and Sun and using that line as the bottom to two right triangles. So, one triangle extends to the right of the line and one to the left. At the top of these triangles (which are essentially pointing to the Right or Left, not up) are the two stable Lagrange Points (easy explanation disclaimer, outward triangle line length determined by mass and distance; not just distance; and is an area, not a point.)
So, to summarize. The 'unstable' ones are titled L1, L2 & L3. L1 is located between the Sun and Earth. L2 is located on the other side of the Earth, also in line with the Earth and Sun. And the third is located on the other side of the Sun, in line as well. L4 and L5 are the 'stable' Lagrange Points and are located to the (R) and (L) of the Earth Sun Line, respectively.
These Lagrange Points exist in all such 'systems' of two masses gravitational pull on one another. There are examples of such points accumulating debris and mass and as such have orbiting masses of their own.. And to maintain an object within the unstable Lagrange Points there is need for adjustments so as to not be tossed out in space at interval based instabilities.
As with all things in space and interaction of mass, I am intrigued. And as such laws predict, the rain falls on my roof today while my neighbor cuts down trees ~ interesting...
03.09 ~ I am but human, in my thoughts and desires- in my inconsistencies. It makes my opposing decisions no less real, no less quantitative... confusion is but the eye of truth, beckoning reason. ~ 03.12 ~ Time. It's existence is action progression, regression, reflection and projection. What in time is solidified and carried to another time is my choice. In one choice you lose all others; as an atom appreciates when the observer decides. It's a blue ocean of intrigue and a wave of contentment- that I am lost in, whilst, carried by. ~ 03.23 ~ That we are all part of one pulsing energy of life.. ~ 3.28 ~ There is no greater power, than the power of words. In speech we pass each other in halls, ride in elevators and embark in the great adventure that are words - with all of their beauty and intrigue. There are no wrong words spoken, only wrong interpretations and implications. Honest words are organic, true and expressions of what we are; existing autonomously and innocently, regardless of what others may think of them. 3.30 ~ That, the more I learn, the more I realize how little I know. It certainly doesn't help being in the company of those who have succeeded in accumulating far more knowledge than I. Is the differentiation between intelligence and knowledge simply the accumulation verses the ability to learn/understand? Or, are the two interchangeable. I feel as though time is passing faster than my ability to accumulate... do other people share this conundrum, I wonder... 4.02 ~ That, "It is what it is" isn't exactly accurate. "It is what I make it" is more so... 4.08 ~ That, "it's not time that matters... it's that mattering is what makes time." 4.12 ~ I watch and wonder... think and ponder... about it. Should I find that I have analyzed to much, to little; or that the quandary was all for not, I'll not know till the applicable time has passed.I hereby instill time as my guide, innocently and fully without disposition and without angst. (4.17) ~ Though random, we should not ignore paths crossed. Just as, we should not entirely exclude emotion from our conclusions. (4.26) ~ That I dispise my lack of control over my own intentions and wonder why I am so weak in this regard. (4.27) ~ That I have opened doors, I wished to open, while simultaniously putting other doors at risk of closing. It's not with resistance I contemplate, it's with anxiety. (4.28) That, I should take a break. Time to simply be, for a bit. (5.01) Its hunger drives decent of rational, a battle of wit and need. Like rain pouring down, wisped by winds, settled by gravity, I’m drawn to it ~ KAS
