Oort Cloud
Information from NASA:
The Oort Cloud is believed to be a giant spherical shell surrounding the rest of the solar system. This is unlike the orbits of the planets and the Kuiper Belt, which lie mostly in the same flat disk around the Sun. It is like a big, thick-walled bubble made of icy pieces of space debris the sizes of mountains and sometimes larger. The Oort Cloud might contain billions, or even trillions, of objects.
When light leaves the Sun, it takes a little over eight minutes to reach Earth, and about 4.5 hours to reach Neptune’s orbit. Just under three hours after passing Neptune’s orbit, the Sun’s light passes beyond the outer edge of the Kuiper Belt.
After another 12 hours the sunlight reaches the heliopause, where the solar wind — a torrent of charged particles flowing away from the Sun at about a million miles per hour (400 kilometers per second) — smooshes up against the interstellar medium. Beyond this boundary is interstellar space, where the Sun’s magnetic field holds no sway. The sunlight has now been traveling away from the Sun for about 17 hours.
Less than one Earth day after leaving the Sun, the sunlight has already traveled farther from the Sun than any human-made spacecraft. Yet somehow it will be another 10 to 28 days before that same sunlight reaches the inner edge of the Oort Cloud, and perhaps as much as a year and a half before the sunlight passes beyond the Oort Cloud’s outer edge.
Unlike the planets, the main asteroid belt and many objects in the Kuiper Belt, objects in Oort Cloud do not necessarily travel in the same direction in a shared orbital plane around the Sun. Instead, they can travel under, over and at various inclinations, around the Sun as a thick bubble of distant, icy debris. Hence, they’re called the Oort Cloud rather than the Oort Belt.
Sedna: Is Sedna Our First Oort Cloud Object?

In their paper announcing the discovery of Sedna, Mike Brown and his colleagues described it as the first observed body belonging to the Oort Cloud.
The elliptical orbit of Sedna is unlike anything previously seen by astronomers. It resembles the orbits of objects predicted to lie in the hypothetical Oort Cloud--a distant reservoir of comets. But Sedna is 10 times closer than the predicted distance of the Oort Cloud. Brown speculated that this "inner Oort Cloud" might have been formed billions of years ago when a rogue star passed by the sun, nudging some of the comet-like bodies inward.
It ranges from its closest approach to the Sun at 76 AU and its aphelion estimated at 937 AU. That makes it one of the most distant-known objects in the Solar System other than the long-period comets. Some of Sedna’s orbit is within the AU distance of the inner Oort Cloud.
Several astronomers have already been calling Sedna a dwarf planet. To be a dwarf planet, Sedna must be in hydrostatic equilibrium. It is bright and large enough, that this is expected to be the case.
Inuit

The Inuit tribe is a native American tribe that settled near the Arctic. While they mostly reside in the northernmost parts of Canada, some Inuit groups settled in Alaska, Siberia, and Greenland as well. ''Inuit'' literally means ''the people'', and is the preferred term over Eskimos.
Brown initially nicknamed Sedna "The Flying Dutchman", or "Dutch", after a legendary ghost ship, because of its slow movement. For an official name for the object, Brown settled on "Sedna" which Brown chose partly because the Inuit were the closest polar culture to his home in Pasadena, He wrote: Our newly discovered object is the coldest, most distant place known in the Solar System, so we feel it is appropriate to name it in honor of Sedna, the Inuit goddess of the sea, who is thought to live at the bottom of the frigid Arctic Ocean.
It has triggered a new classification in astronomy called "Sednoids". Only three objects are known from this population: 90377 Sedna, 2012 VP113, and 541132 Leleākūhonua (2015 TG387), but it is suspected that there are many more.

A survivor of violent assault, romantic deception, and psychological abuse, Sedna’s depths of depression and fonts of rage and mistrust are as profound as the sea in which she lives.
The legend of how Sedna became a sea goddess is told throughout the Arctic. The story varies from one region to the next. However, in all versions, a young woman becomes the mother of all sea creatures. As the sea goddess, Sedna has dominion over her creatures and controls the availability of seal, walrus, fish, whale, and other sea animals to Inuit hunters.
Her transformation and empowerment at the end of the myth illustrates the potential of women to overcome male violence and strive for justice.
In our new myths it may illustrate how humanity can overcome violence and strive for equal justice.

Sedna’s orbit goes from normal to detached. This may be entirely because of small-scale interactions —and not because of a mysterious ninth planet. This belief may explain the dynamics of strange bodies called “detached objects”. Other scientists say no.
More unknown factors to learn?
In 2070 Sedna will return to its closest distance from the Sun. The last time Sedna was this close to the sun, Earth was just coming out of the last ice age. This after 11,500 years represents to astrologers an unrelenting power that simply will not allow crimes against Earth and her inhabitants to continue.
Climate change, artificial intelligence advances, and other theories are included in the speculation of how this might manifest.
