Far from the warm heat and glorious light of our sun, there is a dark and distant area inhabited by a frozen icy body well hidden from the curious observer’s pr cordy eyes. Indeed, astronomers have just begun exploring this strange area of ​​everlasting dusk, far away and not easily accessible to its many fascinating and bewitching secrets. This distant area at the outer limits of our solar system is called the Kuiper Belt, and the icy dwarf planet Pl and its quintet are the only ones in this area so far visited by spacecraft. I’m a resident. In June 2017, a planetary scientist at the University of Arizona in Tucson announced a new finding that the plane of the solar system is distorted at the outer edge of the Kuiper belt, revealing the possible existence of the world from Mars to Earth You are far beyond Pl Wonder. According to this new study of the asteroid’s orbit, published in the Astronomical Journal, this unknown and invisible “planet mass object” may be lurking farther away. This hidden, mysterious, icy world will be much closer, unlike the so-called Planet Nine, whose existence is still awaiting confirmation.

Kat Volk and Renu Malhotra, Ph.D. of the Moon and Planetary Research Institute (LPL) at the University of Arizona, present in a new research paper strong evidence that an undiscovered world boasts mass somewhere on Earth. And Mars. The authors show that this mysterious mass has abandoned its existence-so far-only by controlling the orbital surface of an icy cosmic rock mass known as the Kuiper Belt Object (KBO). And the frozen suburbs of our solar system.

Our solar system was born about 4.56 billion years ago. The frozen inhabitants of the distant Kuiper Belt are remnants of that ancient era. Most KBOs orbit our stars at an orbital inclination that averages what planetary scientists call the invariant plane of the solar system, but the farthest KBOs do not. In fact, Dr. Volk and Dr. Malhotra have found that the farthest of these frozen objects exhibit a mean plane that is inclined about 8 degrees from the invariant plane. This means that there is something unknown or strange to appear in this frosty distant shadow area that is distorting the mean orbital plane of the outer limits of the solar system.

“The most likely explanation for our results is that there is an invisible mass. According to our calculations, the measured warp needs to be as large as Mars.” Arizona press release on June 20, 2017. Dr. Volk is a postdoctoral researcher at LPL and the lead author of the research.

The Kuiper Belt is located beyond the orbit of Neptune and extends to hundreds of astronomical units (AU). One AU is the average distance between the earth and the sun, about 93,000,000 miles. In a manner similar to the main asteroid belt of the inner solar system located between Mars and Jupiter, the Kuiper Belt hosts a myriad of relatively small objects.

There are also some frozen asteroids hidden in the secret shadow of the Kuiper Belt. In this remote area of ​​dim light, our sun shines with only a faint star fire that can barely reach this frosty remote shadow area. Indeed, in this distant region of darkness, our sun swims in the sparkling sea and looks only like a particularly large star, swarming with countless other stars.

The Deep freeze of the solar system

The Kuiper belt is similar to the main asteroid belt, but it is quite large, about 20 times wider and 20 to 200 times wider than the asteroid belt. However, like the asteroid belt, the Kuiper belt has many relatively small objects. These are primitive remnants of the birth of the solar system. Many asteroids are composed of rock and metal, but most of KBO is composed of frozen volatiles (“ice”), such as water, ammonia, and methane. The Kuiper Belt also has officially confirmed asteroid trios, confirmed Uranus, Haumea, and Makeup. Some of the most mysterious moons in our solar system-such as Neptune’s Triton and Saturn’s Phoebe-are often thought to be bodies that originated from the Kuiper Belt but fled from its birthplace. Triton orbits Neptune backward. This is a moon that was truly captured by the powerful gravity of that beautiful blue-striped planet and clearly shows that it has only been adopted by the family. Triton orbited its adopted parent planet in the wrong direction, and someday wandered away from Kuiper’s frozen home, it was doomed to plunge into a thick blanket of clouds covering the orbiting blue planet. Will be. belt.

The Kuiper Belt was named after Dutch-American astronomer Gerald Kuiper, despite not predicting its existence. QB1 was detected in 1992 and 1992, and the first KBO has been discovered since the discovery of Pl Wonder in 1930 by American astronomer Clyde Tombeau. Since the discovery of 1992 QB1, the number of known KBOs has surged to over 1,000, and it is believed that there are more than 100,000 KBOs over 62 miles in diameter. Originally, astronomers thought that Kuiper Belt was the main home of periodic comets. A periodic comet has an orbit of fewer than 200 years (short-period comet). However, more recent studies since the mid-1990s have shown that the Kuiper belt is indeed dynamically stable and that the true birthplace of short-period comets is on the scattering disk. Scattered discs are dynamically active areas created by moving out of Neptune 4.5 billion years ago. Scattered disk objects such as Ellis boast a highly eccentric orbit that carries them up to 100 AU away from the Sun.

Another distant house of the solar system comet is still hypothetical Oort cloud. The Alt Cloud is thought to be about 1000 times distant from the Kuiper Belt and is mostly spherical. The distant inhabitants of the Kuiper Belt, along with the frozen inhabitants of the scattered disks, are called Neptune Objects (TNO). The icy d-star-planet Pl is the largest and heaviest component of the Kuiper Belt. It is also the second-largest known TNO after Ellis, living in scattered disks. Although Pl was originally classified as a major planet, it was abruptly displaced from the major solar system planet Pantheon in 2006 to be reclassified as a d-asteroid. In composition, Uranus resembles many other KBOs and orbits, a period that is characteristic of a particular class of KBO called “Plutino”. A plutino is an object that shares the same 2: 3 resonance with Neptune.

The mysterious world is hidden beyond Pl Uranus

In a recent paper, Dr. Volk and Dr. Malhotra analyzed the inclination of the orbital plane of more than 600 remote icy objects inhabiting the Kuiper Belt. Two planet scientists have done this to determine the common direction in which this frozen world lets all precess. Precession is a term used to describe a change in direction or “wobble” of a rotating body.

“Imagine a lot of fast-rotating tops, each of which is tweaked a little. When you take snapshots of them, their axes of rotation will be in different directions, but on average, Gravitational field, “explained Dr. Malhotra in a University of Arizona press release on June 20, 2017. Dr. Malhotra is a professor of scientific research at Louise Hooker Marshall and a Regent Professor of Planetary Science at LPL.

“The orbital inclinations of the KBO are expected to be in different directions, but on average will be perpendicular to the plane defined by the sun and the large planets,” she added.

Imagine the mean orbital plane of objects in the outer solar system as a sheet. According to Dr. Volk, it should be very flat after 50 AU.

“But going further from 50 AU to 80 AU, we found that the mean surface actually warped from the invariant surface. There are various uncertainties in the measured warpage, but this is unlikely Less than 1 percent or 2 percent. Warp is just a statistical fluke of KBO’s limited sample of observations, “Dr. Volk explained in a press release from the University of Arizona on June 20, 2017.

This means that the effect is probably not a statistical problem, but a real signal. According to new calculations, an object of the same mass as Mars orbiting about 60 AU from the Sun in an orbit inclined about 8 degrees with respect to the average plane of a known planet will exert a sufficiently strong gravitational effect, Orbital surface of remote KBO within about 10 AU on each side.

“The observed distant KBO is centered on a ring about 30 AU in width and will feel the gravity of such a planetary mass over time, so one planetary-mass will cause the observed warpage It is not unreasonable to assume that over the distance. “

This observation excludes the possibility that the proposed object is a virtual planet 9. The possible existence of Planet Nine is based on other observations. The planet is predicted to be about 10 times as massive as Earth and far from 500 to 700 AU.

“It’s too far to affect these KBOs. To effectively affect the range of KBOs, they must be much closer than 100 AU,” Dr. Volk added.
