As reported by the website Scientific news, at the beginning of the solar system’s formation the Sun may have had a companion star according to a new theory explained in a new study that appeared on Astrophysical Journal Letters.
According to the researchers, the Sun may have formed a binary system with a companion star of similar mass. This theoretical approach, among other things, would explain the formation of the Oort cloud and the theory according to which the eventual Planet Nine did not form within the solar system but would have been captured by its gravitational field.

And it is precisely on the Oort cloud that researchers have focused most. According to this new theory, most of the materials that make up today’s Oort cloud would have been captured from outside the solar system, which is facilitated by the presence of a second star. The most popular theory, on the other hand, explains the formation of this dense cloud full of gases and various materials, many of which are small, with the dispersion of smaller objects carried out by the gravitational force of the planets. However, a model of solar system formation that sees a binary system offers significant improvements to this theoretical approach according to Amir Siraj, a Harvard university student who worked with Professor Avi Loeb on this new theory.
On the other hand, as Siraj himself explains, many (most) of the Sun-like stars are found in a binary system and not alone. The second star would have made it possible for the Oort cloud to form before leaving the Sun. Understanding the origin of the Oort cloud itself is important as it is thought that the main asteroids that hit the Earth came from this area of the solar system, even the one that caused the extinction of, among others, dinosaurs and that changed the course of the very evolution of life on our planet, as Siraj suggests.
Furthermore, this theory seems to have implications also for the so-called “Planet Nine” or NIBIRU, a planet of the solar system that should be in the outermost periphery and which has never been intercepted (?) Precisely because it is so far away. This planet would have an impact, even in a rather marked way, at the gravitational level on the various “trans-Neptunian” objects of the most peripheral area of the same solar system.
Loeb and Siraj’s new theoretical model predicts a greater number of objects with an orbital orientation similar to that of the hypothesized Planet Nine, as Loeb explains. This is a theory that could also be confirmed shortly: the Vera C. Rubin Observatory, a large astronomical observatory currently under construction in Chile, could, once it becomes operational (perhaps as early as 2021), confirm this theory by verifyingor the existence of Planet Nine and the fact that it was gravitationally captured by the solar system from the outside.
The Nibiru Binary System
As discussed in the book “The Return of NIbiru”, a dark companion star of the Sun exists, where the massive disturbing planet NIBIRU or Planet X would orbit. Here is what is written:
“If this Sun’s (binary) companion star , a brown dwarf or red dwarf, were to arrive to cross a region close to the borders of our planetary system, we could seriously find one of its planets (precisely the one from the furthest orbit from this star) already inside the Solar System.
The exact position of this Planet X is mainly linked to the period of revolution that the star itself completes by orbiting around this companion star of the Sun, which, depending on the distance traveled in its orbit, would constitute the true thread between the Planet X and our Solar System.
Both stars move along very large orbits that would cyclically lead the Sun and its binary companion (i.e. a complete planetary system) to approach each other. The orbital periods of binaries can range from less than an hour to a few days, to hundreds of thousands of years.
We could therefore be part of a binary system in which the orbital periods make their own revolution over a time span of many thousands of years. ” Now to follow the announcement of some scientists who speak of the existence of Nemesis.
Gloi scientists announce: “The Sun has a ‘bad’ and dangerous twin and is called Nemesis, responsible for mass extinctions on Earth”
With a sophisticated mathematical model it has been shown that all stars form together with other sisters, a process that also involved our Sun. The discovery sheds new light on the existence of Nemesis, the twin of the Sun that could be responsible for the mass extinctions on Earth.
Researchers from the University of California (Berkeley) and Harvard University have shown with a mathematical model that all stars would be born in binary or multiple systems, consequently our Sun should also have had its twin. The scholars, coordinated by theoretical physicist Steven Stahler and radio astronomer Sarah Sadavoy, who follows Hubble on behalf of NASA at the prestigious Smithsonian Astrophysical Observatory, have practically dusted off the theory of Nemesis, the ‘bad’ twin of the Sun which cyclically – every 27 millions of years – would reappear at the edge of the solar system.
The star is called in this unflattering way because, according to some studies, many of which conducted in the late 1980s, due to the gravitational force it would bring with it dangerous comets capable of targeting the planets of the Solar System, including our Earth. Although there is no direct evidence, Nemesis would be responsible for the mass extinctions observed on our planet, which occur with a disturbing periodic cycle. Non-avian dinosaurs and other groups of animals, 64 million years ago, in the late Cretaceous, would be extinct precisely because of an asteroid “transported” by Nemesis.
Molecular cloud of Perseus, considered a real cradle for stars in formation
But let’s go back to the study that gave life back to this suggestive theory. Scholars have determined the non-solitary birth of stars thanks to the study of the molecular cloud of Perseus, considered a real cradle for stars in formation. Through the VANDAM mission, several young class 0 stars (less than 500,000 years old) and class 1 stars (less than a million years old) have been surveyed inside the cloud, which is 600 light years away from us.
Combining this data with other observations, the researchers identified 45 lone stars, 19 binary systems and 5 multiple systems. From the analysis of the distances, positions and distribution of the stars, through a mathematical model Sadavoy and colleagues came to the conclusion that they all originated from binary or multiple systems.
Nemesis, dinosaurs disappeared
Nemesis is hiding three light days away from us, or about 500UA
“Solar-type stars are not primordial – underlined Professor Stahler – but they are the result of the breaking of binary systems”. According to estimates, the Sun’s twin should currently be three light days away, or about 500UA (astronomical units, the distance between Earth and the Sun), hidden somewhere in the heart of the Milky Way.
Although it is defined twin, Nemesis could be a weak brown dwarf, reduced in this situation by the Sun which, during the accretion phases, would have stripped most of the dust and gas from it. Evidence of its existence, as specified, has never been found, however some think it can be read in the curious orbit of the dwarf planet Senda, influenced by the gravitational force of a mysterious celestial object. The details of the research were disclosed on arXiv.org and are awaiting publication in the authoritative scientific journal Monthly Notices of the Royal Astronomical Society.
The name of Nemesis, was proposed on the basis that this dark star “Killer” has an apparent cycle of 27 million years and would have been the cause of mass extinctions on Earth, including the one that saw the disappearance of dinosaurs .
An astronomer at the University of California at Berkeley named Richard Muller proposed a theory about 23 years ago that said a red dwarf was 1.5 light-years away and could periodically travel through the outer limits of our system. solar, mixing the material or trail of debris, planets, comets and asteroids with its gravity, creating planetary disasters in our part.
A faintly passing star like a brown dwarf could also explain other anomalies at the edge of our solar system, such as the strange, wide orbit of the dwarf planet Sedna.
