The heliocentrism of the Planets.

Heliocentrism was born thanks to Copernicus, the book that dealt with this topic was published in 1543 where this model places the sun at the center of the universe, originally he thought that the sun was immobile, and now we know that it moves and that it revolves around The galaxy takes about 225 million years to produce a galactic year, which is what it is called.

The point is that initially it was thought that the orbits of the planets were circular, why the planets were spheres perfection, the circle is a perfect thing, then it was thought that the planets are spheres and the orbits are circular which is also a circle . It is a perfect geometric figure, but Kepler poured cold water on this perfect and perfectionist concept of the solar system and in 1610 he discovered that the orbits of the planets are more like ellipses.

The only one that approaches the perfect or almost circular circle is Venus, but all the other planets describe an ellipse, the sun is at one of its foci and is not perfect, for example, the difference between the point of maximum approach that By the way, it was on January 4 from the Earth to the sun, at the furthest point in its orbit from the Earth to the sun, which I think will be approximately July 5, there are approximately 4 million kilometers of difference, but of course for those wise men remained a little how it is that the stars had that imperfection why they don't have circular orbits, which would be perfect, the logical thing and that's it, we have elliptical orbits and that's it.

A month ago, research was published that is a hypothesis that has yet to be reviewed that could explain this anomaly. It was carried out by two scientists, one from the University of Toronto called Garett Brown and Renu Malhotra, in collaboration with the Planetary scientist of the University of Arizona Hanno Rein.

The study was published in December, the research is based on simulations and calculations with what would happen in a solar system with planets with originally perfectly circular orbits, if an object with a mass between two to 50 times greater than that of Jupiter passed between the planets, altering said orbits and leaving them as they currently are, they made 50,000 variations, so things were not easy at all.

They also studied the possibility of not only planets, but also that the solar system had passed very close to a star cluster, with which the gravity of that star cluster could have altered the orbits of the planets, the researchers found that the The best match with current orbits was that an object potentially a planet with a mass just over eight times that of Jupiter had passed through the solar system near the current orbit of Mars.

An object is mentioned because there are some astronomers who defend the existence of primordial black holes, they are theoretical objects, we have not yet found any primordial black hole, a primordial black hole is basically a black hole but it can be of any mass, they were supposedly formed during The beginning of the Big Bang then no longer formed, only at that moment a huge number of primordial black holes formed, is what this theory says.

These smaller primordial black holes would have evaporated due to Hawking radiation so they would no longer exist, but the calculation around the mass of the dwarf planet Ceres could exist, there could already be primordial black holes of that mass and of course there could be a primordial black hole with the mass of this study, eight times that of Jupiter, and if one of those passes through the solar system it could also cause that same deformation, because basically it has the gravity of a planet eight times that of Jupiter.

In the same investigation of the many simulations, it was determined that it had been calculated that one of the planets in the solar system could fall out of orbit in the next 20 million years. There are 2% of the cases in which this occurs, I suppose it will be Mars. , I have not been able to read the entire study, I suppose it will be Mars because it is the one with the most sensitive orbit of all, but this study still needs to go through peer analysis.
