How many abandoned planets are there in our galaxy?
The planets, which themselves are wandering in space, astronomers call these lonely Wanderers, these individuals in our galaxy, according to us astronomers is approximately 50 billion. These planets for some reason were thrown out by their stars for the chapels of their influence and now the planets are flying to where they were originally sent by the velocity vector. Scientists came to this conclusion after analyzed on a computer one of the star clusters. It turned out that a quarter of the stars in this cluster as it turns out loses one or even two planets, all due to the gravitational interaction of close-standing stars.
Planets at a great distance easier to see if they are near the stars, there are many ways to see these planets, but when the planet is flying in space in splendid isolation and unaccompanied, it is seen at a great distance is very difficult, but with the modern development of technology is still sometimes solved. I recently discovered a planet solo from the Earth at 100 light-years, named this strange planet CFBDSIR2149. According to experts, this planet is much larger in mass than Jupiter, about the mass of our seven Jupiters, just a huge planet. It flies from the star cluster AB Golden Fish. Probably when she was born there.
Perhaps you still wonder, and from where so many planets in space alone? The whole thing probably young star clusters, those clusters where the stars are fairly close to each other and it can affect the planet to each other. It turns out that the neighboring star, under favorable circumstances, may well tear off her planet from her companion, but not keep her at home for a number of reasons. And then just born a new wandering planet, a planet without heat and its sun.
Probably interested to know how often this could happen? It was the desire to know this that prompted scientists to create a special program to analyze a very densely populated star cluster, which is only a little more than 1000 light years. This cluster is located in the night sky not far away, in the Orion nebula. Scientists have suggested that a third of the stars in this cluster have several planets. Then astronomers looked at the development of planets and stars for 11 billion years, all so to speak quickly scrolled. And it turned out that there are simply no sterile conditions in space, all the planets develop as a rule with the participation of some cataclysm.
And star neighbors affect, and collision with planets also affects, and even close gravitational interaction sometimes greatly changes the trajectory and life of the planet in the future. In fact, in their study, scientists have confirmed the hypothesis about the influence of close stars and planets on each other. What numbers came out this might all be nothing more than a fantasy, but the fact that the proximity of neighboring stars in the active form affects the number of lone planets in the constellation or who no longer denies.
Some planets changed orbit, what is encountered, but there is quite a high percentage of these planets that just flew outside the attraction. Many planets even flew away and does not affect such a coincidence nor the mass of the planet and its location relative to the star, all the reason the case.
If the theory is true, it turns out that in our galaxy wanders about 50 billion single planets.
How and in what way scientists have calculated this number remains a mystery, it can be slightly on accuracy far-fetched, but still very plausible. In our galaxy there are about 200 billion stars, every third star has a planet and not even one, so based on the mathematical probability and analysis of the previous problem, it turns out that in our galaxy of abandoned planets about 50 billion.
Our Solar system also at some stage was influenced by an alien star and by the way the debris in the Kuiper belt behave, scientists found out that this apparently happened 70 thousand years ago. This star also to some extent reshaped the orbits of planets and large asteroids, perhaps even something thrown out of our planetary system. Can be the hypothesis of a binary system in the Solar system is also true and the Raja of the Sun when it was shining in the sky... All can be, can be even and such, that space there is no, and earth flat, so at least argues in their lectures academic Tyunyaev...
