Another hypothesis is that the monster planet comes from a completely different solar system, with the planet moving towards the star, which is near it. From the side it seems as if the cosmic bodies are connected. But this theory was destroyed by mathematical calculations.
However, the researchers discovered another mysterious feature of the planet. Its orbit. As already mentioned, it is incredibly large, 22 times larger than our planet Neptune. The orbit around its mother star takes about 1500 years but this is not unusual,what is unusual is the following: most planets orbit around their stars on slightly elliptical orbits, but the orbit of HD 106906 b is not really elliptical circular, it is an incredibly elongated ellipse.
The mega planet is a good 97 billion kilometers away on the main axis of the ellipse, while it comes very close to the star on the side axis. But that's not possible mathematically. Such orbits are characteristic for so-called ghost-objects like asteroids and comets but not for such giants.
The unusual rotation allows only one explanation: the planet is an foreigner, i.e. it was ejected by another solar system and fell into the gravitational field of the star HD106906. Here he was attracted to it and attained the strange elongated orbit. The problem of the theory: HD 106906 b is incredibly young, only 13 million years old, a baby therefore. In his short life it would have been impossible to have flown to this place.
There are simply no other suns and planetary systems nearby. So what is there? Since it is apparently impossible to find an origin for this giant, a completely different question arose in front of the astronomers: Is that a planet at all? Maybe it is something completely different?
If we assume that this giant is not really a planet but a star, suddenly everything fits together! Together with another star, they come from a gas cloud and revolve around a common mass center. A double star system would be explainable but not with these colossal mass differences.
In the universe there are countless double star systems but the mass difference must not exceed ten times. This celestial body however is 100 times more weightless than its mother-star.
The researchers put forward another theory. What if this body were a failed star, also known as a brown dwarf? But that doesn't fit either. To be a brown dwarf, a heavenly body must reach thirteen times the size of Jupiter and in this case the object is only eleven times as big.
However, there is another hypothesis that could explain the mysterious origin of HD 106906b.
