Like the Sun star can have up to seven potentially habitable planets, but on the condition that this system is not gas giants like Jupiter. To such conclusion astrobiologist Steven Kane from the University of California, riverside, reported on the website of the University.

the Scientist had been studying one of the nearest to us star systems are called “Trappist-1,” which in the habitable zone (where possible the presence of liquid oceans) are just three exoplanets.

– This got me thinking about the maximum number of habitable planets, which can be a star and why the Sun has only one planet, noted Kane. It struck me as unfair!

His team with the help of mathematical modeling was to study how planets in various combinations – varied the number and size of celestial bodies, their orbits. The algorithm took into account gravitational forces and helped to check how the planet could communicate with each other over millions of years. In the end, scientists came to the conclusion that some stars can have up to seven exoplanets with liquid water, and the Sun, potentially able to “contain” six of these planets.

– When planets in the habitable zone of more than seven, they are too close and destabilisateur orbit each other; said Kane.

as for our Solar system, it only has one habitable planet because of Jupiter. Ideally, the orbits of the planets must be round, they do not intersect with each other, and the huge Jupiter (its mass is two and a half times more than all other planets of the Solar system) of its gravity disrupts the “correctness” of the orbits of the other planets.
