Tidal forces of neighbors could make the three planets of the TRAPPIST-1 system habitable

TRAPPIST-1 is one of the most interesting planetary systems to study, which is still open. It is located just

40 light years from Earth, and from seven planetsthe size of ours at least three can be inhabited. One of the oddities of this system is that all seven of its planets, named from TRAPPIST-1b to -1h, are in orbit in close proximity to the star and from each other. In other words, they could well fit in the space between Mercury and the Sun.

They are also very close to their star,which ejects far more high energy particles than our sun. This radiation can destroy the complex molecules necessary for the origin and development of life.

During the research system, scientists discoveredthat the two closest to the star of the planet TRAPPIST rotate close enough to each other so that they can create powerful tides. At the same time, tidal forces are so powerful that they are able to maintain volcanic activity on both space bodies. This, in turn, allows you to save the atmosphere on both planets.

Earlier, astronomers from the La Silla observatory team in Chile, on the EULER telescope, discovered five exoplanets with record periods of rotation around their star for more than 15 years.
