Though NASA has confirmed3,440 planetsoutside our solar system , no one has ever been able to sustain an exomoon . While we know they ’re out there , huddling around their various planets , Modern inquiry could clue us into why we have n’t been able to find one yet — and it could be because their planets are assholes .
A squad ofresearchersat Nanjing University in China have been running simulations of exoplanets , their stars , and their theoretical moon , based on exoplanets scientist have already confirmed . These exoplanets incline to revolve their stars very closely — much closer than Earth orbits our own Sun .
In the computer simulation , the squad gave each exoplanet 500 synodic month . The group found that over time , pic vaporization from high vigor photons — due to the exoplanet orbiting the host genius so closely — force the exoplanets to lose some of their atmospheric mass . As a result , the exoplanets also lost some of their gravitational pull , make their exomoons to infix an elliptical , unstable orbit that ultimately reserve them to scat the electron orbit altogether . By the end of each simulation , very few moons — if any — remained . The team ’s findings werepublishedon December 1st , 2016 in The Astrophysical Journal .
The researchers establish that once exomoons were kicked out of their planets ’ friendzones , their destiny varied . Some becamerogue planets , digress the galaxy alone , free-swimming to any headliner . Some of the other moons that remained in cranial orbit ended up colliding with their host planets .
Hopefully , the studywill serveas a civilised warning to those search for exomoons : Do n’t look at planets that revolve too nigh to their suns . They ’re jerks .
