Exoplanet Has A Stable Axis Just Like Earth

Of all the exoplanets, planets outside of Earth's solar system, discovered in recent years, one that's captured some of the most attention is Kepler-186f. It's often described as one of the "most Earth-like" of all exoplanets discovered and a new study just adds to the case. A new look at Kepler-186f's axial tilt, also known as obliquity, is stable just like Earth's … Researchers at Georgia Tech looked at the relationship between Earth and Mars to better understand Kepler-186f … “It appears that both exoplanets are very different from Mars and the Earth because they have a weaker connection with their sibling planets. We don’t know whether they possess moons, but our calculations show that even without satellites, the spin axes of Kepler-186f and 62f would have remained constant over tens of millions of years.” says Gongjie Li, a professor who led the study, in a press statement. Li is an assistant professor in the School of Physics. Several other outlets have picked up the story: Popular Science, CNET, MSN, Newsweek, New Atlas, and SciTech Daily.
