The Expolanet Kepler-186f apparently has a stable axis of rotation and therefore reliable seasons.

For decades, humanity has been searching for so-called exoplanets, including the conditions could allow the emergence of life. With Kepler-186f, in 2014, such an exoplanet was discovered at a distance of about 500 light-years, which is closer to Earth than previously thought. Although Kepler-186f is slightly larger than our Earth, there are apparently stable seasons. In 130 days, Kepler-186f revolves around its sun, a red dwarf in the Schwan constellation.
Also the inclination of the axis of rotation is
according to scientists at Georgia Institute of Technology in Atlanta
very stable. This ensures a stable climate and regular seasons without too much of an extreme. But not only Kepler-186f fulfills these characteristics, but Kepler-62f at a distance of 1200 light-years should have a stable inclination of the axis of rotation. The importance of this axis shows our neighbor Mars: In its history, the tilt of the axis of rotation fluctuated between 0 and 60 degrees. This caused the wet March three billion years ago lost its atmosphere and thus became a very hostile environment. The axial slope of a planet determines the amount of light that strikes the surface. A steep axial slope ensures extreme temperature differences between the North Pole and the South Pole.
