I just wonder what these climates are like and of course, the resulting landscapes. Too bad they're so far away and our technology sucks.

"It appears that both exoplanets are very different from Mars and the Earth because they have a weaker connection with their sibling planets," Li says.
"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."
Kepler-186f is less than 10 percent larger in radius than Earth, but its mass, composition, and density remain a mystery. It orbits its host star every 130 days.
According to NASA, the brightness of that star at high noon, while standing on 186f, would appear as bright as the sun just before sunset here on Earth.
Kepler-186f is located in the constellation Cygnus as part of a five-planet star system.
