The article make it seem like this is a new discovery which is not the case: According to <a href="https://en.wikipedia.org/wiki/Kepler-186f" rel="nofollow">https://en.wikipedia.org/wiki/Kepler-186f</a> it was discovered in 2014
Kepler-186 is a red dwarf <a href="https://en.wikipedia.org/wiki/Kepler-186" rel="nofollow">https://en.wikipedia.org/wiki/Kepler-186</a><p>The planet is therefor closer to its star but apparently it may not be tidally locked:<p>> The four innermost planets are probably tidally locked, but Kepler-186f is in a higher orbit, where the star's tidal effects are much weaker, so the time could have been insufficient for its spin to slow down significantly.<p><a href="https://en.wikipedia.org/wiki/Kepler-186f" rel="nofollow">https://en.wikipedia.org/wiki/Kepler-186f</a>
If we would achieve 99.9999 of light speed, we could get there in just under a year (288 days).<p><a href="https://www.emc2-explained.info/Dilation-Calc/" rel="nofollow">https://www.emc2-explained.info/Dilation-Calc/</a><p>I hope it would look more like the first picture instead of like the second.
