[5] It orbits on the inner edge of the habitable zone of a red dwarf, Kepler-438, about 460.2 light-years from Earth in the constellation Lyra.
However it has been found that this planet is subjected to powerful radiation activity from its parent star every 100 days, much more violent storms than the stellar flares emitted by the Sun and which would be capable of sterilizing life on Earth.
[11] Researchers at the University of Warwick say that Kepler-438b is not habitable due to the large amount of radiation it receives.
The Kepler spacecraft can only focus on a small, fixed region of the sky, but the next generation of planet-hunting space telescopes, such as TESS and CHEOPS, will have more flexibility.
Exoplanetary systems, with stars less distant than Kepler 438, can then be studied in tandem with the James Webb Space Telescope and ground-based observatories like the future Square Kilometer Array.
