The Kepler space telescope, though he had some incidents that worried the NASA scientists, the telescope returns to the fore despite all problems bringing new elements for life on other planets. Mission of this telescope is searching for solar systems similar to our own and planets like Earth.

The space telescope data collected by a group of four who exoplanets in orbit around a red dwarf (Hertzsprung-Russel diagram) The name has been given by scientists K2-72. Its distance from Earth is 181 light years away in the constellation Aquarius. Four overall planets is 20% to 50% larger than the Earth, while two of them, and K2-72c K2-72e placed in so-called habitable zone. They are located in a circular orbit around their star at a distance sufficient for the existence of water in liquid form which enables them to support and accommodate life.

The position of these two planets in relation to the red dwarf makes the habitable zone close to him in relation to the Earth and the Sun. The K2-72c to make a full rotation around the K2-72 takes 15 Earth days and is only 10 degrees Celsius hotter than the Earth. The K2-72e makes a complete rotation every 24 days and is 6% colder.
