K2-288Bb is located 226 light-years from us, in the constellation Bull and part of the star system, which contains two smoke stars, about 5.1 billion kilometers apart. One of the stars is half as big as the sun, while the other one is about a third of the size of the sun. The research group found that the new planet encircles the smaller star every 3.1 days. Depending on the supporting paper of discovery, this star is theoretically capable of maintaining biosphere with the same productivity as Earth.
We discovered the planet primarily because of the volunteers who studied light curve data with Kepler's own eyes, but not with the help of software. Volunteer scientists from the Citizens' Program named Exoplanet Explorers could observe a planet missed by program algorithms. Adina Feinstein, lead author of the study, said that "she needed the sharp eyes of civil scientists to make this extremely valuable find and direct us to it."
