Exoplanet Explorers was a Zooniverse citizen science project aimed at discovering new exoplanets with Kepler data from the K2 mission.[1] [2] The project was launched in April 2017 and reached 26,281 registered volunteers. Two campaigns took place, the first one containing 148,061 images and the second one 56,794 images.[3]
A total of 9 exoplanets were found through the project: K2-138 b, c, d, e, f and g (initially referred to as EE-1b, EE-1c, EE-1d, and EE-1e), K2-233 b, c, and d, and K2-288Bb. K2-288Bb is considered to be potentially habitable with a radius of 1.91 Earth radii and a temperature of 206 K.[4]
Several other candidates in size groups were also found: Jupiters: 44, Neptunes: 72, super-Earths: 53, Earths: 15.[5]
