We report the discovery of a new exoplanet candidate orbiting the star GJ
3470. A total of three transits were detected by OKSky Observatory: the first
one on December 23, 2019, the second one on February 27, 2020, and the third
one on May 3, 2020. We estimate an average transit depth of 0.84 percent and
duration of 1 hour and 2 minutes. Based on this parameter, we calculate a
radius of 9.2 Earth radii, which would correspond to the size of a Saturn-like
exoplanet. We also estimate an orbital period of 66 days that places the
exoplanet inside the habitable zone, near the orbital distance at Earths
equivalent radiation. Another twelve potential transits that do not belong to
GJ 3470 b are also reported. Despite our candidate for GJ 3470 c still has to
be confirmed by the scientific community, the discovery represents a turning
point in exoplanet research for being the first candidate discovered through an
international project managed by amateur astronomers.
