The exoplanet, which is called GJ 3470 b, is a mini-Neptune with an orbital period of 3.3 days.
In July 2020, a group of amateur astronomers reported a new exoplanet candidate, which is the size of Saturn and inside the system's habitable zone, along with twelwe tentative transits from not yet characterized exoplanets in same star system. If confirmed, GJ 3470 c would become the second exoplanet discovered by amateur astronomers, after KPS-1b, an exoplanet discovered by Ural State Technical University using amateur data. The new GJ 3470 candidate was discovered with amateur data and through a project led by amateur astronomers.
