-        The first confirmed planet discovered by volunteers, like you, on Planet Hunters was PH1b (also known as Kepler-64b). It is a Neptune-sized giant planet with a radius 6 times greater than that of the Earth. The really interesting thing about PH1b is that it’s a circumbinary planet, meaning it orbits around two stars! Those two stars are also in orbit around another binary star system, which makes PH1b the first planet ever discovered in a quadruple star system. Below is an artist’s impression of the system.

        Stellar flares may be spotted in the lightcurves on Planet Hunters. They are characterised by rapid spikes in brightness. These are large explosions from the surface of the star, just like the solar flares that we observe on our star the Sun. Below is an example of a lightcurve with flare features.

        The third confirmed exoplanet discovered by volunteers on Planet Hunters is in a system known as Kepler-90 and now has the designation Kepler-90h. This system already had six confirmed exoplanets, but the discovery of the seventh buy Planet Hunters volunteers made it the most populous planetary system known, apart from our own. The red circle in the diagram above shows the orbit of Kepler-90h in the system.
