        PH2b is the second planet discovered by volunteers on Planet Hunters. It is a Jupiter-sized, gas giant planet in orbit around a star very similar to our Sun. It’s orbit is only 17% smaller than that of the Earth, putting it in a region known as the habitable zone, the distance from a star where the conditions may be right for life. You will learn more about the habitable zone later. Below is an artist’s impression of the view from a hypothetical habitable moon in orbit around PH2b

        The idea of planets orbiting other stars in our galaxy has been around for hundreds of years (in fact 16th century Italian astronomer Giordano Bruno was burnt at the stake at least in part for his beliefs on the matter!). However, it was not until 1992 that the first exoplanet was confirmed. It was found orbiting a pulsar, the rapidly-spinning, dense core of a dead star. The first confirmed planet orbiting a Sun-like star, 51 Pegesi b, was announced in 1995. Since then over one thousand exoplanets have been confirmed and many more candidates identified. The graph below shows the distribution of planet candidates discovered by the Kepler mission as of November 2013.
