All of these new planet candidates are located far from their host stars. In fact, seven of them lie in their host star\u2019s habitable zone. Unfortunately, all of these planets are too large to be Earth-like.<\/em><\/p>\n<p style=\"padding-left: 30px;\"><em>Two of the new planet candidates are in multiple candidate systems. One of them, the new candidate orbiting KOI-351, is the<a href=\"http:\/\/blog.planethunters.org\/2013\/11\/04\/exploring-the-tiny-planetary-system-of-koi-351\/\">\u00a0seventh planet candidate<\/a>\u00a0orbiting its host star. Planet Hunters actually detected three new candidates around this star when KOI-351 was only known to have three candidates, showing how great the Planet Hunters can be in discovering multiple planet systems. The planets in KOI-351 also show strong gravitational interactions between the planets, which helps to confirm them as true planets. The gravity from some planets in the system causes other planets to transit before or after what we would otherwise expect, called transit timing variations. In fact, the second-to-last planet transited a full day after we expected it would. Others in the exoplanet field have been working for over a year to determine the masses of these planets.<\/em><\/p>\n<p>The paper and contributors to the project:<\/p>\n<ul>\n<li><a href=\"http:\/\/arxiv.org\/abs\/1310.5912\" target=\"_d\">Planet Hunters.
