Planet Hunters find a planet with four suns

Volunteers taking part in the Planet Hunters citizen science project have discovered a planet with four suns [1]. This is the first of its kind discovered. The two discovers are Kian Jek of San Francisco and Robert Gagliano from Cottonwood, Arizona.

The planet is located just under 5,000 light-years away and has been named PH1 after the Planet Hunters. It is thought that PH1 is a gas giant, with a radius more than six times the radius of the Earth.
