Earth-sized rocky planet found orbiting a nearby star

12 November 2015 Astronomy Now

The collection of rocky planets orbiting distant stars has just grown by one, and the latest discovery is the most intriguing yet. Known as GJ 1132b, the newfound world lies just 39 light-years away. Although hot as an oven, the 9,200 mile-wide planet is cool enough to potentially host an atmosphere. If it does, we could study that atmosphere in detail with the Hubble Space Telescope and future observatories like the Giant Magellan Telescope.
