A newfound alien world might be able to support life – and it’s just a stone’s throw from Earth in the cosmic scheme of things. The planet, known as Gliese 832c, lies just 16 light-years from Earth. Gliese 832c is a “Super-Earth” at least five times as massive as our planet, and it zips around its host star every 36 days. “The Earth Similarity Index of Gliese 832c is comparable to Gliese 667Cc and Kepler-62e,” Mendez wrote in a blog post today. Gliese 832c is the second planet to be discovered around the star Gliese 832.
“So far, the two planets of Gliese 832 are a scaled-down version of our own solar system, with an inner, potentially Earth-like planet and an outer, Jupiter-like giant planet,” Mendez wrote.
“Given the large mass of the planet, it seems likely that it would possess a massive atmosphere, which may well render the planet inhospitable,” Wittenmyer and his team wrote in their paper, which has been accepted for publication in The Astrophysical Journal.
