Earth-Like Planet Found in Nearby Star System?

Earth-Like Planet Found in Nearby Star System?

     (Phys.org)—An Earth-like planet may be lurking in a star system located just 16 light years away, according to a new research. The star, named Gliese 832, was recently investigated by a team of astronomers searching for additional exoplanets that may be residing between the two currently known alien worlds in this system. A paper detailing the finding was published online on Apr. 15 in the arXiv journal.

Gliese 832 is a red dwarf and has just under half the mass and radius of our sun. The star is orbited by a giant Jupiter-like exoplanet designated Gliese 832b and by a super-Earth mass planet Gliese 832c. The gas giant, with a mass of 0.64 Jupiter masses, is orbiting the star at a distance of 3.53 AU, while the other planet is potentially a rocky world, around five times more massive than the Earth, residing very close its host star—about 0.16 AU.

Now, a team of astronomers, led by Suman Satyal of the University of Texas at Arlington, has reanalyzed the available data on this nearby planetary system hoping to find more extrasolar worlds that may be located in a vast space between the two known planets. [...]
