Gliese 581d, a rocky alien planet, may be the first known planet beyond Earth that meet key requirements for sustaining life, according to reports by several international news sites.
A new atmospheric-modeling study, performed by astronomers, reportedly found that Gliese 581d is located in a “habitable” zone similar to Earth with harboring oceans, clouds and rainfall.
The study concluded that Gliese 581d has been consistent with several other recent modeling studies. However, scientists cannot ultimately establish the presence of sustainable water across the planet’s surface.
Based on the study results, it is assumed that Gliese 581d has a thick, carbon-dioxide-based atmosphere.
According to reports, Gliese 581d, is an extra-solar orbiting the star Gliese 581. It is approximately 20 light-years away in the constellation of Libra. Gliese 581d is the third planet discovered in the system and the fifth in order from the star. Due to its enormous mass, approximately 5.6 times that of Earth, Gliese 581 is classified as a super-Earth.
