An exoplanet twice the size of Earth, known as Wolf 503b, has been found just 145 light-years away from our home planet.

The researchers noted that Wolf 503b is interesting not only because of its size (it may potentially be a “Super-Earth”), but also because of its orbit — it revolves around its star once every six days.

An exoplanet is a planet outside our solar system.

“Wolf 503b is one of the only planets with a radius near the gap that has a star that is bright enough to be amenable to more detailed study that will better constrain its true nature,” said Björn Benneke, a UdeM professor, in a statement. “It provides a key opportunity to better understand the origin of this radius gap as well as the nature of the intriguing populations of ‘super-Earths’ and ‘sub-Neptunes’ as a whole.”
