Called GJ 1132b, the exoplanet is located 39 light-years from Earth and is the closest Earth-size planet of its kind, scientists say. In fact, the planet may be a potential twin of Venus.
GJ 1132b is about 9,200 miles (14,800 km) wide and has a mass that is abotu 1.6 times that of the Earth. It circles its planet superfast, completing a single "year" in about 1.6 Earth days. Its orbit brings it closer to its parent star than Mercury is to our sun.
