Two rocky exoplanets discovered orbiting nearby star Gliese 239

Star Gliese 239 lies 33 light years away. It is a red dwarf with half the mass and size of the Sun. Astronomers now report discovery of two transiting exoplanets, both bigger than the Earth but still rocky. They orbit very close to their star and have high temperatures on their surfaces.
