Metals are everywhere in the Universe, from hot gas giants where it rains molten iron to heavy elements formed as a star goes supernova. Exoplanet GJ 367b one-ups them all. This planet is made <\/i>of metal.<\/p>\n

GJ 367b<\/a> is an extreme planet. This \u201csuper Mercury,\u201d which orbits its star once every 7.7 hours, was first discovered by NASA\u2019s TESS<\/a> planet hunter in 2015. Now, scientists from the University of Turin in Italy and the Th\u00fcringer Landessternwarte in Germany have examined more recent measurements of the planet using ESO\u2019s HARPS spectrograph<\/a> along with the original TESS observations. They found that this object is almost twice as dense as Earth\u2014which suggests it is most likely made of solid iron.<\/p>\n

Even though GJ 367b is now a solid iron planet, it might have once been the core of an ancient rocky planet.<\/p>\n<\/div>\n
