What is the name of the exoplanet noted to rival Mercury’s metallic leanings?

Answer

GJ 367 b

While Mercury holds the title among the eight established planets in our Solar System, astronomers have identified exoplanets exhibiting similar iron-rich characteristics orbiting other stars. A notable example mentioned is GJ 367 b, a world situated approximately 31 light-years away. This exoplanet, although smaller and less massive than Earth, appears to be largely composed of iron, closely mirroring the high metallic composition observed in Mercury. The existence of GJ 367 b suggests that the formation mechanisms leading to iron-rich terrestrial worlds are not exclusive to our immediate solar neighborhood.
