An artist’s rendition of interior compositions of planets around Kepler-102 and Kepler-407. The picture shows what minerals are likely to occur several different depths. An exoplanet in orbit around Kepler-102 is Earth-like, dominated by olivine minerals, whereas a planet around Kepler-407 is dominated by garnet, so less likely to have plate tectonics.
