Answer» Scientists have discovered a hot, metallic, Earth-sized planet-"K2-229b"- orbiting a dwarf star located 260 million light-years away. The planet is almost 20% larger than Earth but has a mass which is over two-and-a-half times greater. K2-229b is also the innermost planet in a system of at least three planets, though all three orbit much closer to their star than Mercury.
