The orbit of Mercury has the highest eccentricity of all the Solar System planets, and it has the smallest axial tilt. Other than that, it is an unremarkable small and dense world with almost no atmosphere.
65% of the planet is comprised of its metallic core. Consequently this planet has the highest proportion of metals to it's mass of all the planets in the solar system (ignoring metallic hydrogen).
