The iron-rich asteroids, especially, should contain a high proportion of heavy elements that sank to Earth's core and are therefore very rare on Earth's surface (and consequently expensive). ertain enzymes or toxins candidates that aid in the penetration of or ingestion through plant surfaces. Pluto's gravity affects the orbit of Uranus, and this fact was used to discover Pluto. Falling stars and shooting stars are simply other names for meteors. Suppose that large jovian planets had never formed in our solar system. However, the high reflectivity can be explained by its large size; as volatile ices sublimate when Pluto approaches the Sun, Pluto's gravity holds them until they refreeze onto the surface.
