EARTH (B)

Symbol of the globe of the Earth crossed by its equator and meridian

Considered the spherical center of the world in antiquity and a planet only since the Renaissance, Earth's symbol expresses its centrality and is still used in surveying. It is the first planet to be explored directly, and became the prototype for understanding solid planetary bodies. Later, it was explored by spacecraft from a distance, much as the other planets had been observed for centuries.
