What is the most common synonym for "planet" bridging general understanding and astronomical reality?

Answer

World

The term 'World' is cited as the most straightforward alternative to 'planet' and is frequently used when referring to Earth, carrying an immediate sense of place and scope encompassing everything known or inhabited. This usage aligns closely with the casual reference to Earth as 'our planet.' While other terms like 'Celestial Body' are broader astronomical descriptions, and 'Sphere' focuses only on shape, 'World' effectively bridges the gap between the common, ground-level understanding and the astronomical fact that this specific world is one of several orbiting a star. It is highlighted as the most common 'other name' sought in immediate, universally understood synonym searches.
