The Solar System’s Innermost Planet
Mercury, our solar system’s tiniest planet, orbits near the sun, basking in intense heat. This proximity renders it largely invisible until the moments right after sundown or just before dawn. It’s a world of extremes, positioned at the brink of daylight and darkness, encapsulating the stark contrasts of our cosmic neighborhood.

Captured by the pioneering MESSENGER spacecraft, the first to orbit Mercury, this detailed image unveils the planet’s surface, hinting at an unusual internal structure and a tumultuous past. It tells a story of geological surprises and processes that have shaped this little planet, offering clues about the early solar system’s history.
