The Inner Planets: Mercury

The video explores Mercury's extreme temperature variations, being the planet with the greatest temperature range in the solar system. It is the second smallest planet, about one-third the size of Earth. In 1974, NASA's Mariner 10 spacecraft provided the first close-up images of Mercury, revealing a heavily cratered surface with high cliffs and expansive plains. Mercury orbits the sun quickly, completing a revolution in 88 Earth days, but rotates slowly, taking 59 Earth days for a full rotation, resulting in long days and nights.
