This is part of a whole solar-system model that spans central Florida.
Mercury is the quick-moving messenger god, and the element mercury is often a fluid substance known as quicksilver. Mercury the planet is the closest planet to the Sun, and its gravity yanks it around it in a fast year that’s 88 earth days long. Even though it’s closest to the sun, Mercury is not the hottest planet; that title goes to the next planet out, Venus, which has runaway greenhouse gasses capturing energy. Mercury’s diameter is 4880km⁘, and its orbital distance from the Sun is 57,910,000km or 0.39AU or 3.2 light-min⁘.
The model of Mercury is 6.3cm in diameter⁘, and is about 749.15m distant⁘ from the fountain dome in Lake Eola Park.
