Homonym: mercurio (Planet)
Mercurio is the smallest planet in our solar system and the closest to the Sun. It has a rocky surface covered with craters, similar to the Moon. Due to its proximity to the Sun, Mercurio experiences extreme temperature variations, ranging from very hot during the day to extremely cold at night.
Mercurio has a very thin atmosphere, which means it cannot retain heat. It takes about 88 Earth days to complete one orbit around the Sun. The planet is named after the Roman messenger god, known for his speed, reflecting Mercurio's quick orbit.
