Planet Mercury is the smallest and innermost planet in the Solar System. It is the closest planet to the Sun, with an average distance of about 57.91 million kilometers (36 million miles). Mercury has a rocky body and a thin atmosphere, primarily composed of oxygen, sodium, hydrogen, helium, and potassium. Due to its proximity to the Sun, it experiences extreme temperature variations, with daytime temperatures soaring up to 430 degrees Celsius (800 degrees Fahrenheit) and dropping to -180 degrees Celsius (-290 degrees Fahrenheit) at night. Mercury has a heavily cratered surface, resembling that of the Moon, indicating that it has not undergone significant geological changes for billions of years. It has no moons and does not possess any rings. Mercury’s orbital period around the Sun is approximately 88 Earth days, which means it has a short year compared to other planets. The planet is named after the Roman messenger god, Mercury, known for its speed, which reflects the planet’s quick orbit. Mercury is of interest to scientists and astronomers for its unique properties and history, including its role in the formation of the Solar System.
