🪐 Quick Facts about Mercury Position from the Sun: 1st Average distance from the Sun: ~58 million km (36 million miles) Diameter: 4,880 km (3,032 miles) Length of a day (rotation): ~59 Earth days Length of a year (orbit): ~88 Earth days Moons: None Atmosphere: Extremely thin (exosphere), mostly oxygen, sodium, hydrogen, helium, and potassium Temperature range: Day: up to 430°C (800°F) Night: down to -180°C (-290°F) 🔭 Interesting Facts Mercury has no atmosphere to trap heat, which causes huge temperature swings. It has a large iron core, making up about 85% of the planet's radius. Surface features resemble the Moon: lots of craters, ridges, and plains. Mariner 10 and MESSENGER are the main missions that have studied it. A new mission, BepiColombo, launched by ESA and JAXA, is en route and will arrive in 2025.
