Here are ten super facts about Mercury:
Mercury is the smallest planet in the Solar System, with a diameter of only 4,880 kilometers (3,032 miles).
It is also the closest planet to the Sun, orbiting at a distance of about 58 million kilometers (36 million miles).
A year on Mercury (the time it takes for one orbit around the Sun) is only 88 Earth days, while a day (the time it takes to rotate once on its axis) is about 59 Earth days.
Due to its proximity to the Sun, Mercury has a very thin atmosphere consisting mostly of helium, hydrogen, and trace amounts of other gases.
Mercury is heavily cratered and has a rocky, barren surface with deep canyons, mountains, and plains.
It has no moons or rings, and its magnetic field is about 1% as strong as Earth's.
Mercury has the greatest temperature variation of any planet in the Solar System, with daytime temperatures reaching up to 430°C (800°F) and nighttime temperatures dropping to -180°C (-290°F).
The planet is named after the Roman messenger god, Mercury, who was known for his speed and agility.
Only two spacecraft have ever visited Mercury: NASA's Mariner 10 in the 1970s and the Messenger spacecraft, which orbited the planet from 2011 to 2015.
In 2018, NASA launched the BepiColombo mission, a joint mission with the European Space Agency, to study Mercury's composition, magnetic field, and geology in detail.
