SURFACE GRAVITY – Mercury’s surface gravity is 38% of Earth’s, due to its smaller size and mass.

MERCURY’S TILTED AXIS – Mercury has a very small axial tilt (about 0.034°), meaning it doesn’t experience seasons like Earth.

SURFACE FEATURES – Mercury’s surface is covered with craters, ridges, and plains, with many similarities to the Moon’s surface.

MERCURY’S DAY AND YEAR – A single day on Mercury lasts 59 Earth days, while a year lasts only 88 Earth days.

MAGNETIC FIELD – Mercury has a weak magnetic field, likely generated by a partially molten iron core.

SCARPS – Long cliffs on Mercury’s surface caused by the planet’s contraction as it cooled, indicating that it has shrunk slightly.

CALORIS BASIN – A large impact crater on Mercury, one of the largest in the solar system, formed by a collision early in the planet’s history.

EXTREME TEMPERATURES – The surface temperature of Mercury ranges from -180°C at night to 430°C during the day due to its lack of atmosphere.

NO ATMOSPHERE – Mercury has an extremely thin atmosphere, primarily composed of oxygen, sodium, hydrogen, helium, and potassium, making it almost a vacuum.

MERCURY’S ORBIT – The elliptical path that Mercury takes around the Sun, completing one revolution in about 88 Earth days.
