Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius ( Mercury ), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars.
Mercury is the smallest planet in our solar system and the nearest to the Sun. Mercury is only slightly larger than Earth's Moon. Its surface is covered in tens of thousands of impact craters.
Jul 20, 2024 · Mercury, the innermost planet of the solar system and the eighth in size and mass. Its closeness to the Sun and its smallness make it the most elusive of the planets visible to the unaided eye. Because its rising or setting is always within about two hours of the Sun’s, it is never observable when the sky is fully dark.
Introduction Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C).
Mercury is the smallest planet in our solar system. It’s just a little bigger than Earth’s Moon. Mercury itself, though, doesn’t have any moons. It is the closest planet to the Sun, but it’s actually not the hottest. Venus is hotter. Along with Venus, Earth, and Mars, Mercury is one of the rocky planets.

Highlights. Mercury, the closest planet to the Sun, has surface temperatures of up to 465 ° C (869 ° F), but Venus is hotter. Like our Moon, Mercury has water ice in permanently shadowed craters at the poles. Mercury has a particularly large core and scientists aren't sure why.
Mercury is the closest planet to the Sun, and the smallest planet in the solar system. It has a large iron core that accounts for about three-quarters of its mass. By contrast, Earth ’s iron core accounts for only one-third of its mass. Compare the sizes and order of the planets. A rocky outer shell surrounds the planet’s core.
