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—the smallest planet in our solar system and nearest to the Sun—is only slightly larger than Earth's Moon. Its surface is covered in tens of thousands of impact craters. From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as 11 times ...
Jun 3, 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.
Mercury is the second densest planet, after Earth. It has a large metallic core with a radius of about 1,289 miles (2,074 kilometers), about 85% of the planet's radius. There is evidence that it is partly molten or liquid.
Mercury is the smallest planet in the Solar System. One of five planets visible with the naked eye a, Mercury is just 4,879 Kilometres across its equator, compared with 12,742 Kilometres for the Earth. Mercury is the second densest planet. Even though the planet is small, Mercury is very dense.
Jun 13, 2024 · Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. It has a solid surface that is covered with craters. Instead of an atmosphere, Mercury possesses a thin exosphere made up of atoms blasted off the surface by the solar wind and striking meteoroids.
Oct 19, 2018 · Living up to its name, Mercury is the fastest planet in the solar system, speeding along at about 29 miles per second and completing each orbit around the sun in just 88 Earth days. Mercury...
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.
Jun 9, 2023 · Mercury is the closest planet to the sun and also the smallest planet in the solar system. The small and cratered planet does not have any moons and zips around the sun faster than any...
