Mercury is one of four terrestrial planets in the Solar System, which means it is a rocky body like Earth. It is the smallest planet in the Solar System, with an equatorial radius of 2,439.7 kilometres (1,516.0 mi). Mercury is also smaller—albeit more massive—than the largest natural satellites in the Solar System, Ganymede and Titan.
Mercury (element) rhombohedral ( hR1) Mercury is a chemical element; it has symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( / haɪˈdrɑːrdʒərəm / hy-DRAR-jər-əm) from the Greek words hydor (water) and argyros (silver). [8]
Jul 1, 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.
But Mercury is the fastest planet, zipping around the Sun every 88 Earth days. Mercury is appropriately named for the swiftest of the ancient Roman gods. Eyes on the Solar System lets you explore the planets, their moons, asteroids, comets and the spacecraft exploring them from 1950 to 2050.

Jun 13, 2024 · Mercury is a terrestrial planet. It is small and rocky. Mercury has a thin exosphere. Mercury’s surface can be as hot as 800 degrees F during the daytime and as cold as -300 degrees F during the nighttime. (But Mercury is not the hottest planet in the solar system. The hottest planet is Venus.) Mercury’s poles have water-ice. Time on Mercury
Jun 9, 2023 · Mercury is the smallest planet in the solar system — it is only slightly larger than Earth's moon. Since it has no significant atmosphere to stop impacts, the planet is pockmarked with craters.
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.
