2 days ago · 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.
2 days ago · Mercury is the only metal for which the alchemical planetary name survives, as it was decided it was preferable to "quicksilver" as a chemical name. History. Mercury was found in Egyptian tombs that date from 1500 BC; cinnabar, the most common natural source of mercury, has been in use since the Neolithic Age.
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.

Jun 3, 2024 · With a radius of about 2,440 km (1,516 miles), Mercury is the smallest major planet, smaller even than Jupiter’s largest moon, Ganymede, or Saturn’s largest moon, Titan. In addition, Mercury is unusually dense. Although its mean density is roughly that of Earth’s, it has less mass and so is less compressed by its own
3 days ago · A solar day — the amount of time it takes the Sun to rise, set and rise to the same place again — on Mercury lasts about 176 Earth days. And here is another weird fact about Mercury: one year on this planet is twice shorter than a single day and takes 88 Earth days.
