Encyclopedia

Mercury is the innermost and smallest planet in the Solar System, orbiting the Sun once every 87.969 Earth days. The orbit of Mercury has the highest eccentricity of all the Solar System planets, and it has the smallest axial tilt. It completes three rotations about its axis for every two orbits. Mercury is bright when viewed from Earth, ranging from −2.3 to 5.7 in apparent magnitude, but is not easily seen as its greatest angular separation from the Sun is only 28.3°. Since Mercury is normally lost in the glare of the Sun, unless there is a solar eclipse it can be viewed from Earth’s Northern Hemisphere only in morning or evening twilight, while its extreme elongations occur in declinations south of the celestial equator, such that it can be seen at favorable apparitions from moderate latitudes in the Southern Hemisphere in a fully dark sky. — Wikipedia

  • The true power of the solar wind
    on June 12, 2018 at 2:57 pm

    The planets and moons of our solar system are continuously being bombarded by particles from the sun. On the Moon or on Mercury, the uppermost layer of rock is gradually eroded by the impact of sun particles. New results show that previous models of this process are incomplete. The effects of solar wind bombardment are much more drastic than previously thought. […]

  • Mercury's thin, dense crust
    on April 27, 2018 at 2:03 pm

    A planetary scientist has used careful mathematical calculations to determine the density of Mercury's crust, which is thinner than anyone thought. […]

  • Meteorite diamonds tell of a lost planet
    on April 18, 2018 at 6:48 pm

    Scientists have examined a slice from a meteorite that contains large diamonds formed at high pressure. The study shows that the parent body from which the meteorite came was a planetary embryo of a size between Mercury and Mars. […]

  • Understanding Mercury's magnetic tail
    on April 17, 2018 at 3:57 pm

    Theoretical physicists used simulations to explain the unusual readings collected in 2009 by the Mercury Surface, Space Environment, Geochemistry, and Ranging mission. The origin of energetic electrons detected in Mercury's magnetic tail has puzzled scientists. This new study provides a possible solution to how these energetic electrons form. […]

  • Arctic permafrost might contain 'sleeping giant'...
    on December 12, 2018 at 1:27 pm

    As temperatures rise in the Arctic, permafrost, or frozen ground, is thawing. As it does, greenhouse gases trapped within it are being released into the atmosphere in the form of carbon dioxide and methane, leading to previously underestimated problems with ocean acidification and potential mercury poisoning. […]

  • BepiColombo now firing on all cylinders
    on December 5, 2018 at 3:30 pm

    BepiColombo, the joint ESA/JAXA spacecraft on a mission to Mercury, is now firing its thrusters for the first time in flight. […]

  • Scientists consider climate change-resistant crops
    on December 5, 2018 at 2:31 pm

    When it gets hot outside, humans and animals have the luxury of seeking shelter in the shade or cool, air-conditioned buildings. But plants are stuck. […]
