Mercury is the smallest and closest to the Sun of the eight planets in the Solar System , [a] with an orbital period of about 88 Earth days. Seen from the Earth, it appears to move around its orbit in about 116 days, which is much faster than any other planet. This rapid motion may have led to it being named after the Roman deity Mercury , the fast-flying messenger to the gods. Because it has almost no atmosphere to retain heat, Mercury's surface experiences the greatest temperature variation of all the planets, ranging from 100 K (−173 °C; −280 °F) at night to 700 K (427 °C; 800 °F) during the day at some equatorial regions. The poles are constantly below 180 K (−93 °C; −136 °F). Mercury's axis has the smallest tilt of any of the Solar System's planets (about 1 ⁄ 30 of a degree), but it has the largest orbital eccentricity . [a] At aphelion , Mercury is about 1.5 times as far from the Sun as it is at perihelion . Mercury's surface is heavily cratered and similar in appearance to the Moon , indicating that it has been geologically inactive for billions of years. |

Mercury is the innermost planet in the Solar System . It is also the smallest, and its orbit is the most eccentric (that is, the least perfectly circular) of the eight planets. [a] It orbits the Sun once in about 88 Earth days, completing three rotations about its axis for every two orbits. The planet is named after the Roman god Mercury , the messenger to the gods. |

Mercury is the innermost and smallest planet in the Solar System , [a] 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. The perihelion of Mercury's orbit precesses around the Sun at an excess of 43 arcseconds per century, a phenomenon that was explained in the 20th century by Albert Einstein 's General Theory of Relativity . [11] 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. |

Mercury ( Template:PronEng ) is the innermost and smallest planet in the solar system , orbiting the Sun once every 88 days. It ranges in brightness from about −2.0 to 5.5 in apparent magnitude , but is not easily seen as its greatest angular separation from the Sun (greatest elongation ) is only 28.3°. It can only be seen in morning or evening twilight . Comparatively little is known about the planet: the only spacecraft to approach Mercury was Mariner 10 from 1974 to 1975, which mapped only 40%–45% of the planet’s surface. |

This mosaic of Mercury was taken by the Mariner 10 spacecraft during its approach on 29 March 1974. The mosaic consists of 18 images taken at 42 s intervals during a 13 minute period when the spacecraft was 200,000 km (about 6 hours prior to closest approach) from the planet. click here for full-sized image |

Mercury is the closest planet to the Sun . It has no satellites and only trace amounts of hydrogen and helium in its atmosphere (temporarily captured from the Solar wind ). Its surface appears very similar to Earth 's Moon , but the planet has a much larger iron core and is therefore much denser. Its most distinctive known surface feature is Caloris Basin, a colossal impact crater approximately 1350 km in diameter. |
