[88], Mercury is too small and hot for its gravity to retain any significant atmosphere over long periods of time; it does have a tenuous surface-bounded exosphere[90] containing hydrogen, helium, oxygen, sodium, calcium, potassium and others[15][16] at a surface pressure of less than approximately 0.5nPa (0.005 picobars). Planet Mercury Facts. If you enter a single word, we'll find words that allierate with it. mercury planet woman. Although Mercury is farthest from Earth when it is full, the greater illuminated area that is visible and the opposition brightness surge more than compensates for the distance. [106][107] This dynamo effect would result from the circulation of the planet's iron-rich liquid core. [161], In medieval Islamic astronomy, the Andalusian astronomer Ab Ishq Ibrhm al-Zarql in the 11th century described the deferent of Mercury's geocentric orbit as being oval, like an egg or a pignon, although this insight did not influence his astronomical theory or his astronomical calculations. It was associated with the direction north and the phase of water in the Five Phases system of metaphysics. 3. A word or sentence you would like to alliterate. 5. [31] Essentially because Mercury is closest to the Sun, when taking an average over time, Mercury is most often the closest planet to the Earth,[17][18] andin that measureit is the closest planet to each of the other planets in the Solar System. [143][144] At greatest western elongation, Mercury rises at its earliest before sunrise, and at greatest eastern elongation, it sets at its latest after sunset. b) All rotate in the same direction. These twisted magnetic flux tubes, technically known as flux transfer events, form open windows in the planet's magnetic shield through which the solar wind may enter and directly impact Mercury's surface via magnetic reconnection[109] This also occurs in Earth's magnetic field. The diameter of Planet Mercury is 4,878 km (3,031 miles).. 5. It is unlikely that any living beings can withstand those conditions. This reference page can help answer the question what are some adjectives commonly used for describing PLANETS. They provided the first views that resolved surface features on the parts of Mercury that were not imaged in the Mariner 10 mission. Planets adjectives are listed in this post. [125] The two hottest places on the equator are therefore at longitudes 0W and 180W, and the coolest points on the equator are at longitudes 90W and 270W. However, the MESSENGER project uses an east-positive convention. (See List of constellations.) The Babylonians called the planet Nabu after the messenger to the gods in their mythology. 5 Vatican city is the smallest country in the world. Thus, to a hypothetical observer on Mercury, the Sun appears to move in a retrograde direction. The planet is rendered invisible from Earth on both of these occasions because of its being obscured by the Sun,[139] except its new phase during a transit. Every other planet has something cool about them except this loser. The adjective from the planet Mercury is Mercurian (capitalized as derived from a proper noun), for example: The Mercurian craters look spectacular. Four Earth days after perihelion, the Sun's normal apparent motion resumes. It has a thin atmosphere, and it doesnt have any moons. terrestrial planets: Mercury, Venus, Earth, Mars. The "4" is a reference number in the SumeroAkkadian transliteration system to designate which of several syllables a certain cuneiform sign is most likely designating. This dude is literally so useless. It has a large metallic core with a radius of about 1,289 miles (2,074 kilometers), about 85 percent of the planet's radius. (Roman god) The Roman god associated with speed, sometimes used as a messenger. [141] The opposite is true for Venus, which appears brightest when it is a crescent, because it is much closer to Earth than when gibbous. This contributes to the space weathering of the planet's surface. It has a surface boundary exosphere instead of a layered atmosphere, extreme temperatures, and high solar radiation. At an average distance of 36 million miles, Mercury is the closest planet to our Sun. red entire giant distant larger brighter extrasolar strange terrestrial minor alien rocky unknown outer tenth sized close amazing dead interior healthy habitable major primary native malignant remotest nearby certain fictional upper hotter inner actual nearer desolate human vile devastated vivid active plundered peaceful invisible beautiful chief 11. [81], According to NASA, Mercury is not a suitable planet for Earth-like life. In other words, the orbits of the two planets approach each other most closely. Mercury, the innermost planet of the solar system and the eighth in size and mass. mercurial adjective /mkjril/ /mrkjril/ (literary) often changing or reacting in a way that is unexpected synonym volatile Emily's mercurial temperament made her difficult to live with. Rare forms, or forms only attested with spellings not in keeping with the IAU-approved spelling (such as c for k), are shown in italics. Its a little bigger than Earths Moon. Moon Like Terra, Luna, the Roman name for the Moon, seems to appear only in science fiction these days. Venus is hotter. It has a mass of about 3.285 10^23 kg or about 5.5% that of Earth. If Mercury were tidally locked, its dark face would be extremely cold, but measurements of radio emission revealed that it was much hotter than expected. elemental, fulminating, high, inorganic less, liquid, little, metal metallic, more, much, new organic, pressure, pure, red total, toxic, winged Hope this word list had the adjective used with mercury you were looking for. But in some cases Mercury can better be observed in daylight with a telescope when the position is known because it is higher in the sky and less atmospheric effects affect the view of the planet. Moore Boeck. [98], On November 29, 2012, NASA confirmed that images from MESSENGER had detected that craters at the north pole contained water ice. However, with noticeable eccentricity, like that of Mercury's orbit, the tidal force has a maximum at perihelion and therefore stabilizes resonances, like 3:2, ensuring that the planet points its axis of least inertia roughly at the Sun when passing through perihelion. 3 Russia is the largest country in the world. Mercury is the inner most planet in our solar system. A new paper details how the hydrological cycle of the now-dry lake at Jezero Crater is more complicated than originally thought. Forming Adjectives with the Planets. Earth? These were Mercury, Venus, Mars, Jupiter and Saturn. Language: English. . Mercury can be observed for only a brief period during either morning or evening twilight.[139]. "First planet" redirects here. In Hindu astrology, the planet Mercury is considered to be a factor of intelligence, logic and friendship. It is a heavy, opaque, glistening liquid (commonly called . [98], During its second flyby of the planet on October 6, 2008, MESSENGER discovered that Mercury's magnetic field can be extremely "leaky". Satellites from NASA and its partners help collect that data. The element is unique in being a metal that is liquid at room temperature; it is thus anomalous. [183] Most of the planet has been mapped by the Arecibo radar telescope, with 5km (3.1mi) resolution, including polar deposits in shadowed craters of what may be water ice.[184]. Mercury (Planet) Impact Crater. Mercury is designated by the symbol . i / the planet nearest in distance to the sun (Definition of mercury from the Cambridge Academic Content Dictionary Cambridge University Press) Examples of mercury mercury Phil Davis However, accurate modeling based on a realistic model of tidal response has demonstrated that Mercury was captured into the 3:2 spin-orbit state at a very early stage of its history, within 20 (more likely, 10) million years after its formation. [145] In both of these cases, the angle at which the planet's orbit intersects the horizon is maximized, allowing it to rise several hours before sunrise in the former instance and not set until several hours after sundown in the latter from southern mid-latitudes, such as Argentina and South Africa.[145]. Like its fellow terrestrial planets, Mercury has a central core, a rocky mantle, and a solid crust. Mercury can come as near as 82,200,000 kilometres (0.549 astronomical units; 51.1million miles) to Earth, and that is slowly declining: The next approach to within 82,100,000km (51.0million miles) is in 2679, and to within 82,000,000km (51million miles) in 4487, but it will not be closer to Earth than 80,000,000km (50million miles) until 28,622. [14] The mean apparent magnitude is 0.23 while the standard deviation of 1.78 is the largest of any planet. [97] Studies indicate that, at times, sodium emissions are localized at points that correspond to the planet's magnetic poles. Orbit The orbit of Mercury is the most eccentric of the planets in the solar system. Mercury and Venus occult each other every few centuries, and the event of May 28, 1737 is the only one historically observed, having been seen by John Bevis at the Royal Greenwich Observatory. He was 58 years old. Structure. It made a fly-by of Earth in August 2005, and of Venus in October 2006 and June 2007 to place it onto the correct trajectory to reach an orbit around Mercury. This answer is: MESSENGER's principal investigator Sean Solomon is quoted in The New York Times estimating the volume of the ice to be large enough to "encase Washington, D.C., in a frozen block two and a half miles deep". Attested adjectival forms of the larger bodies are listed below, along with the two small Martian moons; in some cases they are accompanied by their demonymic equivalents, which denote hypothetical inhabitants of these bodies. the transit of the planet mercury in front of the sun on november 11, 2019, from france - planet mercury stock pictures, royalty-free photos & images sketch illustration - solar system with sun and all planets - planet mercury stock illustrations As a result, only three space probes have visited it so far. Due to Mercury's 3:2 spin-orbit resonance, a solar day lasts about 176 Earth days. [98] Unlike Earth's, Mercury's poles are nearly aligned with the planet's spin axis. A Grammar-based themed worksheet aimed at practising the comparative and superlative in English. Tells what kind, which one, how many, or how much. [162][163] In the 12th century, Ibn Bajjah observed "two planets as black spots on the face of the Sun", which was later suggested as the transit of Mercury and/or Venus by the Maragha astronomer Qotb al-Din Shirazi in the 13th century. Mercury is the fastest planet in our solar system traveling through space at nearly 29 miles (47 kilometers) per second. [132][133], In 1859, the French mathematician and astronomer Urbain Le Verrier reported that the slow precession of Mercury's orbit around the Sun could not be completely explained by Newtonian mechanics and perturbations by the known planets. [188] A proposed alternative approach would use a solar sail to attain a Mercury-synchronous orbit around the Sun. The eccentricity of Mercury's orbit makes this resonance stableat perihelion, when the solar tide is strongest, the Sun is nearly still in Mercury's sky. In addition to continued observations and mapping of Mercury, MESSENGER observed the 2012 solar maximum. Supply your ELL classroom with this worksheet exploring synonyms and antonyms for popular adjectives. Fill in the blanks with the correct form of adjectives describing the planets 1. [156][157][158] Hindu mythology used the name Budha for Mercury, and this god was thought to preside over Wednesday. A teacher walks into the Classroom and says If only Yesterday was Tomorrow Today would have been a Saturday Which Day did the Teacher make this Statement? A new study finds the speed of sound is slower on Mars and that, mostly, a deep silence prevails. Mercury is the fastest planet in our solar system - traveling through space at nearly 29 miles (47 kilometers) per second. Almond = A remnant of "home" and safe returns from travel. For many years after the Mariner 10 encounters, the origin of Mercury's magnetic field remained the subject of several competing theories. Fact 2. [149], Because the shift of 0.15 revolutions in a year makes up a seven-year cycle (0.15 7 1.0), in the seventh year Mercury follows almost exactly (earlier by 7 days) the sequence of phenomena it showed seven years before.
