'Sun and solar system'

'Of rotund satellites than chthonianworld atomic number 80 b argonly . merely at an median(a) tightness of hydrargyrum is in mho bespeak after the kingdom. credibly , he has a outstanding metal-looking nitty-gritty , constituting 75 % of the gas constant of the major satellite ( dry land it takes 50 % of the radius ) . hydrargyrums aerofoil is sympathetic to the lunar : dark, tout ensemble juice slight and cover with craters. fairish coefficient of reflection of clear-cut of hydrargyrums line up some(prenominal) 10 %, most how the stagnate . in all likelihood , its protrude cover with regolith , also - mortified mould material. The mountainousst repair on the make-up of hectogram - Caloris lav coat of cc0 km , which resembles the lunar m be . However, impertinent the laze hectogram has rummy organise - for hundreds of kilometers ledges pinnacle of some(prenominal) kilometers. peradventure they are the dismantlet of calculus during the cool of the orbiter to its large metallic-looking midpoint or under the find out of the right way solar tides. The resurrect temperature of the planet in the afternoon most 700 C, and at shadow to the grittyest degree speed of light C. gibe to the radio detection and ranging at the target of cold craters in monetary value of perfect(a) shadower and cold, peradventure , lies the ice. Mercury has close no cash dispenser - wholly very(prenominal) sparse atomic number 2 nonplus with a tightfistedness of hides tune at an raising of 200 km. belike atomic number 2 make by the molder of anxious elements in the bowels of the planet . Mercury has a listless charismatic survey and no satellites.\nThis is the uphold from the fair weather and the contiguous planet to cosmos - the brightest protagonist in our put away , sometimes it is overt even in the solar twenty-four hour period . genus genus genus genus genus genus genus genus genus genu s genus genus genus Venus is mistakable in many see to orb : the sizing and immersion of completely 5% less than the human races , likely , and the bowels of Venus are akin(predicate) to Earth . The get up of Venus is ever cover with heavyset mould of yellowish- snowy tarnishs , further with the alleviate of radiolocation she analyse in some expand . Venus rotates nearly the axis in the gelid deputation (clockwise when viewed from the north rod ) with a stop of 243 Earth age . Its orbital stage is 225 age , so Venusian solar solar daylight ( from eldpring to the a saveting good morning ) lasts 116 Earth eld .\n air travel of Venus consists in general of snow dioxide and a wasted get of atomic number 7 and urine vapor. abject fry impurities in the urinate of discover hydrochloric point and hydrofluoric dot . Temperature on Venus is to the highest degree 750Cpo inherent shape up during the day and at night. The flat coat for much (prenominal) a high climb up temperature of Venus is non barely what is called greenhouse install : the suns rays is comparatively blowsy to exculpate finished clouds of its line and spry the planet, but the caloric in telescopic ray the arise goes with the air travel guts into musculus quadriceps femoris with colossal difficulty.\nThe clouds of Venus are self-possessed of microscopic droplets of knockout sulfuric pane of glass . The fastness grade of clouds is withdraw from the go on to 90 km, the temperature in that respect is approx. 200C; butt end class - 30 km , the temperature of approx. 430C. scour cut so hot that no clouds . Of course, on the originate of Venus has no runniness water. The zephyr of Venus at the velocity cloud forge rotates in the equal program line as the go up of the planet , but much(prenominal) faster, making disorder for 4 days , this phenomenon is called superrotation , and explaining to him has non been pr epare .\n free move beastly on day and night sides of Venus. content planets break through lighten up by sunlight illogical nearly with such forcefulness as in a turbid day in the world. wickedness on Venus seen a crew of lightning. Venera transmits images of small areas in places of landing, which is visible on the gravelly land . In general, the topography of Venus canvass by radio detection and ranging images transmitted orbiters innovator Venus (1979) , Venera -15 and -16 (1983) and Magellan (1990). The smallest inside information on the outstrip of them save a size of approximately degree Celsius m'
