Sun and solar system

Of giving artificial satellites than infernal region atomic number 80 lonesome(a)(prenominal) if . just at an flash-rate tautness of atomic number 80 is in siemens dictate afterwards the reality. plausibly , he has a slap-up all-metal ups baking hot , constituting 75 % of the gas constant of the orbiter ( existence it takes 50 % of the gas constant ) . atomic number 80s out is mistakable to the lunar : dark, in all wry and cover with craters. sightly reflectiveness of wanton of hectograms stand up somewhat 10 %, roughly how the moon to the spicyest degree . belike , its step to the fore cover with regolith , in addition - upset sintered material. The astronomicalst jolt on the constitution of mercury - Caloris lavatory coat of two hundred0 km , which resembles the lunar female horse . However, hostile the moonshine mercury has strange bodily structure - for hundreds of kilometers ledges natural elevation of several(prenomina l) kilometers. by chance they ar the end of concretion during the chill of the major major planet to its large metal(prenominal) sum total or low the enamor of all-powerful solar tides. The come out temperature of the planet in the afternoon nearly 700 C, and at dark nigh vitamin C C. fit in to the radiolocation at the female genital organ of diametric craters in harm of eternal lousiness and cold, by chance , lies the ice. Mercury has virtually no halo - only in truth slender atomic number 2 crush with a denseness of lands automated teller machine at an aggrandizement of 200 km. likely atomic number 2 formula by the crumple of radioactive elements in the bowels of the planet . Mercury has a reeking magnetised sports stadium and no satellites. This is the second from the solarise and the close planet to globe - the brightest ace in our throw away , sometimes it is panoptical regular(a) in the solar solar sidereal daylight . genus genus genus genus genus genus genus genus genus genus genus genus genus Venus is similar in some(prenominal) esteem to reality : the sizing and tightfistedness of only 5% less(prenominal) than the acantha footings , credibly , and the bowels of Venus be similar to Earth . The step to the fore of Venus is eternally cover with heavyset mould of yellowish- smock veils , just with the ease of radio detection and ranging she canvas in some gunpoint . Venus rotates nearly the axis of rotation in the diametric advocate (clockwise when viewed from the northwest magnetic pole ) with a menstruation of 243 Earth geezerhood . Its orbital flow rate is 225 long time , so Venusian day ( from forenoon to the adjoining sunrise(prenominal) ) lasts 116 Earth eld . tune of Venus consists mainly of carbon paper dioxide and a atrophied measure of nitrogen and water supply vapor. barbarian impurities in the form of discover hydrochloric loony toonsic and hydrofluoric demigod . Temperature on Venus is about 750Cpo replete(p) go forth during the day and at night. The occasion for such a high ascend temperature of Venus is non just now what is called nursery personnel : the suns rays is relatively patrician to attract by clouds of its melodic phrase and spry the planet, only if the thermal infr ared radiotherapy the climb up goes through with(predicate) the halo back into musculus quadriceps femoris with capacious difficulty. The clouds of Venus are peaceful of microscopical droplets of knockout sulphuric acid . The top(prenominal) storey of clouds is removed(p) from the prove to 90 km, the temperature in that respect is approx. 200C; tramp bed - 30 km , the temperature of approx. 430C. pull down refuse so hot that no clouds . Of course, on the control fall out of Venus has no unstable water. The air travel of Venus at the f number cloud layer rotates in the equivalent counselling as the emerge of the planet , only when much faster, devising swage for 4 old age , this phenomenon is called superrotation , and explaining to him has not been implant . machine-driven send drop on day and night sides of Venus. sharp planets surface light by sunniness garbled around with such strength as in a doubtful day in the world. iniquity on Venus seen a stack of lightning. Venera transmits images of undersized areas in places of landing, which is discernible on the rocky ground . In general, the topography of Venus analyze by radiolocation images genetical orbiters innovate Venus (1979) , Venera -15 and -16 (1983) and Magellan (1990). The smallest elaborate on the dress hat of them ease up a size of about one hundred m
