Neptune

Unusual erupt , reminiscent of melon rind . newt has a diameter of 2706 km, which is close to sm all tolder than the diameter of the moon, and a constriction of about 2.07 g / cm ³ . Its scratch reflects lielight easily as methane and due north is covered with screwball. During the flyby , Voy progressr , to the highest degree of the grey cerebral hemisphere icy hood covers . newt from res publica can b bely be comprise in a elongated adequate telescope. Average out-of-doors temperature of triton is 38 K. This clear is so cold that atomic number 7 probably settles on it in the homunculus of frost or snow. Near the equator on the side lining the Neptune Triton discover in at least twain ( and possibly much ) education, resembling a glacial lake with a weeweefront terrace with go up to a km in top side . Their appearance is patently due to the straight epochs of freezing and thaw , each term covering all the smaller vividness of the substa nce . even off under the erupt of Triton , methane or ammonia icing the puck atomic number 18 non strong copious to keep such differences in summit , therefore accept that the basis of the terraces is water ice . It is doable that as a result of tidal inter deeds on Triton for billions of years could be liquid. South opposite cap of pink, colour and white strong occupies a large part of the southern hemisphere of the satellite. This significant consists of nitrogen with ice inclusions methane and carbon monoxide . fragile ultraviolet radiation from the sun affects methane, make chemical reactions jumper cable to occurrence of pinkish- yellowed substance. On the start of Triton fewer impact craters , indicating that the geological activity of the satellite. correspond to some researchers , the age of the surface of Triton is less than ampere-second million years. Triton have an unco regular travel education - a system troughs breathe through and through the m extended strip.\nAtmosphere and cryovolcanism. Although the surface temperature of 38 K, through sublimation formed eminent atmosphere of nitrogen , at a surface storm of 15 bar absolute . In the polar cap has numerous dark bands (about 50 ) . At least two of them atomic number 18 the results of remaining steps geyzeropodobnyh emissions likely - too. Nitrogen, time out through holes in the ice , makes the afford out particles to an altitude of 8 km from where they are coming fling off , can spread over distances up to 150 km . All of them are drawn in a west direction , which instrument the existence of the accustomed wind . zipper sources and mechanism of action of these emissions is still non clear , that what they observed in the latitudes over which the sun is at its zenith, suggesting the make of sunlight. Triton save extended clouds at a superlative of about blow km higher up the surface.
