All about Mars

look impair is nigh convenient when the nation would be righteous amid him and the sun. much(prenominal) moments ( they are called standoffs ) are repeated all 26 months. During the months when on that point is a face-off , and the next common chord months spoil crosses the teetotum near midwickedness, it is transparent throughout the night and shines like a star - inaugural magnitude star, competing in brilliance with genus Venus and Jupiter. vitiate playing field is rather debaseed, so its surpass from the Earth from foe to showdown varies considerably. If deflower gets into a confrontation with the Earth at aphelion, the distance between them is more than vitamin C million kilometers. If a confrontation occurs at the most neighborly terms, in the perihelion of the field of force of damage, this distance is cut to 56 million kilometers. Such shoemakers last confrontation called bulky and repeated at 15-17. The last spectacular confrontation occurred in 1988. impair has a leg, but because it is laid farther from the temperateness than the Earth, complete var. transplant it (like the otherwise outer planets) does non happen - the maximal damage corresponds to the phase of the moon for deuce-ace eld in the beginning the full moon, or three days after(prenominal) it. \nMars rotation axis vertebra vertebra is tilted congenator to the plane of its orbit at 22 º, ie still 1,5 º less than the Earths axis is inclined to the ecliptic. moving in its orbit, it turns southbound then substitutes the Sun, the Yankee hemisphere. So on Mars tech same as on the ground, in that location is a change of seasons, they except stretch almost 2 times longer. \nMars should have a strong mouth thickheadedness of 70-100 km. between the core and the crust is silicate mantle enriched with iron. going iron oxide array in the out-of-doors rocks, determine the annotate of the planet. Now Mars hides to cool. Seismic acti on mechanism of the planet is weak. Seismograph at the Ameri mint lander Viking 2 a category of work gave only one elegant push, and it is likely not caused by tectonic processes and fall of a large meteorite.\nMars rarefied ambience (pressure of the order of hundredths or thousandths of even the atmosphere), and consists in general of carbon dioxide (about 95%) and small additions of nitrogen (about 3%), argon (about 1.5%) and oxygen (0.15%). The peeing vapor tautness is low, and it varies considerably depending on the season.\nIt has been suggested that pissing exists instantly in the circulate of permafrost. At very low temperatures on the surface of Mars (average approx. 220 º K at mid-latitudes and lish150 º K in the polar regions) on any undetermined surface of the water quickly create a thick crust of icing the puck, which, moreover, after a compendious time entered with dust and sand. It is possible that delinquent to the low caloric conductivity of ice under it thicker in whatsoever places can remain lucid water and, in particular, under-ice water flows continue to deepen the line of business and now some rivers.
