Characteristics of the planet Mars

 Mars is the fourth planet of the Solar System. Form leaves from denominated telluric planets (of rocky nature, as the Earth) and is first of outer planets tothe Earth orbit. He is, possibly, most similar to the Earth.
        Tycho Brahe measured with high accuracy the Mars movement in the sky. The data on the retirement pretend (bows) allowed Kepler tofind the elliptical nature of their orbit and to determine the laws del planetary movement known like laws Kepler.
            The superior or outer planets, never happen between the Sun and the Earthneither never is seen them in flood nor in quarter; their phases are little noticeable, fact that is easy to demonstrate geometrically. Considering the Sun-Earth-Mars triangle, the phase angle is theone that forms the seen Sun and the Earth from Mars. It reaches his maximum value in the quadratures when triangle STM is Earth rectangle. For Mars, this angle of phase is never greater of 42º, andits hunchbacked disc aspect is analogous to which it presents/displays the Moon 3.5 days before or after the Full Moon. This phase, visible with a fan telescope, did not manage to be Vista by Galileothat only supposed its existence.
            Mars was the Roman God of the war and his equivalent Greek was called you plow. The red color of the Mars planet, related to the blood, favored that it wasconsidered him from old like a symbol of the God of the war. Sometimes reference to Mars like the Red Planet is made.
            Of the duration of the sidereal day it is deduced easily that thesolar day h 39 lasts in Mars of 24 min 35.3 s. The solar day half or time between two consecutive steps of the average Sun by the meridian of the place, 41 lasts 24 h min 18.6 s. a Martian day bond,therefore, 1.029 days terrestrial. The solar day in Mars has, like in the Earth a variable duration, which must that the planets follow elliptical orbits around the Sun that are not crossed with...
