Deimos

Last crawled date: 4 years, 3 months ago

Deimos is probably an asteroid whose orbit was disturbed by the Jupiter gravity so that it was captured by Mars although this theory still is under certain controversy. Like most of the bodies of comparable size, Deimos has a very irregular form, and measures 15x12x10 km Deimos is made up of rich carbon rock very similar to asteroids of type C (condrita carbonácea , and of ice It has craters but its surface is remarkably smoother than the one of Fobos, due to the partial filling of its craters with regolito Sight from Deimos, Mars would be 1000 times greater and 400 times more shining than the Full Moon Vista from the Earth occupying 1/11 of the width of a celestial hemisphere. Sight from Mars Deimos has nongreater an angular diameter of 2.5 ', so that at first it appears as a star. At his moment of more brightness ('Full Moon') it is seen more or less equal of brilliant that Venus from the Earth In first quarter or decline he would be as shining as Vega. Nevertheless, the orbital period of Deimos (approximately 30.5 hours) exceeds the Martian solar day (24.5 hours) by so just a short time that they spend 2.7 days from the exit to the putting, for an equatorial observer. #Ayrk #Deimos #Mars #Moon
