Mercury

__ MERCURY﻿ __

Mercury is the 1st planet in our solar system and it is also one of the smallest. Scientists believe that this planet has no human life becuase there is no water or air and the radient heat is way to high at day and suprisenly to cold at night. It's average temperature is 350 degrees at day, and at night it is minus 170 degrees this is why we cant live there. A Mercury year is 87.696 of our days and a Mercury day is 58.646 of our days!!!! Mercury is a massive metal ball coverd with rocky crust. Its core(the middle) is made of nickle and iron and the out side is made of mantle. Scientists think part of the core is liquid. The planet Murcury has no atmosphere and no Moons. This is becuase it is close to the Sun. The Sun is so huge(massive) that the strong gravatation that it would suck the Moon away in a second. Mercury is visible to the naked eye but it is only visible in the twilight hours (night). Mercury is 60% smaller than earth, Mercury is the solar systems scrauniest planet. It is much too small to generate the strong gravatational feild needed to retain an atmosphere. Mercury is filled with massive craters!!! This is where objects,like meteors, have smashed into it. Stuff like this has crashed into all the planets just as much....but we dont see as many on Mercury. This is because things like water,wind and general stuff that goes along with having an atmosphere smooths the craters out for awhile. So, with no atmosphere, we get to see everything that has ever crashed into Mercury. Mercury is different to Earth because, well many reasons really. The size difference, the rocks, the atmosphere. So many reasons make Earth and Mercury different.
