         TEMPERATURE

Mars is farther from the sun than the earth,so,as you would expect,the temperature of mars is colder.For the most part it is very cold on Mars.The only exception is during the summer days close to or at the equator.Even at the equator,the night time temperatures tall well below zero.
   PHYSICAL CHARACTERISTICS 

Mars is aproximately half the diameter of Earth with a surface area only slightly less than the total area of earth's dry land.Mars is less dense than earth ,having about 15% of earth's volume and 11% of earth's mass,resulting in about 38% of Earth's surface gravity.
