The planet Mars has characteristics similar to Earth. Both have the same amount of land surface, supported by poles. In fact, both these planets have the same slope at its rotational axis.
Although it has similarities, planet Earth has a difference with Mars. Differences include atmospheric pressure and surface temperature on Mars is smaller than Earth. For long days, Mars is similar to Earth, 24 hours 37 minutes and the long years of Mars tend to be longer, which is 687 days.
The big difference between the Earth and Mars shows that the gravity on Mars 62 percent lower than the Earth. Differ only 0.38 of a standard Earth. People who weighs 100kg on Earth, on Mars weighs only 38 kg.
Cause there is a difference of gravity is caused by several factors, such as mass, density, and the radius of the main cause. Although Mars has a surface area of land which is almost equal to the Earth, but Mars is actually only have half the diameter and density of less than Earth.
The researchers accounted for the large amount of gravity using Newton's gravitational theory which states that the force of gravity is given by an object is proportional to its mass. When applied to the spherical body such as a planet with a certain mass, surface gravity would be inversely proportional to the square of the radius.
