Mars is 0.107 times the mass of earth. The reciprocal of that is the number of planets the mass of Mars it would take to equal a planet the mass of earth, or a little over 9 and 1/3.
Mars is a little over half the size of Earth.
It is difficult to quantify how many Mars planets equal one Earth due to the vast differences in size and composition between the two planets. However, it is estimated that it would take around 6.5 Mars planets to equal the mass of Earth.
None, because only half an Earth can fit inside of Mars.
One year on Mars is equivalent to about 687 Earth days.
Mars would have to find more mass if it wanted to equal the Earth's. It has only 11% of Earth's mass.
About an estimate of 2600600 mars' would fit into the Sun.
The pressure in Earth's atmosphere is roughly equal to that of Mars at an altitude of about 30 kilometers (18.6 miles) above sea level. This means that if you were at this altitude on Earth, you would experience a similar atmospheric pressure to that on the surface of Mars.
A man on Mars would weigh 38% of his weight on the Earth. This means that to find out a man's weight on Mars, you have to multiply their weight by 0.38. example: 100 pound man on the Earth weighs 100 X 0.38 = 38 pounds on Mars
if someone leaves Earth and then goes to Mars they would not have a loss or gain of eyes
Actually, Mars is smaller than Earth. Mars is only three-fourths the size of Earth, so 75% of Earth would fit in Mars.
The diameter of Mars is about 53% of Earth's and the surface area is close to 38% of Earth's. When you put the numbers into a percentage, the surface area really seems small, but it is equal
