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.
99 days on earth is one year on mars
None, because only half an Earth can fit inside of Mars.
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.
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
A year on Mars is equal to 687 Earth days. That is about 2 Earth years.
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
earth is 1 planet away from mars
Mars is 5962 km in diameter smaller than Earth, which is 12756 km in diameter. Mars is 6794 km in diameter. So 12756 km - 6794 km = 5962 km.
