At just 0.38 of the Earth standard, a person who weighs 100 kg on Earth would weigh only 38 kg on Mars. This difference in surface gravity is due to a number of factors – mass, density, and radius being the foremost.
The size of mars
This image compares Mars and Earth in their correct relative sizes. Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers).
How long does it take for mars to orbit the sun
IT TAKES 387 DAYS
How long does it take TO rotate once
24 hours, 37 minutes.
The atmosphere of Mars is less than 1% of Earth's, so it does not protect the planet from the Sun's radiation nor does it do much to retain heat at the surface. It consists of 95% carbon dioxide, 3% nitrogen, 1.6% argon, and the remainder is trace amounts of oxygen, water vapor, and other gases.
In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).
The moons of Mars are Phobos and Deimos. Both moons were discovered in 1877 by Asaph Hall and are named after the characters Phobos (panic/fear) and Deimos
I picked this planet because it is were we are going to live in the future
