The Similarities Between Mars And Mars

Good Essays

Mars, the red planet, and fourth planet from the sun. What is Mars really like, is it cold or hot, wet or dry? Can humans live on Mars, and if so how? For decades scientists have been studying Mars, they have been using rovers and from there they collected data, samples, and took pictures. These rovers study Mars’ atmosphere, temperatures, weather, if it has water, and a lot more. With all of the data the scientists have gathered we know that Mars’ atmosphere is a lot different than our, yet still has similarities.
Even though Earth and Mars are in the same solar system and orbit the same sun, Mars’ atmosphere and the planet itself is a lot different from Earth. Mars is 142 million miles away from the sun, with a year being 687 days long. It is about half of Earth’s size, and is one tenth of Earth’s mass. Mars’ atmosphere is carbon based, containing 95.3% carbon dioxide, and also it only has .3% water vapor (Source for %). The average temperature on Mars is -81 degrees Fahrenheit which is approximately -62 degrees Celsius (NASA). Mars’ atmosphere is also very thin, so it does not “allow liquid water to exist at the surface for long” (Newsela). Also Mars has a lot less gravity, Earth has 62.5% more gravity than Mars does (NASA). Mars’ environment would not be very hospitable for human life.
Earth also differs a lot from Mars, Earth is 78.1% nitrogen, and 20.9% oxygen, and isn’t carbon based (Source for %). While Mars only is only .3% water vapor, Earth is 1-4%
