Solar System Planets Habitability Analysis

This article will detail my personal anaulysis of the potential habitability of some of the planets and moons in our Solar System. I will focus my analysis on the planets Earth and Mars, and the moons Europa, Enceladus, and Titan.

Planet Earth

Planet Earth is special and unique. There are 18 criteria that Earth meets that contributes to its status as a habitable planet. The criteria are as follows:

[1] The Earth orbits in the habitable zone of the Sun – the zone where liquid water is possible given a sufficient atmosphere
[2] The Earth is not tidally locked with the Sun – meaning one side of our planet does not always face the Sun
[3] The Earth has an axial tilt of 23.5 degrees – this tilt makes it possible for Earth to have seasons
[4] The Earth has an orbital eccentricity of 0.0167 – this is a measure of how closely an orbit is to a perfect circle – a perfect circle = 0
[5] The Earth is a Terran-sized planet
[6] The Earth has a mass of 5.972 Sextillion metric tons
[7] The Earth has a diameter of 7,918 Miles
[8] The Earth has a density of 5.52
[9] The Earth has gravity of 9.807 meters per/second/second
[10] The Earth has an atmosphere comprised of 78% Nitrogen, 21% Oxygen, and 1% Argon
[11] The Earth has an atmospheric pressure at sea level of 14.7 pounds per square inch
[12] The Earth’s atmosphere has an ozone layer that protects us from UVR radiation from the Sun
[13] The Earth has a magnetic field of 0.25 to 0.65 gauss – this field protects us from the solar wind that would destroy the ozone layer
[14] The Solar flares from the Sun are moderate compared to some other stars
[15] The average surface temperature on Earth is 57 degrees
[16] The Earth has oceans of liquid water
[17] The Earth has a rocky surface
[18] The Earth is home to a variety of plant life that remove carbon dioxide from the atmosphere and exhale oxygen into the atmosphere
