Content: Within the Milky Way Galaxy are the planets that most children learn while they are in school, although the actual planets seem to be expendable, at least in the case of Pluto. The planets within our solar system as most of the current generation learned them include: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto (now recognized not as a planet but as a dwarf planet.) Life forms that have the same requirements as the human race are unable to sustain themselves on any of the above listed planets with the exception of Earth. We will begin with Earth as we know it to be the only planet that has the ability to sustain life. Located as the third planet from the sun – some 93 million miles or one Astronomical Unit away, the Earth is the fifth largest planet in the solar system and has just one moon. The mass of the planet Earth is 5.98 x 1024 kg and has an average density of 5520 kg/m3. As such the Earth is known to be the densest of all the planets contained within the Milky Way galaxy. While temperatures on the Earth’s surface vary considerably most of the face of the planet is hospitable to life with temperatures ranging between -127 degrees Fahrenheit and 136 degrees Fahrenheit. The atmosphere of the planet Earth is made up of a variety of gasses which are primarily made up of 78% nitrogen, 21% oxygen, .9% argon and .03% carbon dioxide.
