Content: In combination with the availability of water and the abundance of oxygen these conditions make Earth a suitable planet for life. Comparing Earth to Other Milky Way Planets
So if the conditions listed above make Earth so hospitable to life why are other planets within the solar system considered so inhospitable to life? It is the combination of the factors listed above that make Earth hospitable to life, the balance of the gasses and chemicals needed to sustain cell life and generation is optimal within the Earth’s atmosphere, the temperature is comfortable enough for the most part to be able to sustain life, water is readily available to maintain appropriate levels of hydration (we are composed of mostly water you know) and all of these elements come together to allow life to flourish. So what is it about the other planets that make them inhospitable to life that resembles the human and animal races that thrive on Earth? Mercury
Mercury is the planet closest to the sun in the Milky Way Galaxy meaning that the temperature makes the planet inhospitable by itself with blazing hot temperatures in the day and freezing cold temperatures at night. The lack of atmosphere around Mercury means that there is no ability for the planet to maintain heat and temperatures would move from one extreme to the other very quickly. Mercury lack of atmosphere also means that the essential elements needed to support life in any form are missing. Mercury is also a particularly small planet measuring in at around one-third the size of the planet Earth meaning that even if it were able to support life it would likely never approach the populations that we see on the planet Earth. The gravity on Mercury is also considerably less than the gravity on Earth meaning that living conditions would be altered dramatically for any life forms that were able to sustain life in Mercury’s atmosphere. As for the moon that controls so much on the planet Earth?
