Brainly User It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon. Therefore, in order to establish the criteria of habitability of a planet (or a natural satellite), the conditions that support life on Earth also need to be extrapolated for other celestial objects. SETI Institute 29,390 views. Here are a list of the 9 planets in their order in the solar system: 1. Ask your question. The location of the “habitable zone” around a star will therefore be a function of the mass of the planet in question. The definition of “habitable zone” is the distance from a star at which liquid water could exist on orbiting planets’ surfaces. Geological and biological processes cause energy and the elements necessary for life-carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus- to circulate through global “reservoirs.” These reservoirs are the biosphere (the living portion of our planet), the atmosphere, the ocean, and the solid Earth. 2. scientists Find an answer to your question What are the characteristics of planet earth that makes it habitable 1.
