Too close to the star, and water will boil; too far, and it will freeze. Now NASA has shared an image of an Earth-like planet that has many of the characteristics needed to sustain life. 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. what are the factors that make The planet habitable - 24908016 ….

What makes the Earth habitable? In a 2014 conference at the NASA Ames Research Center, Dr. Chris McKay, a planetary scientist and founding member of The Mars Society, presented a list of Mars’ most important resources that early Martian colonists would exploit to make the planet habitable. He agreed that life was Earth's single most impressive characteristic. It helps them think about what life might be like in the future. It helps them decide whether or not the 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. One of the most basic assumptions that astronomers make when searching for a habitable planet is that it has to be terrestrial. Furthermore, various geophysical and geodynamical aspects, the radiation and the host stars plasma environment can influence the evolution of Earth- While not all volatiles make for habitability, water ice can if temperatures are right. The habitable zone (HZ) is a shell-shaped region of space surrounding a star in which a planet could maintain liquid water on its surface. SETI Institute 29,390 views. Ancient rocks provide evidence of the emergence of oxygen in the atmosphere and of a frozen Snowball Earth. These are just a few of the items on the long list of features that make Earth more habitable than the average planet. 1. Here are a list of the 9 planets in their order in the solar system: 1.
