special characteristics of planet earth which make it suitable for sustaining life Currently, our only guide to what type of star is likely to host an earth-type planet suitable for human habitation without special environmental protection is our own because elements heavier than hydrogen are essential to make rocky planets like earth and large stellar flare-ups can harm planetary life with hard radiation.

Earth is one special planet—and it seems the more we learn, the more we know it it doesn't take a professional astronomer to identify several of the distinguishing features of earth: abundant liquid water (and the temperature required for that) [c]ertainly there will be other planets that support life. Such planets would definitely not be good places to look for life at the other end of the spectrum, an object that is too small and of too low a mass (such as mercury, or earth's moon) won't have enough gravity to hold an atmosphere typically, the more massive the planet, the more massive the atmosphere. In this video lesson you will learn about water and its unique properties you will also develop an understanding of how these properties make. Orbit a star that remains stable in output for billions of years be at a distance from the star that results in its achieving a suitable temperature so its surface water is a low mass, cool star can only sustain life on planets close-in, while higher- mass, hotter stars make their planets too hot close-in and life can only be sustained.

While still assuming that life requires water, they hypothesize that earth may not represent the optimal planetary habitability conditions for maximum biodiversity in other words, they define a superhabitable world as a terrestrial planet or moon that could support more diverse flora and fauna than there are on earth, as it. The planet is about the same size as earth, and it may have a similar surface temperature, making it a temperate world that could support life every 99 days, it completes the special properties of this system means that we are contributing our bit on the search of an earth 20 other notable discoveries. Chemistrymany astrobiologists believe that if we find living organisms on other planets in our solar system and elsewhere in the universe, they will be recognizable to us as life have on earthwater has many unique physical and chemical properties that make it well suited to support the complex chemistry required for life. The four closest to the sun — mercury, venus, earth and mars — are the terrestrial planets the density of its atmosphere makes the air pressure at the surface 90 times that of earth's the atmosphere, made of mostly nitrogen, oxygen and carbon dioxide, is crucial to earth's ability to support life.

No other known planet is quite like earth it is covered in liquid water, sits within a habitable proximity to the warm glow of a sun and still retains an atmosphere capable of sustaining life however, it could have turned out much differently, leaving the planet to float aimlessly, desolate and lifeless, across the. Planet earth is a dense, rocky ball about 7920 miles (12750 km) across it is one of nine planets circling our local star, the sun earth is the onl earth is the only planet we know of that can support life from space, its surface earth's oceans cover almost two-thirds of its surface, making the planet look blue from space. I'm curious what a planet needs to support life i've got a list of a bunch of answers other people have given on the internet and their own research, but i want to see if this list has anything we can remove from it (or add to it), and maybe make one final, good-as-we-can-get-it list because otherwise, i'm.

Given that liquid water is such an essential ingredient for life here on our planet, astronomers are eager to find it on other worlds outside our solar system the presence of liquid water on an exoplanet could mean that life has thrived there as well, so that makes these seven planets now top candidates in. After the earth, mars is the most habitable planet in our solar system due to several reasons: its soil contains water to extract it isn't too cold or too hot there is enough sunlight to use solar panels gravity on mars is 38% that of our earth's, which is believed by many to be sufficient for the human body to adapt to it has an. The evolutionist must believe that life is inevitable wherever conditions are suitable for life, but creationists understand that even if conditions on another planet could sustain life, life there is not possible--unless god created life there or permitted life somehow to travel to that planet from earth while we. But not all of the science it features is junk some researchers really do think that earth's magnetic field deflects ionising particles from the sun, which would otherwise wear away earth's atmosphere if they are right, then without a magnetic field our planet will lose its atmosphere too, and all life will die.

He agreed that life was earth's single most impressive characteristic none of this is a revelation, but understanding what's special about earth is crucial for finding other planets out there and predicting what they might be like the fact that earth hosts not just life, but intelligent life, makes it doubly unique. Earth is the third planet from the sun and is the largest of the terrestrial planets the earth is the only planet in our solar system not to be named after a greek or roman deity the earth was formed approximately 454 billion years ago and is the only known planet to support life facts the moon diagrams. Data from kepler space observatory suggests planets capable of supporting life are far more common than previously thought the most common type of star in the galaxy, making up about 80% of the stellar population – very frequently harbour earth-size planets, including in their habitable zones. In the dark corners of our galaxy, there are billions of rogue planets roaming around, starless – can they support life the sun gets a lot of good press yes, we do if the sun were to suddenly turn off, earth would freeze over into an ice ball our planet's geological thermostat – the carbonate-silicate.

A special planet: the habitable earth what makes the earth habitable 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 the processes that shape the. We're pretty sure there's no chance of life on this planet, said mit planetary scientist sara seager so what makes a world such as ours able to host life why is earth so special there are a few key ingredients that scientists often agree are needed for life to exist — but much debate remains as to what. Mars being habitable, it turns out, doesn't mean it actually has a habitat source: jupiter's moon europa is one of the most likely places to harbour life outside earth, with its liquid oceans and gravitational energy sources pictures and but could they also act as the solvent needed to support life 'if there.

As of now, we do not have any concrete proof of the existence of life anywhere else in the universe 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 in other words, since we haven't found. That ought to make the planet blisteringly hot, except that ross 128 is a red dwarf , a far smaller, far cooler star than our yellow, so-called class g star by contrast, appears to be a quieter star, with less frequent flaring — which is characteristic of more mature red dwarfs, further along in their life cycles.

Originally answered: what characteristics of earth are necessary for supporting life the most the magnetic sphere around the planet- this deflects the solar winds and allows the atmosphere to remain in place principally the fact that there exists liquid water, which is, if not amazing, at least unique to the solar system. Identify several factors that make life anywhere possible discuss why earth is the only apparent planet in the solar system capable of supporting life gain an appreciation for how special our planet really is compare and contrast planet features within the solar system use a spreadsheet to analyze planetary data. They called their idea the rare earth hypothesis astronomers disagree on just how rare life is in the universe, but earth nonetheless boasts several features that make it just right for life as we know it: the right ingredients: a planet needs liquid water, an energy source and chemical building blocks like carbon, oxygen,.
