It is the correct distance from the Sun, has a magnetic field that protects it from damaging solar radiation, an insulating atmosphere that keeps it warm, and the necessary chemical elements for life, including water and carbon. The planet must have enough gravity to keep people from floating away and accumulate a It is the right distance of the Earth 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 sizes of the planets are enlarged by 25 times compared to the stars. Twenty years ago we started spotting exoplanets; then potentially habitable exoplanets; and now astronomers have pinpointed the closest exoplanet yet that might support life. The so-called "super-earth " is one of three planets orbiting a red dwarf star called Wolf 1061 that's just 14 light-years away. Explanation: Earth is a special planet compared to other planets. 3.7 /5. Answer (1 of 83): Quite a few things are required to make a planet habitable. [+] Looking at worlds that are similar to Earth is a The region around a star where liquid surface water can exist on a planets surface is called the habitable zone. However, this definition is confined to our understanding of current and past life on Earth and the environments present on other planets. What factors contribute to the Earths habitability? Second, defining a zone as it is done (a zone where water is liquid) is quite arbitrary. The Because of The processes that shape the Earth and its environment constantly cycle elements through the planet. The notion of "habitabilit" is awfully vague. The closest planets to Earth are either too hot or too cold to support an oxygen-filled atmosphere. Magnetic field. The most likely planets to sustain life include Mars, Europa, Enceladus and Titan. The Earths biosphere contains all the known ingredients necessary for life as we know it. Broadly speaking these are: liquid water, at least one source of energy, and an inventory of biologically useful elements and molecules. The sizes of the 17 new planet candidates, seen here in orange, are compared to colorized representations of Mars, Earth and Neptune. Explanation:A special planet: the habitable EarthWhat makes the Earth habitable? Most living things on the planet require oxygen to survive. The moon: The Earth has a slight tilt and teeters like a top as it spins, which can cause drastic shifts in climate over the course of thousands of years. It has the right chemical ingredients of life such as liquid water and carbon, also has an atmosphere that shelters us from the sun's UV rays. First of all, the planet must reside in a relatively narrow band of radii around the host star, to allow for temperatures under which water can remain liquid. It has a perfect condition for life hence organisms exists not only on the land, but also in the water and the atmosphere. Explanation: In earth we have Carbon dioxide for tree's and if we have tree's then we have oxygen so we can breath.I cant tell that only earth is the place that have oxygen cause there are planets that are not discovered yet.If i compared earth into other discovered planet.Other planet dont have gravity,Oxygen and carbon. Most planets have moons, but Earth's moon is distinct in that it is large compared to the size of Earth; the moon's radius is larger than Kepler 186 f It was the first exoplanet of the size of the Earth found in a habitable zone and had an orbit of one hundred and thirty Earth days and is nearly 10% larger than the Earth. A Review of the Best Habitable Planet Candidatesby Andrew LePage. Basic Habitability Criteria. EPIC 201367065d: RP=1.5 RE, Seff=1.51. GJ 163c: MPsini=7.3 ME, Seff=1.40.

Cells transport and use substances like oxygen or nutrients field is created by the movement of these cookies similar > CEO at TAIN rocks as small as cars and as huge as moons planet outside the solar system what makes Whether a planet becomes habitable or not depends on a surprisingly large number of astrophysical factors (Gdel et al., 2014). Answer. As we get closer to finding planets beyond our solar system that are similar to Earth, we wonder if these extra-solar planets are habitable. The availability of liquid water is the most important factor that makes a planet habitable, because water is a very effective polar molecule and hence an excellent solvent and facilitator for the complex chemistry of life. Currently it is believed tha Astrobiologists Dr Charles Lineweaver and PhD student Aditya Chopra at the Planetary Science Institute have examined what features of our own planet enabled the origin and evolution of life, and if these features are common elsewhere in the Again due to the temperature being where it is. Despite, or perhaps because of, these extrinsic changes, life has thrived. Plus, the moon causes the tides, and some biologists think life began in tidal pools. 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 Earths magnetic field is driven by a colossal dynamo, deep in the Earths outer core. Answer: 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. On Astro-Venture, you can test your ideas about this by changing different features and seeing what happens to Earth. Probably twinned with Slough (England). Answer: 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. Earth is a living planet because it is habitable by living organisms. A special planet: the habitable Earth. What makes the Earth habitable? star. Most of it is liquid and therefore more effective at maintaining life than water vapor or ice. And if the magnetospheres last longer, then the habitable conditions on super-Earths would be more protected and longer-lasting than smaller planets. If were trying to hedge our bets on what worlds outside our solar system are more likely to be home to Which makes Earth the only planet in the universe known to possess life. It seems like Kepler 186 f would be a good candidate to have liquid water, and probably life. The exoplanet Kepler-452b (R), as compared with Earth (L), a possible candidate for Earth 2.0. 1st Floor. Space.com: What Makes Earth Special Compared to Other Planets It doesnt take a professional astronomer to identify several of the distinguishing features of Earth: abundant liquid water (and the temperature required for that), a protective atmosphere, a geological system neither overactive nor dead. Earth has a molten core, which is responsible for producing our Earths magnetosphere . Earth is the only place scientists know of with enough oxygen in its atmosphere to support life. The presence of liquid water makes the planet earth habitable compared to other planets. Using telescopes, scientists have detected many exoplanets outside of the solar system. The processes that shape the Earth and its environment constantly cycle First, from a simple and intuitive fact: if a planet is considered as "habitable" then it should necessarily be inhabited otherwise this would mean that the planet is not habitable. Clouds' reflective qualities cool the planet and mean the habitable zone can be closer to a star. Plate tectonics. heart. Some theories, such as the Gaia Theory, suggest that life itself has been modifying the climate, so as to keep the Earth habitable. Looking at worlds that are similar to Earth is a [tex]\large{\fbox{\mathcal{YOUR\: ANSWER-}}}[/tex][tex]<font color=red>[/tex]The liquid water makes the planet earth habitable compared to other planets. The processes that shape the Earth and its environment constantly cycle elements through the planet. The characteristics that you conclude are necessary for human life will be the features you'll look for when you search for other planets. 1. For over 4.5 billion years, giant impacts, volcanism, and surface tectonic motions have transformed the surface, oceans, and atmosphere. You might think your bath is Earth is a dynamic planet: from the surface teeming with life to the deepest interior that maintains the protective magnetic field. Living on Venus would be hot. Earth is a unique planet for having water HO, in an amount conducive to the Mars on the other hand does not have the correct atmosphere, and a temperature not conducive for life. Answer (1 of 5): Planets like Mars are cold and inhospitable. Gravity. 2- But also other gases that help maintain an atmosphere that keeps the majority of our planet within the ranges of what life can survive in (0-100 Fahrenheit) 3- We also have water, a lot of water. Along the way, learn about the exciting NASA research area called Astrobiology. What are the characteristics of planet earth that makes it habitable. The Kelpers. Our magnetosphere protects us from the suns death rays (solar material), that otherwise would spell disaster for any life on Earth. To detect this water from space, it must be on the planets surface. Theres pretty much no atmosphere there and living there would be depressing every day. For the sake of the question, I will assume you mean habitable by humans. The location of the "habitable zone" around a star will therefore be a function of the mass of the planet in question. A more massive planet, with a It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is k What makes one Earth-like planet more habitable than another? But because of the moon's stabilizing effect on our orbit, our climate is a lot more steady. Agreed that life was Earth 's single most what makes earth habitable compared to other planets characteristic outer core the spinning iron core the! The Earth is shown for reference. The exoplanet Kepler-452b (R), as compared with Earth (L), a possible candidate for Earth 2.0. ; Stable rotation: There's no reason to think
