Why is Earth the only planet with life?
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..
What is the nearest planet that can support life?
(CNN) One of the planets that orbits around Proxima Centauri, the closest star to our sun, had been thought to exist within what astronomers call the habitable zone.
Can Venus support human life?
To date, no definitive proof has been found of past or present life on Venus. … With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet.
How does Earth look like?
From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. The blue part is water. … Mapmakers use the line to divide Earth into two halves.
What planet can support life Why?
Scientists have made a “world first” discovery on a distant planet that hosts both water and temperatures which could support life. Water vapour has been detected on a potentially habitable super-Earth known as K2-18b, located about 110 light years away.
Is Earth the only planet with life?
Earth is the only planet in the universe known to possess life. The planet boasts several million species of life, living in habitats ranging from the bottom of the deepest ocean to a few miles into the atmosphere. And scientists think far more species remain to be discovered.
How do we live on Earth?
Earth’s atmosphere is the right thickness to keep the planet warm so living things like us can be there. It’s the only planet in our solar system we know of that supports life. It is mostly nitrogen, and it has plenty of oxygen for us to breathe.
What planet can we breathe on?
Because the atmosphere of Venus is mostly carbon dioxide, oxygen and nitrogen — ordinary breathable air — would float. The air that’s holding you up is also the air that you can breathe. The lifting gas is your environment.”
What is the most dangerous planet?
Venus0.015% 0.007% 3.5% 64% Page 2 Venus is the most dangerous planet in the solar system: its surface is at 393°C, hot enough to melt lead. It’s even hotter than the planet Mercury, which is closest to the Sun. Venus’ atmosphere is acidic and thick.
Where do we live on Earth?

What is so unique about planet Earth?
It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70 percent of Earth’s surface. Earth’s atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe.
Does any planet have oxygen?
Among the planets, Earth is unique for its oxygen-rich atmosphere. None of the other terrestrial planets contain much oxygen in their atmosphere, despite oxygen being a rather common element in the cosmos.
What is the planet of life?
EarthEarth is the third planet from the Sun, orbiting at a average distance of 150 million km from the Sun. This distance is also known as one astronomical unit (1 AU).

What other planet can humans live on?
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.More items…
Does Mars have oxygen?
Mars has only a thin atmosphere, with a surface pressure less than a hundredth of the Earth’s. Even worse, it is 96% carbon dioxide with only about 0.1% oxygen. … The carbon monoxide would be unwanted, and would be vented back into the martian atmosphere.
Will humans go extinct?
The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9%, are extinct. … Humans are inevitably heading for extinction.
What planets could contain life?
A 2015 review concluded that the exoplanets Kepler-62f, Kepler-186f and Kepler-442b were likely the best candidates for being potentially habitable. These are at a distance of 1,200, 490 and 1,120 light-years away, respectively.
What is the hottest planet?
VenusVenus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
Could a human survive on Mars?
However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.16% oxygen. … Human survival on Mars would require living in artificial Mars habitats with complex life-support systems.
Is there oil on Mars?
If Mars possessed an Earth-like biosphere in the past, Mars may contain subsurface deposits of oil and natural gas indicating past life. … Subsurface oil and natural gas on Mars would probably cause seepage of hydrocarbon gases such as methane at favorable locations on the Martian surface.
Is Earth the only planet with water?
Earth is the only known planet to have bodies of liquid water on its surface. Europa is thought to have subsurface liquid water. … Evidence points to water on other planets in our solar system. In 2015, NASA confirmed that liquid water flows intermittently on present-day Mars.
