Mercury: Too close to the sun.
Venus: Hell in the form of a planet.
Earth: Perfect climate conditions, oxygen in atmosphere, etc.
Mars: Cold; uncertain if survival is possible on this planet.
Everything else is just way too cold.
Aside from all that are the rigors of space. Nuclear radiation bathes almost every square inch of the solar system corrupting the DNA of living things. Most planets aside from gas giants or the Earth don't have Van Allen belts which filter it out. Another point is that gravity is a requirement to keep our bodies operating healthy and how much gravity is enough is still an issue for debate.
It is not possible to live on other planets because there is no oxygen for humans to live. We would also need abundant water, plants, other animals, a reasonable amount of gravity, and the right temperature.
A planet would need a mixture of gases with a good ratio for breathing. We need maybe 30% oxygen and about 60% nitrogen. The nitrogen is inert and thus not a poison as long as there is enough oxygen.
It is entirely possible for life forms to exist on other planet. However, we are so lucky with our placement in the galaxy (Distance from the sun) so we can survive here on Earth. The chances are that there is a planet around the same distance from a star as Earth is. They might not be the very intelligent though, e.g. they could be still in the prehistoric period right now (Dinosaurs). Or they could be very intelligent but haven't discovered light speed yet, like us.
Additional comment to the very good answer above:
Actually, there is no reason to assume that life is not possible on any other planet. In fact, on any planet, or moon of a planet, which is warm enough (but not too warm), and massive enough, to have stable bodies of liquid water on its surface, life is, in theory, possible. Some scientists even believe that other liquids may support life, such as the liquid methane seas now known to exist in abundance on Saturn's moon Titan. I said life on other planets is possible "in theory" since how life actually originates is still the topic of heated debate where the realm of science meets the realm of theology. Who am I---who is anyone---to say that at this time with certainty, that in addition to stable liquid water, a "divine spark" is not also necessary for life to arise out of the lifeless raw elements of carbon, nitrogen, oxygen and hydrogen? Therefore, although life is in theory possible on other planets, and exoplanets (planets outside our own solar system) are known to exist which may very well support stable bodies of liquid water, we have no way of knowing at this time---and perhaps we never will---whether or not there is life on those planets. I suspect that there is, but that is only an opinion, and an unscientific one at that.
It isn't that life cant exist on another planet its that the life on other planets would be quite different from a human body form. They have already found life on mars. Not what we think of extra terrestrial but a micro size fish.
well we can't live on the other planet because it has no atmosphere.
It is impossible to live on other planets because of either extreme temperatures, unsuitable pressure, and toxic atmospheric composition.
because of the gravity of the earth sampak to the moon lapus to the sun and go back to the earth
The goldilocks planet does not exist. It is an area in a planets orbit where water is liquid and life could exist. See related question.
It is my personal opinion that Earth cannot be the only planet that has abundant life. I believe that if life is going to be discovered on another planet that it will be the newest plant to be discovered, planet Kepler 186f.
All life as we currently know it cannot exist without water (H2O). Scientists look for signs of water when searching for life on other planets.
There is no recreation on planet Mars because people cannot live there. Mars is a rocky planet that cannot support human life because its atmosphere consists mainly of carbon dioxide. It is the fourth planet from the sun.
Well we really dont know if it is possible if aliens exist....but if god made us in this planet......so its possible there life on other plantes......if you know what i mmean
So far as is known to date there is no life on any other planet in our solar system or elsewhere. That does not rule out the possibility that life may exist on other planets
beause earth is the only planet which has oxygen and other needed sudstances .
1 . Earth is the only planet where life is known to exist..there is no other planet where life can exist !!2. Earth is the third planet which nearest to the sun and it has an atmosphere which consists of hydrogen ,oxygen and carbon dioxide which are required for the existence of human life whereas other planets do not have any such gases!!!
No life has been discovered on other planets yet. However, given the huge amount of planets in the Universe, and the fact that hardly any planet has been thoroughly investigated, it's quite possible that life does exist.
Earth is the only planet which is known to harbour life.
depending on the planet there cannot be living things on other planets
As far as what we know today, there is no life on any planet anywhere, except the Earth.
Would life exist on what planet? Earth? Mars? Yes, even if not human, trees and plant vegitation
its the second planet away from the sun but surprisingly the hottest planet of them all no life form could survive on there it's temperatures can soar up to 500 degrees Celsius
Other than the fact that cycles do not end... the rock cycle cannot end, because if it did...all life on the planet would cease to exist. The rock cycle helps move nutrients to different areas of the planet...
Yes
