out of the 9 planets ,why are we the only livable one?

Question

how come out of the 9 planets ,why are we the only livable planet?

if a asteriod were 2 have headed 2 earth , and miss it but it started to take earths orbit (like the same distance from the sun)can it start forming water and become livable?

Answer 1

We are the only livable one for our type of lifeform. There might be great gas creatures that live on Jupiter that need the light and energy from lightening bolts to survive. There might be little woolly things that live on Pluto with no eyes but amazing hearing due to the constant lack of light. We are carbon based lifeforms, I seriously doubt that all life is carbon based.

Answer 2

We, the inhabitants of Earth, are the only livable planet because we're in the right place of orbiting around the Sun. Earth is a temperate planet, meaning that it's a warm place (not too hot or not too cold). If Earth were close to the Sun, then the water would evaporate, and life as we know it wouldn't exist. If Earth were far from the Sun, then the water would freeze, and, just like the Earth that would have been close to the Sun, life as we know it wouldn't exist.

As for the question on an asteroid getting into Earth's orbit after missing its impact, it can't start forming water and become livable very naturally. If you want a planet to have water so that it can be more habitable for all lifeforms (including humans), then you must terra-form (make it more like Earth) it with advanced technology.

Answer 3

Well Earth has things that other planet don't have like water in all 3 forms (gas, liquid and solid), which is one of the things scientists look for on other planets to see if life is vital.
Temperature is also a factor....its kind of like the goldilocks and the 3 bears, when eating the porrage, 1 is too hot, the other too cold and one is just right...same with venus, mars and earth...venus is too hot, mars is too cold and we are just right.
Obviously the further from the sun you get the colder places get.
Our larger planets are gas planets which make it kind of herd to get life going (but scientists are looking at the moons of these planets to see whats there for viable life). So rocky planets are the best really.
Size of planet would probalby be a factor in that the larger a planet is the more gravity which can make it harder for life on the planet to overcome.
Atmopshere....its needs to have specific gases for us to live and it would be the case for life on other planets too.....The smaller something is the less atmosphere it has...eg the moon has practically none so that makes it tricker for life and the atmosphere also regulates temps too (making them more stable)...the less atmopshere the more varied temps are..so a little asteroid would not really be able to support viable life (as we would know it) as it would vary too much in temp (if it were moving like you say it would), temperature varaiations, no water etc etc etc

Answer 4

Reason why we are the only liveable planet -

has to do with our distance from the sun (not to much heat, not to much cold).

has to do with the type of core the earth has (iron/nickle) and because of that has a strong enough gravity to retain its atmosphere instead of letting it escape into space...

has to do with the fact that we have water in abundance on Earth.

Finally, some folks just have all the luck...

ASTEROID question: NO.

You can't just start forming water because you are in the right neighborhood. It takes a lot more than that. Also, most asteroids are way to small to have a significant gravity which would retain gases. Gases... Hmm-m ... hydrogen and oxygen make up water, right? Not to hard to figure out...

Answer 5

Our planet is just at the right distance from the sin so that it is not too hot or too cold. And ours has water which is the most essential ingredient for life. It is said all life came from the water originally so all the other planets don't have water so no life. But the new planet we found might have water and it has some similarities to earth so we might live there one day.

Answer 6

Asteroids and things can't form water, and lots of it deals with an atmosphere.

Earth has an atmosphere, which it allows it to keep relatively cool in daytime and relatively warm at night. This prevents the water that we have from boiling off.

Second, the earth didn't produce water, most of it probably came from comets which impacted billions of years ago, before even the simplest bacterial life.

A good example is the Moon. It's close enough to have nice temperatures, right? Wrong. Because it has no atmosphere, any water which is exposed to sunlight is boiled away. The only water on the Moon is ice in craters which lie in perpetual shadow.

Third, living things need air to breathe. Simple as that.

Answer 7

Regarding the first part of your question, we believe that only 3 planets in our Solar System belong to the 'habitable zone', the area in space that can sustain life. These are Venus, Earth and Mars. Venus and Mars failed for different reasons, Venus became too hot due to global warning, Mars went the other way due to global cooling.

The other planets cannot really qualify for life, as Mercury is too close to the Sun so far too hot for that, while the giants Jupiter, Saturn, Uranus, Neptune have no surface at all. Pluto (who in real terms is a big asteroid, not a real planet) does have a surface but is far too cold for life to begin).

As for the second part of the question, asteroids are small objects with low masses, so they cannot sustain atmospheres for life to begin in them.

Answer 8

The planets closer to the sun are too hot, the planets further away from the sun are too cold. Where the earth is happens to be just right where water can be a liquid and not boil away or freeze.

Answer 9

there is 125 livable planet,one per universe,when I made this planet it was 240 degrese day night it would be 60 degres.when I landed it was like.I was thinking of building another solar system here I was wondering i f the earth men and women would interested .Di you now how it took me to build this solar system.I have cafigaratio for new solar system ,with new sun,and new moon.seven planets total sincerely JAMES RITCHIE

Answer 10

An asteroid would not have enough mass to retain an atmosphere, and without an atmosphere, any water would vaporize and vent into space.

Other planets are either too massive, too cold or too hot to sustain life as we know it, and the temperature is mostly linked with how close or far they are from the sun.
