Why earth is the only habitable planet?
earth is the only known habitable place because its the only one with water, food, and has the right temperature range for life as we know it, but scientists are discovering planets a lot like earth, but none are habitable for humans
How did ancient scientists know that there are nine planets in the solar system without having any special equipment?
Ancient astrologers only knew about 5 planets plus Earth. They knew about the 5 planets from visual observation.Furthermore, there are only 8 planets in our solar system.
What sphere does the earth have that no other planets have?
The Earth has a biosphere, which is the part of the Earth where life exists. This includes all living organisms and their interactions with each other and their environment. Other planets in our solar system do not have a biosphere as they lack the conditions necessary to support life as we know it.
How many planets are habital?
Other than Earth, no planets have been confirmed to be habitable. We do know of planets in other star systems upon which liquid water could theoretically exist but we can't measure the composition of the planets atmospheres therefore we can't know for certain whether or not they are habitable.
Why is there not life on other planets?
Life, as we know it, has very specific and narrow optimal conditions and so far only Earth has been demonstrated to have them. However, scientists have not ruled out the possibility of a planet in another solar system having life.
Is there any other life on any of the planets that you know of?
We don't know about any other other place, besides Earth, that harbors life. But many scientists think that there is life on other planets.
How do scientists know that planets are closer to earth than the stars?
not a clue
Why do scientists believe that earth is the only planet that can sustain life as you know it?
You need water to live and other planets don't have water
Is there life like aliens on other planets?
We don't know if there is life on other planets or not. Most scientists suspect that there probably is life somewhere in the Universe other than Earth, but we've never found any yet.
What do scientists know about the outside planets?
They are gas planets
How old is the other earth?
There are many planets in the universe, but as far as we know there is only one Earth, therefore I do not know to which "other earth" you are referring.
Is there life in any planets?
Yes, only on the Earth. We don't know if the other planets have life
How do scientists know that there are planets circling other stars?
They have been located and identified as such by astronomical techniques.
Could other earth-like planets exist in the universe?
Yes, it is possible that there are other Earth-like planets in the universe. Scientists have discovered thousands of exoplanets, some of which are in the habitable zone of their star where conditions might support life as we know it. Future missions and advancements in technology may help us identify more Earth-like planets.
What do scientists infer about the conitions necessary for life on other planets?
life and order in the court u know
Scientists look for what molecule when they are investigating the possibility of life on other planets?
Scientists look for molecules such as water, methane, and organic compounds like amino acids or nucleotides when investigating the possibility of life on other planets. These molecules are considered essential for life as we know it.
How many planets like earth are there?
If by "like Earth" you mean habitable (that we could live on, without spacesuits, domes or other technological adaptations): there aren't any in our solar system, and none yet elsewhere that we know of. But scientists keep searching; the universe is a pretty big place, and odds are there are multiple other Earthlike planets out there somewhere.
