Up to this point, so far as we know - none. The search for elemental life forms - or even the "ingredients" that might make it possible - on other planets is an area of great interest in astronomy right now. One of the most tantalizing questions is: If there is no life on Mars (and given what we've been able to determine so far, it doesn't appear so) was there ever life on Mars? That may be the #1 question in planetary science they would like to answer at the moment.
What else can I help you with?
What is the differences between your planets and other planets?
earth is the only planet known to house liquid water and life
Why did God create life on other planets besides earth?
Scientists say that life can be expected to have evolved on other planets, wherever the environment is not so hostile that life can not be supported. They say that in this vast universe there must be many such planets that can support life and that some are likely to support intelligent life forms even more advanced than humans. Whether we believe that our God created the life on other planets is a matter of human faith. No doubt any intelligent life on other planets will never have heard of Earth's gods.
Why is it important for humans to explore other planets beside earth?
It is important in case there is life beyond Earth.
What percent of water is on the earth?
75% Is this a trick question? All water is on the earth. Except some scientists have discovered ice on a few planets, but not in it's liquid state.
Earth is different from the other planets in our solar system because it -?
Because (as far as we currently know) Earth is the only planet in our solar system that supports life.
Is there any life on planets?
No life has been detected except on the planet earth.
Is ther any life on any planet?
not that we know of. but the 8 planets we have, all of them dont except earth has life.
Is there life on other planets except on earth?
We do not know. So far, organic molecules have been located on planets and in distant stars, but this is not proof that organic life exists there.
What kind of life exist on other planets?
As far as what we know today, there is no life on any planet anywhere, except the Earth.
Do all planets except earth rotate?
All planets rotate. Even earth.
What other planets-other then earth-may support life?
Life probably does not exist on any of the known planets (except earth). But if life does exist on one of those planets, it would probably be on Mars. Venus is way too hot, Mercury does not have an atmosphere, and the other four planets are made up almost entirely of gas.
What planets can't we live on?
All of them, except for Earth.
Why are inner planets also called rocky planets?
The inner planets, except earth, are made up of rocks. They have a hard surface. The earth would be one of these except we have water. The outer planets are gas giants and do not have a solid surface.
Which planets is cold and surrounded?
All except earth and venus.
What planets were named after god?
All of them except Earth and Uranus.
What planets do not have life?
All, but earth.
Why is there no life on the planets?
