There are a couple of reasons. First, the gas giant planets are much larger, and therefore have much higher gravity. They CAN hold on to their atmosphere.
Secondly, Mercury is very close to the Sun, and the radiance of the Sun and the volume of the "solar wind" from up close there has blown whatever atmosphere Mercury MAY have had off into space. The gas giant planets are much further away, and the power of the Sun is correspondingly much less. Imagine standing right in front of a fan - and then moving back several feet. You'll feel the difference.

∙ 10y agoThe whole idea of a black dwarf is that it no longer emits energy. A black dwarf is the final stage of a white dwarf, after it cooled down to the temperature of the environment, which at that time will be a fraction of a kelvin. Black dwarves don't currently exist; the Universe is too young for that, and white dwarves didn't have the time to cool down that much.

Mercury is too hot. Venus is also too hot. Jupiter has too much atmospheric pressure, along with Saturn, Uranus, and Neptune. Anything farther than Mars is too cold, and Anything closer than Earth is too hot.

should really be asking, "How is it possible for living life to live on a planet ?"
and "What does it take ?"

∙ 12y agoBecause the gas giants have huge gravitational force compared to the one on mercury
Wiki User
∙ 13y agoThere are no solid landmasses on any of the gas giants. Unless life was able to develop on the rocky core and was able to survive the huge pressure and temperature, no life can survive there.

escape into space ... on account of the thing called 'gravity'.

Do Atheists believe there is life on other planets?
Atheism isn't a belief system; it is the not believing there is a god or gods. Some atheists probably believe there is life on other planets, some don't and some don't know.
What are the chances there is NOT life on other planets?
Space astronauts went to the planets to be sure there is no life on planets
Is it possible that some planets have life on them and suggest a reason why we are unlikely ever to visit these life forms.?
the planets containing life form other than earth may have a dangerous species, or the planet itself may be dangerous.
What is the reason that life is less likely on the outermost planets compared to the inner most planets?
What is the reason that life is less likely on the outermost planets compared to the innermost planets
Do any other planets have an atmosphere like earths and if they did could it support life?
At the moment, no planets are known to have conditions similar to Earth's for supporting life. If there planets similar to Earth, there would definitely be living organisms of some sort. On the other hand, there is slightly less chance of sentinent life such as our own species existing.
What book is available which deals with life on other planets?
There are several books that deal with life on other planets. Some titles include Is There Life on Other Planets by Gregory Vogt, and The Mystery of Life on Other Planets by Chris Oxlade.
Do planets have life?
Some do some don't, Earth does but not many have air or water to have life on them.
What are some things in the outer planets?
gas no life and they are bigger than the inner planets
Do other planet or moons might support life no or yes?
Yes,Other planets could scientists believed some life were on other planets and signs of life
Was there ever life on any other planets?
No one actually found any human life on any other planets yet, but there is known to be some plant life out on mars.
Do Atheists believe there is life on other planets?
Atheism isn't a belief system; it is the not believing there is a god or gods. Some atheists probably believe there is life on other planets, some don't and some don't know.
Is there a life in other planets?
Almost certainly some other planets have tiny one-celled organisms, at least.
Do Christians believe in life on other planets?
Some do, some don't. Some Christians claim that if we discover life on other planets, Christianity is proved wrong. But it is not so, because God doesn't say in the Bible if earth is the only planet that can support life.
Do hindism people believe there is life on other planets?
yes some
What are the chances there is NOT life on other planets?
Space astronauts went to the planets to be sure there is no life on planets
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.
Is their other planets that have life on them?
NO- People have found water on other planets but there is no life there.
