Because of Mars' very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however. At the Viking II Lander site, frost covered the ground each winter.
There is no rain on Mars because the low temperatures and pressures mean water can only exist as vapor or ice (although it may have have rained in the geologic past say scientists). Snow occasionally forms in the upper atmosphere but does not reach the ground writes Universe Today.
Once upon a time (about 3.7 billion years ago, to be exact), there was rain on Mars. In fact there was enough liquid water on the Red Planet to create vast valley networks and overflowing crater lakes. But these conditions didn't last long. The poor planet lost its atmosphere and became a frozen wasteland.
Sulfuric acid rain forms in Venus' atmosphere but evaporates before it can hit the ground. Carbon dioxide, or dry ice, drifts down like snow on Mars. Jupiter has become known for its helium rain, and ammonia “mushball” hail and methane rain down on Titan. Steady rains of tiny, glittering diamonds may fall on Neptune.
Mars does have an atmosphere, but it is about 100 times thinner than Earth's atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.
For example, like Earth, Mars has seasons, meaning seasonal changes in its atmosphere and weather. But the Martian atmosphere is much thinner than Earth's, meaning atmospheric pressure is so low that the blood of any unprotected visitor would boil.
There is only one planet where gaseous oxygen is found: Earth! And the only reason that Earth has oxygen is because Earth has plants that do photosynthesis.
On saturn, it literally rains diamonds.
Tidally locked hot Jupiter WASP-121b has an atmosphere so hot on one side that it breaks down water molecules and rains rubies and sapphires.
The diamond rain phenomenon is believed by some scientists to take place on Uranus and Neptune in our solar system. It is thought it exists some 8,000 km below the surface of our ice giant neighbours, created from commonly found mixtures of hydrogen and carbon, squeezed together at incredible pressure.
Mercury will be swallowed by the Sun during its first red giant phase. Venus may survive the first phase, but will be consumed during the second giant phase. In all but the direst scenarios, Mars will survive the Sun's final stages of evolution.
The atmosphere of Mars is mostly carbon dioxide, the surface of the planet is too cold to sustain human life, and the planet's gravity is a mere 38% of Earth's.
But on Mars, carbon dioxide is 96% of the air! Meanwhile, Mars has almost no oxygen; it's only one-tenth of one percent of the air, not nearly enough for humans to survive. If you tried to breathe on the surface of Mars without a spacesuit supplying your oxygen – bad idea – you would die in an instant.
Glaciers made of nitrogen ice creep across its surface, hazes cycle through its puffy atmosphere, and dark organic compounds rain down. Pluto's hazy skies form a halo around the dwarf planet in this backlit image taken by New Horizons.
Temperatures on Mars average about -81 degrees F. However, temperatures range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F. over the lower latitudes in the summer.
An atmospheric daytime high might be -3° Celsius (26° Fahrenheit), while a nighttime low might be -96° Celsius (-140° Fahrenheit).
Mars has a reddish color because of the iron oxides (rust) on its surface.
So, Mars is red because it has a layer of rusty dust covering its entire surface! Mars has some of the largest dust storms in the galaxy, in which the red dust gets whipped into the light atmosphere surrounding the planet.
The planet, known as HD 189733b, is a gas giant with a daytime temperature of 2,000 degrees Fahrenheit where it possibly rains liquid glass sideways amid 4,500 mph winds, NASA says.
Venus's surface is covered by toxic acid rain clouds, making it hard to study. Additionally, its surface temperature is more than 860 degrees Fahrenheit, making landing spacecraft an impossibility.
Diamond rain forms when hydrogen and carbon found in the interior of these planets are squeezed by the high pressure and form solid diamonds that sink slowly further into the interior. The research has been published in the journal Nature Astronomy.
Named GJ 504b, the planet is made of pink gas. It's similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive. At 460°F, it's the temperature of a hot oven, and it's the planet's intense heat that causes it to glow.
Although you might think it would be cool, humans could not live on the moon! (Maybe one day in the future…) The moon has almost no atmosphere, so there's no air for us to breathe.
Answer 3: To our knowledge, the Earth is the only planet with an atmosphere of the right density and composition to make life possible. Other planets in the Solar System have atmospheres but they are too thick, hot, and acidic like on Venus or too thin and cold like on Mars.
Mercury is the only planet without any kind of atmosphere. It does, however, have an exosphere, which is made up of gases that are absorbed from the solar wind and emitted from the planet's surface.
