Rain and snow pull gunk out of the air on their fall to Earth. The same is true on Neptune and Uranus. Neptune gets more snow, thus there's fewer particles hazing up the air.
Saturn's moon Enceladus has geysers that shoot water vapor out into space. It then freezes and falls back to the surface as snow. Some of the ice also escapes Enceladus to become part of Saturn's rings.
Mars' ice caps are made mainly of water ice, although Mars is cold enough to also have frozen carbon dioxide, or dry ice. Carbon dioxide is in the Martian atmosphere, and it freezes and falls to the surface of the planet as dry ice snow.
A new study has found that “diamond rain” may be more common on ice giant planets like Neptune and Uranus than previously thought. For the first time, scientists were able to observe diamond rain as it formed with their experiment designed to mimic the extreme temperatures and pressure found on those planets.
Uranus - Minus 320°F (-195°C) Neptune - Minus 330°F (-200°C) Dwarf Planet Pluto - Minus 375°F (-225°C)
Neptune is the second coldest planet, Uranus's atmosphere makes it the coldest planet with temperature of minus 224 deg.
Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.
Uranus and Neptune are two of the many exciting and mysterious objects in our universe that the James Webb Space Telescope will soon begin to explore. Temperature and pressure conditions are so extreme on these planets that carbon atoms could be crushed into diamonds in their atmospheres.
A massive gas giant orbiting a star about 855 light-years from Earth, WASP-121b may have metal clouds and rain made of liquid gems, according to new research. A study showing how water atmospherically cycles between the planet's two sides published Monday in the journal Nature Astronomy.
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.
Venus: Venus has a very dense atmosphere that contains about 97% carbon dioxide, a greenhouse gas that traps the Sun's radiation and heats the planet's surface to a whopping 872°F (467°C). The surface of Venus is the hottest in the solar system! Venus is too hot to have any type of ice on it.
Neptune has nitrogen at its two poles. Now, when the gas nitrogen freezes, it looks like pink snow!
Uranus and Neptune
It's really cold that far away from the Sun. So, these chemicals might be frozen or trapped in crystals of ice. Because of this, Uranus and Neptune are called "ice giants."
Since Mercury has hardly any atmosphere, it does not have weather like storms, clouds, winds or rain!
Pluto is the only place other than Earth in our solar system that's known to have white-peaked mountains, but these white caps aren't made of snow. Instead, they're made of methane frost.
Like Earth, the Red Planet experiences snow and frost and is home to water ice. So, in a way, its winters look like ours. But that's about where the resemblance stops. In a Martian winter, the planet's average temperature—already a frozen minus 80 degrees Fahrenheit—plunges to 190 below.
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.
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.
But the most fabulous potential space fortune may be “the diamond planet,” the more technical name of which is 55 Cancri e. This exoplanet is twice the size of earth and may be made up of one-third diamonds. That diamond cache could be worth $26 nonillion (that's 30 zeros), according to “The Filthy Rich Guide.”
Scientists have found evidence of cubic zirconia in Moon rocks, showing that the universe not only holds diamonds, but its own fire-safe knock-offs. Space could be absolutely shimmering with precious stones, though Mao emphasizes that they probably aren't quite like the ones in earthlings' jewelry boxes.
NASA has taken a closer look at 55 Cancri e, an exoplanet that earned the nickname "diamond planet" due to research that suggests it has a carbon-rich composition. Even if we could reach these diamond exoplanets, they wouldn't be appealing places to visit.
The predominant blue color of the planet is a result of the absorption of red and infrared light by Neptune's methane atmosphere.
Jupiter formed less than 3 million years after the birth of the solar system, making it the eldest planet. Saturn formed shortly after, amassing less material since Jupiter gobbled such a large portion of the outer disk.
Venus is the brightest planet in the Solar System.
Similar in structure and size to Earth, Venus's thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system.
