Of all the planets in the solar system, only the four inner ones, along with Pluto (which was demoted to dwarf planet status in 2006) are solid. Of these, only Earth, Mars and Pluto have permanent polar ice caps. However, all the planets exhibit anomalies at their poles.
How big is the ice cap on Mars?
Mars has ice caps at both its poles. The north pole ice cap is about 600 miles (1000 km) across -- about the width of Montana! The southern ice cap is about 1/3 this size. Both ice caps are made mostly of water ice, but the southern ice cap has a permanent cover of carbon dioxide ice.
What is the difference between the North Pole and southern ice cap?
The north pole ice cap is about 600 miles (1000 km) across -- about the width of Montana! The southern ice cap is about 1/3 this size. Both ice caps are made mostly of water ice, but the southern ice cap has a permanent cover of carbon dioxide ice.
Where is ice found in the universe?
Ice is common in our solar system, from deposits at the poles of Mercury and the Moon to ice-covered moons and rings around distant Jupiter and Saturn, and comets made of ice and other materials streaming across the spaces between.
What are some examples of frozen matter on other planets?
Mars'poles have abundant amounts of frozen carbon dioxide (also called dry ice), and comets have frozen ammonia and methane in addition to frozen water and other ices. Saturn's moon Titan is famous for its methane, which can exist as a solid, a liquid and a gas at Titan's surface temperatures and pressures.

What planets has ice at poles?
Like Earth, Mars has ice caps at its poles. Water reaches the poles as vapor and is frozen into thin layers that build up thick deposits. Mixed with this water is dust picked up by the wind, so the caps have bright and dark layers of "clean" and "dirty" ice.
What planets have ice on them?
There are two ice giants in the Solar System: Uranus and Neptune.
Which outer planets have ice?
The “ice giants” Uranus and Neptune are made primarily of heavier stuff, probably the next most abundant elements in the Sun – oxygen, carbon, nitrogen, and sulfur.
Which pole on Mars has ice?
south polar regionUsing this data, planetary scientists now know that the south polar region of Mars can be split into three separate parts. Part one is the bright polar cap itself, a mixture of 85% highly reflective carbon dioxide ice and 15% water ice.
Is there ice on Jupiter?
The gas planet likely has three distinct cloud layers in its "skies" that, taken together, span about 44 miles (71 kilometers). The top cloud is probably made of ammonia ice, while the middle layer is likely made of ammonium hydrosulfide crystals. The innermost layer may be made of water ice and vapor.
Is there ice on Venus?
The surface of Venus is the hottest in the solar system! Venus is too hot to have any type of ice on it. The surface of Venus is covered by its thick atmosphere of carbon dioxide.
Is there ice on Uranus?
Uranus is one of two ice giants in the outer solar system (the other is Neptune). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small rocky core.
Does Saturn have ice?
And because Saturn is very far away from the Sun, it is a very cold planet. That means the rocks in Saturn's rings are very icy. Some are even made entirely of ice, like snowballs. Saturn's rings are very bright because snow reflects sunlight strongly.
Does Pluto have ice?
NATIONAL HARBOR, MARYLAND—Researchers on NASA's New Horizons mission have discovered evidence on Pluto for what appears to be two cryovolcanoes—volcanoes built out of frozen ice that once oozed molten ice from the inside of the dwarf planet.
Does North Pole on Mars have ice?
Mars's north pole contains a large ice cap made up of many layers of frozen water. Like ice cores on Earth, those layers offer a tantalizing record of climate on Mars over the past several million years.
Is there ice on the moon?
The Moon's poles have permanently shadowed regions that never receive sunlight, where spacecraft have detected large amounts of water ice.
Does it rain on Mars?
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.
Is there ice on Uranus?
Uranus is one of two ice giants in the outer solar system (the other is Neptune). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small rocky core.
What planets have frozen water?
Uranus and Neptune are filled with "icy" materials like water, ammonia, and methane, under incredible heat and pressure. Some moons in the outer solar system have volcano-like geysers that erupt ice!
Does Pluto have ice?
NATIONAL HARBOR, MARYLAND—Researchers on NASA's New Horizons mission have discovered evidence on Pluto for what appears to be two cryovolcanoes—volcanoes built out of frozen ice that once oozed molten ice from the inside of the dwarf planet.
What is a frozen planet called?
An ice planet or icy planet is a type of planet with an icy surface of volatiles such as water, ammonia, and methane. Ice planets consist of a global cryosphere.
What type of ice is found in the solar system?
Image Token: . While the most common type of ice in our solar system is water ice, there are also many other types of ice. Mars'poles have abundant amounts of frozen carbon dioxide (also called dry ice), and comets have frozen ammonia and methane in addition to frozen water and other ices.
Which moons have ice?
Neptune's moons are also thought to contain large amounts of ice. Triton, Neptune's largest moon, is the only large moon in our solar system that orbits in the opposite direction of its planet's rotation -- a retrograde orbit. Triton is one of the coolest objects in our solar system; it is so cold that most of Triton's nitrogen atmosphere is condensed as frost, giving its surface an icy sheen that reflects 70 percent of the sunlight that hits it.
What are the features of the outer solar system?
Uranus and Neptune are filled with "icy" materials like water, ammonia, and methane, under incredible heat and pressure. Some moons in the outer solar system have volcano-like geysers that erupt ice!
What is the atmosphere of the Earth?
Earth: As Earth's surface cooled, water vapor in the early atmosphere condensed and precipitated, forming our oceans. Today Earth's atmosphere contains mostly nitrogen (78%), oxygen (21%), and minor quantities of other gases including carbon dioxide and water vapor. Our atmosphere has evolved; unlike Venus, a large amount of carbon dioxide has been removed from our atmosphere, dissolved in Earth's oceans, and precipitated as carbonate rocks. Over time, plants have contributed the oxygen through the process of photosynthesis.
How did the solar system form?
Instead, rocky materials and metals collected near the sun to form the smaller rocky planets. Farther out, beginning near the outer asteroid belt, ices were able to condense in the colder reaches of space, forming the cores of Jupiter, Saturn, Uranus, and Neptune-- the gas giants -- and their moons. Beyond the gas giants, the Kuiper belt and Oort cloud are host to the leftovers of solar system formation, small icy rocky bodies (yes, including Pluto!), and icy comets.
How did the Earth's atmosphere evolve?
As Earth, Venus, Mars, and Mercury evolved, they released gases from their interiors through volcanic activity. Volcanos on Earth continue to release gases today, including a lot of water vapor. On the early planets, these gases formed the planetary atmospheres. Atmospheres are important for maintaining relatively constant surface temperatures. On planets or moons without atmospheres that are close to the sun, the surfaces in sunlight get very hot and the surfaces in darkness (nightsides) get very cold.
Why does water evaporate on Mars?
Because of the low atmospheric pressures, liquid water at the surface of Mars would evaporate into water vapor. So what happened to all that water that used to be on the surface of Mars? Some did evaporate into space. But much is frozen under the surface and in the polar ice caps. Mars has water ice!
Where can you find ice?
On Earth, you can find ice in many places—for example, the North and South poles. But Earth isn’t the only icy world we know of. Ice can be found in many places in our solar system: on planets, moons, comets—and even in the rings of giant planets like Saturn. Click "Next" to learn more about a few of these cool places in our solar system!
Which moon has the coldest surface?
Neptune's largest moon, called Triton, has the coldest surface known in our solar system. As with all of the moons of Uranus and Neptune, it is made of ice and rock. Triton 's atmosphere is made up mainly of nitrogen. This nitrogen freezes onto its surface covering Triton with nitrogen ice. Triton also has geysers. On Earth, geysers spray fountains of hot water and steam into the air. On Triton , the geysers erupt with cold liquid nitrogen instead.
How many moons does Saturn have?
Saturn has more than 60 moons, all mostly made of water ice. Saturn’s moon Enceladus has a water-ice crust over a saltwater ocean. The ocean water on Enceladus sprays into space through cracks in the icy crust. All of this ice makes Enceladus one of the brightest objects in our solar system!
What are the chemicals in Uranus?
Uranus and Neptune both contain chemicals like methane, sulfur and ammonia in their atmospheres. 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."
What moon is Jupiter on?
An image of Jupiter’s moon Europa taken by NASA’s Galileo spacecraft.
What is the name of Jupiter's moon?
Europa is one of Jupiter’s many moons. Scientists think that Europa has a crust of water ice that floats on a saltwater ocean covering the entire moon.
What do the yellow spots on Mercury's image show?
The yellow spots in this image show the areas of Mercury that scientists think have water ice.
