What Are Planets With Water?

Earth is the only planet in the Solar System with liquid water on its surface. All other planets would immediately freeze or evaporate if they had any liquid water. However, several places in the Solar System may contain liquid water underground. Water exists on a number of planets in different states, such as the ice-covered planets of Jupiter, Saturn, Ceres, and Enceladus. Some of these planets may also contain liquid water underground, including exoplanets and dwarf planets.

Earth’s Moon

The Moon is the only natural satellite of Earth and it measures about one-fourth the diameter of the Earth. The moon is the fifth largest satellite in the Solar System, larger than any dwarf planet. It is a planetary mass object, and unlike Earth, has no atmosphere, hydrosphere, or magnetic field. The surface gravity of the Moon is approximately one-sixth that of Earth. The Earth has a much lower gravity than the Moon, which makes the Moon appear much larger than it really is.

Earth is the only planet in the solar system with liquid water at its surface. Its liquid water is available in lakes and oceans and in solid form as ice caps and glaciers. Earth’s Moon is also thought to have liquid water below the surface, as it contains small amounts of water ice in permanently shadowed craters. There are also some buried ice deposits on the poles of the moon.

Recent research has revealed that the moon is much wetter than previously thought. Although liquid water is not possible to stay on the Moon’s surface, scientists have discovered increasing amounts of water ice. Researchers believe that water is trapped inside minerals deep within the orb. Ancient volcanic glass beads have also revealed evidence of water ice. The presence of water on the Moon would not only help future human missions but could also provide valuable information about earlier conditions in the Earth-Moon system.


Did you know that Jupiter is a planet with water? Scientists recently reported that the moon Europa may contain water that we can’t detect. This finding would be exciting for scientists, who have been hoping to find life beyond Earth’s icy surface. The water that Europa is suspected of possessing comes from its collision with comets early in its history. Jupiter is also believed to have a liquid ocean beneath its surface.

The planet’s bright colors are likely plumes of sulfur-containing gases rising from its interior. Because of its fast rotation, Jupiter has thick clouds that separate into bright and dark zones. While this makes the planet appear more colorful, it does not have a lot of water. Its dense atmosphere may also be responsible for its intense storms and bright spots. Regardless of its origins, scientists continue to research the planet’s fascinating surface.

If Jupiter were a planet, its atmosphere would have more oxygen than the Sun, because oxygen would combine with the abundant hydrogen in the Jovian atmosphere. But recent spacecraft discoveries indicate that the atmosphere of Jupiter does not contain as much oxygen as expected. In addition, water is only a trace element in Jupiter’s atmosphere. However, scientists will continue to search for signs of water on Jupiter to better understand its climate and other features.


The surface of Saturn is composed primarily of gas and is therefore less dense than water, making it possible to float on it. While other planets have much higher densities, Saturn’s is the lowest, making it far lighter than its counterparts. Saturn is also much more rocky than its cousins, making it an excellent candidate for colonization by humans. The largest known moon of Saturn is Titan. During the 1990s, a light-coloured storm system appeared on Saturn’s surface. It spread across the planet’s equator and then faded.

The density of Saturn is the lowest of all the planets in our solar system. If it were a ball, it would be the same density as water. Compared to water, Saturn’s atmosphere is less dense than that of Jupiter. Its hazy yellow clouds are crystallized ammonia. The easterly winds on Saturn reach speeds of over 1,100 miles per hour on its equator and up to 1,770 kilometers per hour at its poles. Saturn has a similar interior structure to Jupiter, though its atmosphere contains less helium than Jupiter. The lower concentration of helium on Saturn also contributes to its colder temperature.

The presence of water on Saturn has been discovered through the Cassini mission. Using the VIMS instrument, scientists have discovered that the water in Saturn’s system is similar to terrestrial water. However, it is not water as we know it on Earth. One of the most fascinating aspects of this discovery is that Saturn has a unique moon, Phoebe. The moon’s water probably formed in a solar nebula.


In addition to the possibility that there’s liquid water on Enceladus, the icy planet also has an energy source and organic molecules. Geysers on Enceladus likely originated from a regional sea below. Its subsurface sea could stay warm for billions of years. The tidal forces on Enceladus may keep the subsurface water warm. Whether or not this water is habitable depends on the chemistry of its composition.

In 2005, the NASA Cassini spacecraft revealed active water plumes on Enceladus. The UVIS instrument determined that there was water vapor above the limb of Enceladus’ South Pole. Similar UV occultations did not reveal any gaseous species, however. The scientists were able to identify jets of water from fractures in Enceladus’ surface, proving that the moon likely has water.

The Cassini spacecraft captured the image of Enceladus on Nov. 30, 2010. The plume is composed of a mix of gases including water vapor, carbon dioxide, methane, and nitrogen gas. The plume is surrounded by a gaseous envelope of water vapor, carbon dioxide, carbon monoxide, silica, and nitrogen gas. The scientists found that organic material was 20 times more dense than expected.

Although the moons of Saturn have abundant water ice, some scientists think that they may contain a liquid ocean underneath. Cassini has detected geysers of water vapor at the moon’s southern pole. The presence of liquid water on Enceladus has led to theories that a liquid ocean may be lurking underneath Saturn’s ice-covered planet. This is not the first evidence that water exists on Enceladus.


Scientists have long suspected that Pluto is a planet with water. They assume that the ocean on Pluto has a ‘cold start’, meaning it formed when the dwarf planet was frozen. As the icy core melted and refroze, the ocean would have expanded and contracted, leaving the planet with cracks and craters. Pluto may have been formed this way, but it is still unknown how it got there.

The icy surface of Pluto appears smooth from above, but when viewed in a closer angle, it is full of mountain ranges and valleys. Other types of ices on Pluto are less stable and are more sensitive to sunlight. The latter play the role of snow on Pluto, covering the landscape in winter. Pluto is also a possible home to life forms, including two ice-capped volcanoes. Despite its icy appearance, Pluto’s water ice is more abundant than originally thought.

In 2015, NASA’s New Horizons spacecraft flew past Pluto, revealing active and complex surface geology. It also raised the suspicion of an ocean beneath Pluto’s crust. Several planetary scientists now agree that Pluto does have an ocean, and that it likely had one at some point in its history. As a result, the discovery of water beneath Pluto’s surface could help scientists understand how other planets may have similar bodies of water.


NASA’s Dawn mission has uncovered evidence that the dwarf planet Ceres has liquid water under its icy crust. The scientists discovered brines percolating up to the surface. They believe that the water ice in these pockets may be remnants of a previous water ocean on Ceres. The icy dwarf planet Ceres is similar to Earth’s icy moons. The research is published in Nature.

The study aims to test the theory that Ceres has water because of its proximity to Earth. The team has used spectral data from Dawn to analyze the surface of Ceres. The surface of Ceres appears to be composed mostly of silicate minerals and large amounts of ammonia. Ammonia is a typical cometary material that is only stable in the outer solar system. Alternatively, Ceres may have formed in a much further reaches of the solar system and later moved into the asteroid belt.

Despite the aforementioned evidence, scientists are still skeptical about Ceres’ water reserves. While the surface water of Ceres isn’t enough to support the notion of an ocean beneath the planet’s crust, it may indicate a smaller reservoir beneath its surface. Nevertheless, the presence of an ocean or a brine on Ceres could be indicative of life. Moreover, the presence of organic matter on Ceres’ surface may indicate the existence of similar chemical reactions on Earth before the formation of life.
