The planet that has no known water is Mercury. Mercury is the smallest and innermost planet in the Solar System, orbiting the Sun once every 87. 97 Earth days. It is one of the four terrestrial planets, and it has no known natural satellites.
Mercury is labeled as a “terrestrial” planet due to its dense, rocky composition. The surface of Mercury is heavily cratered and characterized by numerous cliffs and ridges. It has a very thin atmosphere composed primarily of helium and traces of other gases, including oxygen, carbon dioxide, and sodium.
Mercury has a solid core which is approximately 1,700 km in radius and makes up 60% of the planet’s total radius. Scientists theorize that the core is primarily composed of iron and nickel, surrounded by a mantle of silicate rocks.
Mercury’s extreme temperatures — ranging from -173 to 427 degrees Celsius (-279 to 800 degrees Fahrenheit) — make it one of the least hospitable bodies in the Solar System. These extreme temperatures, combined with the lack of a significant atmosphere, suggest that water does not exist in any form on the planet.
Therefore, Mercury is considered to be a desert world with no known water.

In which planet there is no air?
All planets in our solar system, including Earth, have some form of atmosphere, even if it is just trace gasses. In Earth’s case, the atmosphere is comprised of nitrogen (78%), oxygen (21%), argon (.
9%), carbon dioxide (. 04%), and other trace gasses. The atmospheres of other planets may vary greatly, but all of them contain some form of air.
Is there no water in other planets?
No, there is no confirmed evidence to suggest that there is any water on other planets. While some scientists have hypothesized that other planets may have underground reservoirs of water or ice, there has been no definitive proof.
Additionally, even if water exists on other planets, it is likely to be in a form that is not suitable for sustaining life. For example, on Mars, most of the water is likely to be frozen in the soil and atmosphere.
Scientists believe that the surface water on Mars is more likely to be salty brines rather than liquid fresh water. Overall, it is still an open question as to whether there is water on other planets, but there is no concrete evidence that suggests it is the case.
Are there any planets with air?
No, there are currently no planets that have air like Earth. Although the atmospheres on other planets in the solar system may be composed of certain gases, the air on those planets cannot sustain life like the air on Earth.
Some of the planets may have atmospheres that contain nitrogen, oxygen, carbon dioxide, methane, water vapor and trace amounts of other gases, but the air on planets like Jupiter and Uranus has too much or too little of these gases to be breathed by humans.
Moreover, temperatures on many of these planets may be too cold or too hot to sustain human life. Despite the harsh conditions on other planets, there is hope that one day humans may be able to live on another planet.
Scientists are currently working on technology to help us colonize Mars and establish a livable atmosphere there.
Does Pluto have water?
Yes, Pluto does have water. There is evidence that Pluto has a subterranean layer of liquid water ocean beneath its icy surface. Scientists believe that data from the New Horizons probe in 2015, which flew past Pluto, indicated that this is the case.
Further analysis of the data, especially close-up photos taken during the flyby, showed surprising differences in the profile of Pluto’s surface compared to other icy celestial objects in our Solar System.
The most likely explanation is that Pluto has a layer of liquid water beneath its icy surface. This would explain why the frozen nitrogen and snow on the surface are patchy and uneven. Additionally, chemical analysis of the New Horizons probe revealed signs of chemically bound water (or “bound water”) on the surface of Pluto.
This chemical evidence contradicts the idea that Pluto never had any liquid water, instead supporting the idea of an underground ocean.
Did Mars ever had water?
Yes, Mars at one point in its history had water. Signs of ancient water on Mars have been discovered by the Mars exploration rovers Opportunity and Spirit, and the Mars Reconnaissance Orbiter among other missions.
Signs of ancient water can be found in the form of rocks and soils with minerals that could only form in the presence of water, as well as layered sedimentary deposits, shoreline-like features, and minerals such as carbonates, clays, and sulfates.
The Mars rovers have also discovered evidence of surface water in the form of valleys that have been carved by water and channels from run-off. From these discoveries, it is believed that at one point in its history, Mars was a wetter and possibly warmer world than it is today.
What did NASA find in the ocean?
NASA has discovered a wide variety of interesting things from the depths of the ocean. In 2016, they discovered thermal vents near the Mid-Cayman Rise, the deepest point in the Caribbean Sea. In these vents, they found highly acidic water, new species of bacteria and archaea, iron-reducing bacteria, iron-oxidizing bacteria, and single-celled organisms with an entirely novel metabolic process.
In 2017, there was a robotic mission to explore an underwater mountain range in the Pacific Ocean. The mission retrieved samples of sediment and water revealing a variety of living organisms adapted to the extreme environment of the deep sea.
These organisms included bacteria that could produce methane, with potential implications for the way carbon cycles through the Earth.
In 2018, the mission documented the existence of methane-eating bacteria living on the ocean floor in extreme cold temperatures. The discovery increases our understanding of life on the seafloor, and suggests the existence of a bacterial food web that is largely unexplored.
In 2019, the mission set off to explore the Atlantic Ocean and recovered pictures of about fifteen previously unknown species of fish and shrimp, along with rich microbial communities. The mission also uncovered a chemical balance that suggested an interaction between the water, nutrients, and the sediment on the ocean floor.
These findings demonstrate the tremendous potential of the ocean and give us insight into the unseen parts of our world. NASA has revealed many new discoveries that have helped us better understand the complexities of the ocean, which is essential for preserving our fragile marine ecosystems.
What planet has air like Earth?
Earth is the only planet in the Solar System known to have an atmosphere containing oxygen and nitrogen similar to the air on Earth. This is due to the unique combination of abundant elements and biological activity over Earth’s history, which has produced an atmosphere that is stable and hospitable to life, and which has shielded the planet from extreme temperature changes, harmful radiation, and meteorite impacts.
Earth’s atmosphere consists of 78% nitrogen, 21% oxygen, and other trace gases, including argon, carbon dioxide, and water vapor. Over the past 4. 5 billion years, Earth’s atmosphere has been gradually modified and sustained by the process of photosynthesis and the Earth’s carbon cycle.
Photosynthesis, which is performed by plants and algae, converts sunlight into energy, which is then passed along to higher levels of the food chain and eventually to humans. In addition to supplying Earth’s surface with oxygen and providing us with food, photosynthesis also produces oxygen and captures carbon from the atmosphere and locks it up in plants.
This process has been essential in removing carbon compounds from the atmosphere and keeping the atmosphere relatively consistent over time.
How many planets do have oxygen?
There are currently eight planets in our solar system that have oxygen present in their atmosphere: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Oxygen is one of the most common substances in the solar system, with Earth having the highest concentration of oxygen.
Venus and Mars have much lower concentrations of oxygen in their atmospheres, with trace amounts present on Jupiter, Saturn, Uranus, and Neptune.
Oxygen is believed to have come about through a process known as photolysis, in which ultraviolet light from the Sun breaks down molecules like carbon dioxide and water into their component parts, releasing the oxygen atoms.
Once released, these oxygen atoms become part of the atmosphere on the planets. Over time, Earth’s oceans and atmosphere grew more and more oxygenated, eventually reaching the level of oxygen in the atmosphere we see today.
It is believed that all of the rocky planets in our solar system have oxygen in their atmospheres and likely formed oxygen in a similar way. However, more research is needed to confirm this. Additionally, it is possible that other bodies in the solar system including moons, asteroids, and other dwarf planets may also contain oxygen, though this has yet to be confirmed.
Is Jupiter wet or dry?
Jupiter is a gas giant, so obviously it is not made of liquid water like Earth is! However, it is believed to have a wet interior due to the detection of water vapor in its atmosphere. This suggests that Jupiter could contain a massive ocean beneath its cloudy exterior.
Further evidence of this comes from the discovery of lightning and ammonia clouds in the atmosphere of Jupiter. These features are typically associated with precipitation in other planets and atmospheres.
Therefore, while Jupiter is not actually wet, its atmosphere is believed to contain a lot of water vapor and potentially a vast ocean beneath the clouds.
Can you drink the water on Jupiter?
No, it is not possible to drink the water on Jupiter. Jupiter is a gas giant with no solid surface, so there is no accessible water on the planet. In addition, any water found in the atmosphere of Jupiter is composed of hydrogen and oxygen atoms and is in the form of water vapor.
Therefore, it is not possible to drink the water on Jupiter.
Can water exist in space?
Yes, water can exist in space. In fact, it is estimated that roughly 80 percent of the visible universe is made up of gas and dust, which is mostly composed of water molecules. Even in the areas of space that don’t contain a lot of water vapor, such as the vast regions of intergalactic space, water can still be found.
It is commonly found in the form of ice, in the form of comets, asteroids, or moons. Astronomers have even discovered entire galaxies that are composed of mostly water vapor! Thus, water does indeed exist in space, though it is rare and typically in a molecular or icy form.
