No, a planet cannot be 100 percent water. The Earth is mostly covered in water, but only approximately 71% of the surface of the Earth is covered in water. For a planet to be completely made of water, it would need to be much larger than an Earth-sized planet, as the lack of land mass would mean that the gravity required to keep the planet in an Earth-like atmosphere would be much higher than on Earth.
Additionally, it would be difficult for a planet to hold in an atmosphere made entirely of water. Water acts as a strong greenhouse gas, so if the atmospheric pressure were high enough to contain the planet’s heat, the atmosphere would become too hot to sustain life.

Is there a planet completely made of water?
No, there is no planet known to be made of solely water. A terrestrial planet, such as Earth, is made up of solid ground, liquids, such as water and gases, such as air. A gaseous planet, such as Jupiter, is made up primarily of gases, such as hydrogen and helium, with some liquid metallic hydrogen at its core.
According to current theories, a terrestrial planet must also have some sort of geologic activity to keep its crust liquid and mixed. A planet made of water would need to be constantly heated by a large star or nearby planetary object in order to keep it liquid and mixed throughout, and no such planet has yet been found.
Did NASA find a water planet?
NASA discovered an exoplanet in a star system about 8,000 light-years away from Earth. It is the first exoplanet that researchers have found that has all the ingredients for potentially supporting life – a rocky surface, along with water (in liquid form).
The research team studied two stars in the Kepler-88 system, both of which are much hotter than the Sun. The exoplanet is thought to be located in the “habitable zone” – the orbital region where temperatures could also support liquid water.
The exoplanet is approximately 40% larger than Earth and is the smallest exoplanet found in Kepler-88 so far.
The discovery of the water planet has been very exciting for the scientists, and this may be the first of many planets to be found in the system. NASA will continue to study the exoplanet, and they are hopeful that they may encounter other planets capable of hosting life in the near future.
At this time, the team can only say that the exoplanet is potentially habitable, as much more research and observation must be done before an official confirmation can be made.
Did James Webb find a planet with water?
No, James Webb did not find a planet with water. James Webb is a space telescope that was launched in October of 2018 and is still in operation today. Its mission is to study stars, galaxies, and planets to gain a better understanding of the universe.
It has a variety of scientific instruments which provide detailed images of distant cosmic objects. While it has allowed us to study many different planets, it has not yet detected any planets with water vapor.
The spacecraft has observed signs of water vapor clouds in various regions ot he universe and has also detected water vapor in the atmosphere of many exoplanets. However, researchers have not yet been able to confirm whether this water originated from the planet itself or from a satellite or nearby comet.
What is diamond planet?
A diamond planet is a hypothetical type of planet composed of solid diamond. Such a planet would be extremely rare, since diamond is rare on Earth– not only are diamonds extremely rare, but the conditions needed to form them (high temperatures and pressures) don’t typically exist anywhere else in the universe besides in a very small area of a few millionths of a millimeter deep inside the Earth’s mantle.
Potential diamond planets have been theorized to possibly exist around some of the smallest and coldest white dwarfs. White dwarfs are formed when a star runs out of fuel and is no longer able to sustain nuclear fusion reactions in its core.
This causes them to cool and contract until nearly all of their mass is concentrated into a volume about the size of Earth (about the size of a small city). At their density, white dwarfs are thought to be able to support temperatures and pressures high enough to create and sustain diamond planets.
Unfortunately, due to the rarity of such planets, we haven’t yet been able to observe or detect any diamond planets. However, scientists continue to study white dwarfs in the hopes of finding a diamond planet one day.
Is there a pink planet?
No, there are no pink planets in our Solar System. However, some planets, such as Venus and Mars, can appear pink due to the illumination of their respective atmospheres. Furthermore, certain stars can appear pink due to the chemical compositions of their atmospheres.
For example, the star Betelgeuse, in the constellation of Orion, can often appear pink instead of its typical red hue. So, although there are no pink planets in our Solar System, certain stars and planets can have a pinkish hue.
What planet has most water?
Earth is the planet with the most water. Nearly 71% of the planet’s surface is covered with water, and the oceans contain about 96. 5% of all Earth’s water. Similar to land, the water exists in different forms including liquid, solid, and gas.
The water cycle helps to replenish the Earth with new water and maintain the water supply. Water is often referred to as the Earth’s Lifeblood and helps support all life on the planet.
Which planet is 70% covered with water?
The planet Earth is estimated to be 70% covered with water. This includes all oceans, large lakes, and smaller bodies of water like rivers, streams, and marshes. Of the 70% water coverage, about 97% is salt water and just 3% is freshwater.
Over two-thirds of the planet’s freshwater is frozen in the solid form of glaciers, icebergs, snow, and soil moisture. The remaining 1% of liquid freshwater is spread over the ground and stored in aquifers and other underground geologic formations.
Such a small percentage of freshwater is essential for the survival of the human race, as well as all other life on Earth.
What is 70% of the earth’s surface covered with?
Approximately 70% of the earth’s surface is covered with water. This is primarily due to our planet’s high surface temperatures, which causes much of the water to be in liquid form. This water can be found in sources such as oceans, lakes, rivers, and groundwater.
A small portion of the earth’s surface is also covered in ice and snow. In addition to water, land takes up approximately 30% of the earth’s surface. This land is comprised of deserts, mountains, plains, and forests, among other types of terrain.
Finally, a tiny portion of the earth’s surface is occupied by human-made features such as roads and buildings.
Does the ocean cover 75% of the world?
No, the ocean does not cover 75% of the world. Although the ocean covers approximately 70% of the surface of the Earth, the other 30% is made up of land mass, including the continents and islands. The ocean is vast, covering about 360 million square kilometers, but it only makes up roughly two-thirds of the Earth’s surface.
The other 33% of our planet’s surface is made up of the landmasses we identify as the continents, islands, mountain ranges and other geographical features. The total area of land mass on the Earth is approximately 149 million square kilometers.
What is the third planet from the sun and is covered by 75% water?
The third planet from the sun is Earth, and it is covered by 75% water. There are five major oceans on Earth: the Atlantic, Pacific, Indian, Arctic and Southern Oceans. Together, these oceans have an average depth of 2.
3 miles and cover more than 140 million square miles, or more than 70% of the planet’s surface. The world’s rivers, lakes, reservoirs, and underground aquifers make up the remaining 5% of the water on Earth.
The vast majority of the world’s water is found in the oceans, with the Pacific Ocean containing about 46% of the total and the Atlantic Ocean containing about 22%.
What would a water planet be like?
A water planet would be a fascinating and unique place. It would have few solid land masses, with most of the world made up of oceans of water. The atmosphere would be thick and humid, filled with clouds, steam, and sea spray.
The temperature would be comfortably warm and tropical, but could also be colder in deep ocean trenches.
The oceans of a water planet would be home to a plethora of different aquatic creatures, some species of which yet to be discovered. The sea would be full of reefs, hydrothermal vents, and a variety of organisms of all sizes and colors.
It is likely that any lifeforms on the planet would evolve to take advantage of the rich aquatic environment and develop adaptations such as gills or fins.
The landscape of a water planet would be ever changing as tides and currents ebb and flow. There would also be a heavy concentration of storms and turbulent weather, as well as times of great stillness.
The moon, planets, and stars would be visible from the surface of the water, giving the planet an ethereal, otherworldly beauty.
In summary, a water planet would be a thriving, aquatic paradise teeming with life. It would be a wondrous place to explore and marvel at the diverse aquatic ecosystem that thrives beneath its waves.
What would the Earth look like if all the water was gone?
Without water, the Earth would look vastly different. Without water, the Earth would be much parched and barren. Mountain ranges and coastlines would be much different as there would no longer be large bodies of water to form their landscapes.
Forests and swamps would be nonexistent without water, leaving deserts and grasslands in their place. Plant and animal life would be drastically different; many animals would not survive the lack of water and foliage, and those that could would not thrive.
Without water, the atmosphere would be much drier and harsher; temperatures would be three times higher and the air would be filled with dust and particles, resulting in permanent smog. Cloudless skies would be a common sight as the evaporation cycles needed to form clouds would be disrupted.
Many cities established near bodies of water would become uninhabitable as resources, such as food and water, would be scarce. Life on Earth would struggle to exist in the face of such a drastic change.
Could a planet have a water core?
In theory, a planet could have a water core. In practice, however, that is unlikely to be the case. Though there is some evidence that at least some of the giant planets in the solar system may have a small water-rich core, this core is believed to be relatively insignificant compared to the layers of rock and ice surrounding it.
In other words, the core of the planet is mostly composed of other materials, not water.
It is also unlikely that a terrestrial planet (like Earth for example) has a water core. The density of a water core combined with the complexity of the physics involved in such a structure would make it very hard for a terrestrial planet to form in the first place.
The best way to tell whether a planet has a water core is to look at its chemical composition. Water has a distinct chemical signature that can be detected in the observable properties of a planet. If a planet is found to have an abundance of water, then it may be a possible indication of a water core.
Why can’t we just create water?
Creating water from its base elements, hydrogen and oxygen, is not possible in a spontaneous way. In order for water to be created there needs to be an activation energy, or an external source of energy, to break apart the hydrogen and oxygen molecules and form two single-atom particles of hydrogen and oxygen.
These single atoms can then form a stable compound of water, which requires a much higher energy than photochemical reactions in the Earth’s atmosphere can provide. Therefore, while water can theoretically be created, it requires an external energy source and is far too energy intensive and costly to produce on a large scale.
