Is there a planet in the universe that is full of water? What do you think?

Friends who have watched the American science fiction movie "Interstellar" know that there is a planet full of water in it, and the protagonist and others have to drive the spaceship away because of the huge waves set off here after landing on the planet.

So is there such a planet in the universe? It is likely that there is, but it can only appear that the surface is full of water, and it cannot be all water inside, because planetary planets are very massive, and the pressure inside is quite large, and even if there is water, it cannot exist in the form of liquid water.

Our earth looks like a water ball from outer space, especially when you look at the Pacific Ocean, you can hardly see the land, the whole is a round water ball, this is because most of the earth's surface is liquid water, accounting for 71% of the entire earth, but there is still a lot of land on the earth, and these oceans are all land.

If you count in terms of volume, the water on the whole earth is actually very little, the diameter of the earth is more than 12,700 kilometers, the average depth of the earth's ocean is only about 4,000 meters, if the earth is regarded as a big ball of one meter, then the depth of the ocean is only four millimeters, do you feel that it is pitiful?

And if all the water on the earth is gathered into a sphere, the diameter of this sphere is only about 800 kilometers, which is far from the volume of the earth, and if the diameter of this water ball is more than 1000 kilometers, then if the horizontal spread to the earth, we basically can't see the land, and the earth will become the appearance of the water ball in "Interstellar", but even so, the volume of water on the earth is still far from the whole earth, and it cannot be called a water ball.

However, from astronomical observations, water is widespread in the universe, and in our solar system, outside the middle of the asteroid belt, most celestial bodies contain large amounts of water, such as Ganymede.

1. Ganymede. 2. Ganymede.

3. Encete. Sixth, Triton and so on, these large satellites contain much more water than the Earth.

For example, Io has twice as much water as Earth, Io.

3. Ganymede. 4. Planets such as Titan have ten times more water than the Earth, but these stars are much smaller than the Earth, and they are not much different from the size of the Moon. If all the water on them melts without losing mass, then they look like complete balloons, and they can reach depths of 100 to 200 kilometers, which is much deeper than the oceans on Earth.

Personally, I think there may be planets in the universe that are full of water. After all, the universe is very large, and human beings have not explored the complete universe. Anything is possible. And there are many planets with more water than Earth's. So it's possible that there will be a planet full of water.

The planet is Europa of the solar system, Europa's sixth moon, with an atmosphere rich in oxygen and a 100-kilometer-thick layer of ice below the ocean. Europa is a planet full of water.

Personally, I think there is, because the world is so big that there are no wonders, but now our human science has not confirmed this, so we can't speculate arbitrarily.

The planet with water in the universe: Enceladus.

Sixth, Ganymede. 2. Ganymede.

4. Earth, Mercury, etc.

1. Titan.

Titan, also known as Titan, is a moon orbiting Saturn, the largest of Saturn's moons and the second largest in the solar system. It was discovered by Dutch physicist, astronomer and mathematician Christian Huygens on March 25, 1655, the first moon to be discovered in the solar system after Jupiter's Galilean moon.

Because it is the only moon in the solar system that has or is late to the thick atmosphere, it is highly suspected of the existence of life, and scientists have speculated that methane in the atmosphere may be the basis for life.

2. Europa.

Europa [ju r up], discovered by Galileo in 1610, is the sixth known moon of Jupiter, the fourth largest of Jupiter, and the second closest to Jupiter among the moons discovered by Galileo.

3. Callisto.

Callisto, also known as Calisto (English pronunciation: k l sto, Greek: is a moon orbiting Jupiter, first discovered by Galileo Galilei in 1610.

Europa is the third largest moon in the Sun's Huna system and the second largest moon of Jupiter, after Ganymede.

4. Earth. Earth is one of the eight planets in the solar system, the third planet in order from near to far, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun. The Earth rotates from west to east while revolving around the Sun.

It's 4,04.6 billion years old, and it has a natural satellite, the Moon, and the two make up a celestial system, the Earth-Moon System. It originated from the primordial solar nebula 4.6 billion years ago.

5. Mercury. Mercury is the innermost and smallest of the eight planets in the solar system, and it is also the closest planet to the Sun. China, known as Chenxing, has the largest orbital heart rate among the eight planets.

It orbits the Sun once every Earth day, and it also rotates three times per revolution.
