How scary is Pluto? It was kicked out of the ranks of the stars for a reason

Pluto is only one-third the size of the Moon, and weighs 470 times lighter than Earth, in addition to the discovery of Eris in 2015, the planet is about 27 heavier than Pluto, so in 2016, IAU (the abbreviation of the International Astronomical Union) officially defined the concept of planets, excluding Pluto from the planetary range and classifying it as a dwarf planet (Pluto-like body).

He is one of many dwarf planets. The outer Kuiper Belt of the Solar System is a ring of dwarf planets of all sizes and sizes that resemble Pluto, so it is excluded from the list of planets.

It's not that it's scary, it's that it's so small that it resembles many asteroids in the solar system, so it was removed.

Pluto, kicked out of the nine planets, it's not terrible. Judging by Pluto's name, we can feel the awe it felt at this celestial body when it was discovered. Its name is the god of death who rules the region of Roman mythology. Of course, the translation is our Hades, which is also related to hell.

After Pluto was discovered, the more scientists looked into it, the more strange it became. Because it is very different from other planets, it mainly has the following aspects. It's too far away.

Pluto orbits the Sun in a special elliptical orbit with a period of 248 Earth years. The closest and farthest distance to the Sun is and (AU is the astronomical unit, the average distance from the Earth to the Sun). Pluto is closest to the Sun, even closer to the Sun than Neptune.

The track inclination angle is large. The other eight planets of the solar system revolve around the Sun in the same plane (the ecliptic plane), but unlike Pluto, Pluto's orbit reaches 17 degrees on the ecliptic plane. If Pluto is not found to be close to the ecliptic plane, Pluto may still be a few years away.

The temperature is very low. Because it is so far from the Sun, it takes 5 hours for the sun's rays to hit Pluto's surface. As a result, Pluto's surface is very cold between minus 238 and 218 degrees Celsius.

The nitrogen, carbon monoxide, methane, etc. on Pluto's surface freeze into solids, and the white ice turns pinkish-brown under the action of the deep space kiln line and the sun's light. If a human is in it, the body freezes instantly.

In fact, in the 80s of the 20th century, scientists doubted that Pluto was not a cold edge of the solar system. Later in 1992, the Kuiper Belt was discovered and proven by astronomical telescopes in Hawaii. Since then, 1,500 Kuiper Belt objects have been discovered.

More scientists estimate that there are about 100,000 objects with diameters of more than 100 kilometers throughout the Kuiper Belt. As a result, more and more people are questioning Pluto's status as the "ninth planet". By January 2005, Mike Brown's team had discovered Eris, the goddess of Greek mythology, Eris, the size of Pluto and a mass far greater than Pluto.

The hairstyle of the nova became the trigger for Pluto to be expelled from the 9 planets.

In fact, Pluto is not scary in the solar system, and in some ways it is no scarier than Jupiter. But this fear of Pluto is beyond the knowledge of scientists and people's imagination, so I think it is mysterious and terrifying. Of course, much of the current research on Pluto is superficial.

I think it's really scary, because scientists are still investigating it, and Pluto's ** is also very scary, so I think it's really scary.

No, Pluto is not that scary, because this planet is special, it is very cold on it, and the gas is relatively thin, so it is very special.

I don't think it's scary, it's just a sphere, there's nothing scary about it.

Pluto was kicked out of the nine planets, and its surface temperature is extremely low and the environmental conditions are not good. Pluto, English name is Pluto, is a planet named after the god of death, Pluto is the god of hell in Roman mythology, that is, the god of death, and Hades, the king of Hades in Greek mythology.

Because it is difficult for the sun's light to reach it, Pluto has been in a dark and cold world, and there are several reasons why Pluto was removed. The first point is that Pluto is so small, smaller than the Earth, the Earth's moon, and of course, scientists don't look down on it because it's short. The main reason is that Pluto has an asteroid in orbit that is even more massive than it, and if Pluto is a planet, then wouldn't its moon (possibly a companion) be the tenth planet in the solar system? So, given that Pluto has asteroids in orbit that are more massive than it, Pluto has been removed from the list of planets. Pluto is very far from the Sun, it is about 40 times the distance from the Earth from the Sun, so there is very little sunlight that can reach Pluto, and the average temperature on the surface of Pluto is minus 230 degrees Celsius, which can be described as a bitter cold place. This is nothing, because the temperature is too low, so Pluto has almost no atmosphere, the surface is all icebergs, mainly solid nitrogen and a small amount of methane and carbon monoxide, oxygen does not need to be thought, even if there is it will be frozen into ice because Pluto is too far away from the sun, so its orbital period has reached 248 years, so that the polar day and polar night on Pluto will be particularly long, some places are rare to see the sun for hundreds of years, and some places have no night for hundreds of years. Pluto is mostly made of rocks, and there may be liquid water between the Earth's core and mantle, but it is not easy to obtain it, and even with that much liquid water, the likelihood of life is almost zero. And due to the extremely low temperature on the surface of Pluto, it is not possible for humans to send a probe to detect Pluto, because it is difficult for the machine to operate normally.

Pluto is too far away from the sun, its temperature is super low, the average surface temperature is only minus 230 degrees, and its surface is solid nitrogen with a small amount of methane, and many methane icebergs exist inside**!

It's scary. Because the temperature above Pluto is very low, and the natural environment is very harsh, it is very scary.

Pluto is destined for very low temperatures. The average temperature on its surface is only about minus 230 degrees.

Not only that, but what is even more terrifying is that more than 98% of Pluto's surface is made up of solid nitrogen, as well as a small amount of methane and an extremely small amount of carbon monoxide.

American astronomer Clyde Tombaugh discovered Pluto and named it the ninth planet, and since then, the solar system has been nine planets for a long time. It was not until the 26th International Astronomical Union in 2006 that Pluto was classified as a dwarf planet and officially removed from the list of planets, the solar system has also become eight planets. This caused quite a stir at the time, and many people even said that they could not accept this result.

What the hell is going on?

In fact, from the name of Pluto, we can feel the awe of this celestial body when it was discovered, its name is the Roman mythology of the god of death (pluto), of course, translated as our Hades, also related to hell. Since this celestial body is very far away from us, outside the orbit of Neptune, it is on average 6 billion kilometers from EarthEven when humans first discovered the existence of this celestial body, it was full of unknowns because the image of it was very vague.

In addition to the mystery brought by the unknown, before Pluto was discovered, the astronomical community had been searching for the mysterious Planet X for 30 years. Therefore, after the discovery of Pluto, people were shocked, and it can be said that it caused a sensation in the entire scientific community. This is also why Pluto was so profoundly publicized and popularized at that time, and basically everyone knew that mankind had discovered the ninth planet.

Dwarf planets and planets are also celestial bodies that do not emit light on their own, orbit the host star, and are massive enough to form a near-spherical shape. By definition, there is not much difference from the traditional meaning of "planet", and dwarf planets are also called "dwarf planets". So it is difficult to distinguish whether a celestial body is a planet or a dwarf planet.

Therefore, it is important to redefine the definition of planets and dwarf planets, otherwise it may be messed up.

So, at the International Astronomical Union Congress on August 24, 2006, astronomers redefined the requirements for planets, which must be celestial bodies orbiting the host starIn addition to being massive enough to maintain a near-spherical shape, it must also be able to clear the area near the track, there can be no larger celestial body within the orbital range. According to the new definition, Pluto meets the first two requirements, and the last one does not meet Pluto. So Pluto was kicked out of the list of planets.

Pluto is only one-third the size of the MoonIt is also 470 times lighter than Earth, in addition to the discovery of Eris by astronomers in 2015The planet weighs about 27 more than Pluto, so in 2016, IAU (short for International Astronomical Union) officially defined the concept of planets, excluding Pluto from the planetary range and classifying it as a dwarf planet (Pluto-like object).

It is particularly terrifying, the temperature of this planet is particularly low, the lowest can reach more than minus 200 degrees, and the atmosphere above is particularly thin.

It's terrifying, Pluto's environment is harsh, and Pluto's ability to rotate is very fast.

It's very scary, and I can see that it's going to have a big impact, and it's going to have a lot of changes.

Pluto is not wronged in kicking the planetary industryPluto is a planet in the solar system, once located in one of the eight planets, but later, as humans observed Pluto more and more carefully, they finally kicked Pluto out of the eight planets, but this does not prevent Pluto from being a very mysterious planet; Pluto is located at the edge of the solar system, because it is too far away from the solar system, so it is frozen all year round, and people can see through astronomical telescopes that there is a huge heart-shaped pattern on the surface of Pluto, and it was once believed that Pluto was very large; However, after more detailed observations, it was found that Pluto's volumetric mass was far from the standard of the other eight planets, so Pluto was kicked out of the eight planets. <>

Pluto is very mysteriousBecause Pluto is very far away from the Sun, there is not much heat left when the sun's light hits Pluto, which also causes Pluto to be a frozen world; There is an atmosphere in Pluto's atmosphere, but because the temperature is so low, even the gas freezes and falls on the surface of Pluto. At the same time, some scientists speculate that there is very likely to be life on Pluto, that is, a virus, so many people also call Pluto a virus planet, but the current research on Pluto is still very shallow. <>

In the future, humans will explore PlutoSince the current level of human scientific research is not enough to support human civilization to travel in the solar system, the exploration of Pluto can only be carried out through astronomical telescopes and the speculation of scientists; However, with the continuous development and progress of human science and technology, scientific research capabilities will become stronger and stronger, and it is believed that in the future, human beings will also be able to have the ability to travel in the solar system, and human scientists are likely to be able to land on Pluto for field investigations, so many problems will be solved; It is hoped that human beings will be able to find life on other planets in the solar system and not live alone in the universe. <>

It's a relatively dark planet, the sun basically can't shine, and there is no oxygen and no nitrogen, which is really unjust.

Pluto was previously listed as one of the nine planets in the solar system, but it was not unjust to be removed from the list of nine planets because of its trajectory and the adjustment of its nature.

Pluto is a dwarf planet located on the outer reaches of the solar system, it is the largest and the second most massive of the dwarf planets. There is a lot to surprise about Pluto, which scientists define as the feared Pluto. Pluto was originally classified as a planet, but with the deepening of research, Pluto did not have the characteristics of a planet in terms of size, mass, shape, orbit, etc., and was finally downgraded to be defined as a dwarf planet.

In 1930, scientists discovered Pluto. However, due to the imperfection of astronomical rules and the limitations of the study of Pluto, Pluto is classified as a planet. With in-depth exploration, I have a more comprehensive understanding of Pluto.

Pluto belongs to the dwarf planets in the Kuiper Belt, which is currently the largest and the second most massive dwarf planet in the solar system, but the mass is relatively small, only one-sixth of the mass of the Moon, which indicates that it is composed of rock and ice. Pluto orbits the Sun and is so far away from the Sun that it barely shines. Pluto's surface temperature is very low, close to sub-zero absolute temperatures.

Pluto has five moons around it, which is still a very special existence in the solar system.

The reason why Pluto was lowered from a planet to a dwarf planet was first of all because his mass and volume did not meet the standards and was too far from the planet. It is even smaller than some of the moons in the solar system. Pluto's orbit also does not correspond to the planet's trajectory.

Its trajectory is not in the same plane as the other eight planets. Looking at the planets, the farther away from the Sun the planet becomes, it appears gaseous, whereas Pluto does exist in solid form. In 2006, the International Celestial Body decided to kick Pluto into the ranks of stars through research.

Pluto is a relatively late planet and has been controversial since its discovery. With the continuous in-depth research, the correction and analysis of its various data can have a correct understanding. Pluto is also a relatively valuable planet in the solar system, but it is too far away to really understand.
