The name "Pluto" was first coined by American astronomer Frederick Williams Pulhap in 1930. It's often said that Pluto is "faster than it can breathe", but what does this really mean?
What are Pluto's climatic conditions?
Is Mr. Li's sentence really the fastest speed that exists in the universe?
Is Pluto's age younger than Earth's?
So how long does what we usually call a year need to be on Pluto?
What is the origin of the name "Pluto"?
With such a huge age gap on Pluto, what are the climatic conditions on Pluto?
How far is Pluto from the Sun.
While the distance of other planets from the Sun is measured in billions, Pluto's distance from the Sun is measured in billions.
Pluto's distance from the Sun is equal to nearly half the distance from other planets to the Sun.
Pluto's orbit is also very elliptical, half in the solar system and half outside the solar system.
And because Pluto is far away from the Sun, Pluto's temperature will change due to the heat it receives from the sun's rays.
When Pluto is in the closest position to the Sun, Pluto's temperature will rise to close to minus 200 degrees, and when it is close to the Sun, Pluto's temperature will naturally rise to minus 200 degrees.
For the Earth, this temperature difference is equivalent to experiencing the cycle of the four seasons in the universe, but the temperature change on Pluto can make the Earth change the four seasons insignificant.
The difference between a year on Pluto and a "year" on Earth has not been compared in the microscope, so how long does a year on Pluto take?
How much time does a year really take on Pluto?
One is that Pluto is smaller than the Earth's, and the second is that Pluto's orbit is elliptical.
Because of these two points, the year of Pluto becomes less easy to guess, if you look at it according to Pluto's orbit.
Then it should be that a year on Pluto is many times longer than a year on Earth.
Because a change in Pluto's elliptical orbit will make Pluto's year longer, is that not the case?
Actually, no, Pluto has its own year, and a year on Pluto is equal to 248 years on Earth, so a year on Pluto is 248 years on Earth.
So what does the theory of 70 years on Pluto say?
A year on Pluto is 70 years.
Pluto's orbit is elliptical, so Pluto's orbit has a certain width range, which also means that Pluto's journey varies throughout the year.
Thus making the year of Pluto less difficult to guess, when Pluto moves from the orbit to the closest position of the Sun, and to keep it in the farthest position.
This distance is almost 1.8 billion kilometers away, which means that Pluto travels almost 3.6 billion kilometers in a year.
So the distance traveled per second is almost 11,000 kilometers, what is this speed?
Suppose a car travels a distance of tens of kilometers every second, but Pluto's speed is several times the speed of a car.
As a result, there will be a big difference in age and time.
And the maximum time and age gap on Pluto is 70 times, so suppose a person can stay on Pluto for only 30 seconds.
And these 30 seconds are equivalent to 40 years of Pluto, so when he lives on Pluto for 30 years, he must be old.
Pluto's climate.
Although Pluto is a relatively small planet, the temperature on Pluto is very low.
The temperature on Pluto's bicycle is only minus 200 degrees, which also makes the atmosphere on Pluto very thin.
At the same time, it also has similar characteristics to the earth, such as Pluto's atmosphere contains trace amounts of methane, carbon monoxide and other components, which is enough to show that there is almost no air in Pluto's atmosphere.
Pluto's atmosphere freezes on Pluto's surface in the winter and gradually returns to a gaseous state in the summer.
So how long is a "day" on Pluto? A "day" on Pluto is equivalent to "6.4" Earth days.
In other words, a day on Pluto is 6.4 times longer than a day on Earth, and a year on Pluto is equal to 248 years, so how long is a "year" on Pluto?
A year on Pluto is 87,760 Earth years.
So the time on Pluto is more than 40 times longer than the time on Earth, so what is the concept of one second on Pluto?
That's our whole life, and even life is gone, so it only takes a second for you to die.
epilogue
Teacher Li said that "it only takes a second to die, and Pluto's time is faster than everything".
Even on Pluto, Pluto's year is faster than everything else.
So how did Pluto form?
About 4.5 billion years ago, both the Sun and Pluto were born from a stellar cloud.
During the birth of the sun, the sun is in full swing, and part of its matter forms the solar system itself, while part of the matter outside the sun forms a huge gas mass.
Over time, the core of the sun produces a huge amount of energy, which pushes everything other than the sun out, thus forming the solar system.
Pluto also made its own changes after its birth, that is, Pluto was originally a relatively large planet, pushed from the solar system beyond the sun.
