Was Pluto removed from the solar system because of Charon?

The most important reason why Pluto was removed from the solar system was because Pluto could not rule over its own moon, Charon. When we were learning about celestial bodies in junior high school, the teacher introduced us to the earth, the solar system, the Milky Way, Orion and other stars, and the most impressive thing should be the solar system in which we live.

The original solar system was eight planets, until modern scientists discovered the existence of Pluto, Pluto was included in the category of planets in the solar system, until 2006 was kicked out of the ranks of the nine planets. There are many reasons for this, but before answering this question, we need to understand what a planet is. According to the explanation of the words, a celestial body that can be called a planet needs to meet three conditions:

The planet must revolve directly around the Sun, hydrostatically equilibrium (large enough), and clear its orbit (outstanding).

The first one is easy to understand, Pluto is one of the planets that orbits the sun. The second means that the gravitational pull of the celestial body itself is large enough for it to become a sphere. The third means that it can rule over all the celestial bodies in its orbit.

Pluto meets the first two conditions, but the third goes wrong and does not meet the definition of a planet. Pluto has five moons, the largest of which is Charon, which is nearly one-eighth the mass of Pluto, and the distance between the two is only about 20,000 kilometers.

The small weight difference between the two, as well as the short distance, caused both objects to be locked into each other's hands, with only one side facing each other at all times. Therefore, it does not meet the third definition of stars by astronomers, and cannot rule Charon, so it is judged to be a dwarf planet. Since then, the once famous "ninth planet in the solar system" has been kicked out of the solar system.

Pluto's atmosphere is harsh and not a place for us humans to set foot in. However, if you are interested in the future, you can go to play, sit in one place, and you can see a huge "moon" hanging overhead, which is still unique!

Not because Charon, but because Pluto is not a planet, and there are problems with estimating Pluto's mass, so it was removed from the solar system.

No, it's because of the discovery of other planets the same size as Pluto, creating a new species, dwarf planets.

It is true that because Pluto cannot control its own moons, it was downgraded to a dwarf planet, and it became famous as the Nine Planets.

Problem description: Isn't Charon a moon of Pluto? At least one level lower than Pluto, are they the twin stars?

Analysis: This is because the common center of gravity of Pluto and Charon is located in outer space, not inside Pluto, so Pluto and Charon are more like a binary star system, and they are equal companions to each other, rather than planets and moons.

The details are as follows: In 1978, when American astronomer James Christie examined Pluto's **, he found a clump of obvious lumps on its side, which inferred that Pluto had a moon.

Charon, which has always been regarded as a moon of Pluto, is not very large in its own right, with a direct permeability diameter of about 1,200 kilometers and a mass of about 1,45 of the Moon. But in terms of the size of the moon to its planet, it is the largest moon in the solar system. Charon orbits Pluto, they always face each other on the same side, Charon's own gravitational pull is large enough to make it spherical, and the common center of gravity of Pluto and Charon is located in outer space, not inside Pluto.

These characteristics have led some astronomers to believe that Pluto and Charon are more of a binary star system, with an equal companionship to each other than a planet-moon relationship.

Charon (translated as Karen in Taiwan Province) and Pluto form a double dwarf planetary system.

Charon was once thought to be a moon of Pluto, hence the name Charon, which was downgraded to a dwarf planet at the same time as Pluto at the International Astronomical Union meeting in Prague in 2006).

Charon is about 19,740 km away from Pluto, and Charon was discovered in 1978 by American astronomer James Christie.

The celestial rocks that orbit the star must be large enough to be considered a planet. Because it is only large enough that there is a strong gravitational force to clear other celestial bodies in the vicinity of the orbit, Pluto was downgraded to a dwarf planet because it did not meet this condition. Pluto was removed from the Nine Planets in 2006.

With regard to planets, three conditions must be met: orbiting the Sun, hydrostatic equilibrium, and emptying other celestial bodies in their orbits. Pluto's trajectory is interspersed with Neptune's trajectory and does not meet the third condition.

Dwarf planets also orbit the Sun and tend to be spherical in shape, but they are too small to clear other objects in their orbits. Pluto is now classified as a dwarf planet.

Pluto was mistakenly included in the list of large planets because of a miscalculation of its mass. Pluto's mass is much smaller than that of other planets, and even in the moon world it can only be ranked first.

Seventh or eighth place.
