Why is Pluto no longer considered a planet?

https://science.howstuffworks.com/pluto-planet.htm

Reason Why Pluto it is no longer considered a planet:

Size: It is smaller than Earth's moon

Composition: It is dense and rocky, like terrestrial planets. However, its closest neighbors are the Jovian gas planets. For this reason, many scientists believe that Pluto originated elsewhere in space and was trapped in the sun's gravity. Some astronomers once theorized that Pluto used to be one of Neptune's moons.

Erratic Orbit: The orbit of Pluto is erratic. Pluto, orbits the sun at an angle of 17 degrees with respect to this plane. In addition, its orbit is exceptionally elliptical and crosses the orbit of Neptune.

Size of its moon: One of its moons, Charon, is about half the size of Pluto. Some astronomers have recommended that the two objects be treated as a binary system instead of a planet and a satellite.


Opinion: 

Pluto does not have to be a planet because of the characteristics in which it fails, especially because of its erratic orbit, since it crosses Neptune, another reason is because of its size since its moon is almost the same size.

Space Wheater

What is??

Space Weather is a term which has become accepted over the past few years to refer to a collection of physical processes, beginning at the Sun and ultimately affecting human activities on Earth and in space.

Weather At The Sun

The Sun emits energy, sometimes storms in the Sun release radiation and magnetic fields through the Solar System, sometimes passing through the earth and sometimes not.

Weather Around The Earth

When the radiation from the Sun reaches Earth, it runs into our planet's magnetic field and its atmosphere. The radiation and magnetic fields in space weather swirl around Earth. Earth is surrounded by the magnetosphere. It affects depending on what the storms from the Sun are like. But it also depends on how those storms flow around and through Earth's magnetosphere.

Changes In Space Weather

Like the climate on Earth, space weather is always changing. Some space weather storms form in minutes or hours. An "active region" in the Sun can last several days or weeks, which causes space storms during all that time. The sun has cycles; for example, the sunspot cycle of 11 years that brings storms.

Origin of Newton's Laws

The Greek philosopher Aristotle dominated scientific thought for many years. The first major blow to the ideas of Aristotle came in the sixteenth century when Nicolaus Copernicus published his model of the universe centered on the sun. Galileo Galilei was the next to challenge the ideas of the Greek philosopher. But it was René Descartes, who would add new depth and dimension to the inertial movement. In his "Principles of philosophy", Descartes proposed three laws of nature.

For Newton to establish the three laws of motion he had to go through various processes of different philosophers. And each of these philosophers giving different points of view, discovering these laws and Newton was the one who concluded them.

Newton had to study each of these philosophers in order to conclude all these laws since by the time the last philosopher modified these laws, Newton was a newborn.

Yes, they are useful because they are the easiest and simplest way to explain the movement and describe various aspects with simple formulas.

Recent News from NASA in Space

It is the first time that ice is found in the surface craters of the moon. This ice was found at the poles and was found more in the south than in the north, the concentration of ice in the south pole was in several craters in the center, while the ice in the north pole in a wider area. Ice on the moon could be an important resource for space travel, the mining of lunar ice and its conversion into fuel.


I think that with this ice you could make discoveries of the lunar composition, I also think that with the Moon Mineralogy Mapper (the instrument that was used to discover the ice) you can make more discoveries in other celestial bodies.
