Planet Or Not?

Is Pluto a planet? Before we can address this query, we must figure out what "planet" means and consider how ancient Greeks used the names for Mercury, Mars, Jupiter, Saturn, and the Moon. It's nearly impossible to determine whether something is an airplane, UFO, or weather balloon by whether it flies across the sky or not, by its appearance.

It's a horrible beginning, in that it does not include Earth, and secondly, because it mixes unrelated things. However, there was little equipment for them to note how different the Moon was from Saturn, due to the fact that they couldn't observe the Universe's machinery.

Nowadays, it took several thousand years before the hard-working Dutch made the first telescopes, and now it has increased their admiration for the study of astronomy. After this marvelous accomplishment, they felt they could rearrange the solar system, an important step that no one could question.

They, therefore removed the Sun and Moon from the list of planets and gave Earth a new place of importance. If the spacecraft could orbit the Sun, it would be a planet. Since the invention of the telescope, discoveries of new planets, solar systems, and galaxies have begun to occur with each decade.

And lastly, this is the solar system we know so well: Nine planets around one sun. People can be expected to stare at this model and wonder, "Why do astronomers want to get rid of Pluto?" Photographs in textbooks misrepresent facts.

There's not much of a difference between lies and downright inaccuracies. Planets appear to be of equal size and appear to be equally spaced; however, they could be different. Here is our Earth, Terrans, and Jupiter is the size you expected--it is, but much, much larger than you can see.

we adjust the sizes of the planets on this diagram, it looks like watching the fullscreen HD will allow you to see Pluto, which will be difficult because of how close it is to the sun. In size, Pluto is far and away from the smallest of the planets.

But, aside from being small, it's no bigger than seven moons: Callisto, Europa, Io, our Moon, and Ganymede as well. Regardless of whether you show realistic sizes or not, size discrepancies remain a problem.

When you're looking at something this small, it's impossible to be aware of its true size, so it must be really far away, which would make drawing on a scale quite an undertaking. A bacterium would be about as long as a dust mite if you measured the length of a piece of paper on the journey from Mercury to Jupiter.

Pluto being far away from Earth, however diminutive, elicits cries of injustice from a small but vehement group. Let's begin by talking about a planet you may have never heard of: it's a fascinating cousin, Ceres. A planet previously unknown to astronomers was discovered in the void between Mars and Jupiter, which they named Ceres.

The next year, another small planet was discovered in the same area and was given the Greek name of Pallas. As it turned out, they discovered a third one, and it was just as interesting to find a fourth. For a few decades, children learned about the entire solar system's planetary lineup.

Because astronomers kept finding many more and concluded that they were like ordinary asteroids, a new class was created: the tiny bodies in the asteroid belt. Not a bad, because the kids now have found many asteroids, which is amazing if they were all planets.

Mars was first discovered in 1930 when the new planet Pluto was found, making it the ninth planet. When observed first from space, it was nearly the size of Neptune, but was later found to be much smaller. (At this time) dwarf planets, like Ceres and Pluto, were discovered orbiting in the same region of the universe.

While students memorized the Nine Planets, some astronomers worried that the size estimates for Pluto might shrink. As a result, they found lots of This problem would have remained open and unsolved as long as no one had found a body larger than Pluto in 2006. Scientists organized the solar system once again and placed the faraway Pluto and other objects into a new category called the Kuiper belt.

Pluto, misclassified as a planet and finally established as a dwarf planet, found a new place to call home. Instead, this is about understanding that 'planet' is a false dichotomy. While the first four have little in common, the rest of the planets are disparate; therefore, these planets frequently are not classified with the solar system and are commonly grouped with giants instead.

Now that we have the ability to look at other stars besides our own, and lonely brown dwarfs (dim, inconspicuous stars) we know exist, the term "star" takes on a different meaning entirely. As we discover more about the universe, it may fall out of favor. Categorically, for the time being, are: The sun, the Earth, the planets, the gas giants, asteroids, and the faraway Kuiper belt (including Pluto).
