Planets

Our galaxy – the Milky Way – is a spiral galaxy with arms extending from the center like a pinwheel. Our solar system is in the Orion arm of the Milky Way. Our Sun is one of about 100 billion stars in the Milky Way. And our galaxy is just one of roughly 100 billion in the visible universe.

The planet count in our solar system has gone as high as 15 before new discoveries prompted a fine tuning of the definition of a planet. The most recent change was in 2006 when scientists reclassified Pluto as a new kind of object – a dwarf planet. Today we currently have 8 planets namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

I have mentioned earlier that Pluto was reclassified as a dwarf planet last 2006. What was a dwarf planet anyway? Dwarf planets are also just like planets but they were just too small to be considered as a planet. This new class of worlds helps us categorize objects that orbit the Sun but aren’t quite the same as the rocky planets and gas giants in our solar system. There are 5 dwarf planets in the Milky Way but there could be hundreds more of these small worlds far out there waiting to be discovered.

Many disagreed in 1930 when Pluto was added as our solar system’s ninth planet. The debate flared again in 2005 when Eris — about the same size as Pluto — was found deep in a zone beyond Neptune called the Kuiper Belt. Was it the 10th planet? Or are Eris and Pluto examples of an intriguing, new kind of world?

The International Astronomical Union decided in 2006 that a new system of classification was needed to describe these new worlds, which are more developed than asteroids, but different than the known planets. Pluto, Eris and the asteroid Ceres became the first dwarf planets. Unlike planets, dwarf planets lack the gravitational muscle to sweep up or scatter objects near their orbits. They end up orbiting the sun in zones of similar objects such as the asteroid and Kuiper belts.

Our solar system’s planet count now stands at eight. But the lively debate continues as we continue to explore and make new discoveries.

In our solar system, eight planets circle around our Sun. The Sun sits in the middle while the planets travel in circular paths (called orbits) around it. These planets travel in the same direction (counter- clockwise looking down from the Sun’s north pole).

The solar system is made up of two parts: the inner and the outer solar systems.

The inner solar system is contains Mercury, Venus,Earth and Mars. These four planets are closest to the Sun. While on the other hand, the outer solar system contains Jupiter, Saturn, Uranus, Neptune and Pluto.

The planets are interesting to study since each of them have different characteristics to discover which varies from one another. Each of these characteristics provides the distinction between them. For me, the planets are just like brothers and sisters in a one big family- the Milky Way. Each of them surrounds their father, the sun. We are living in the earth, the third planet in the solar system, the only planet that is available for us to thrive on. The earth is the only planet that has the right temperature and oxygen that enables us to survive. The Mars is also studied because it is said to have the potential of a new world for humans to thrive on. Unfortunately, it has no oxygen in it.

Extra Terrestrial

   Extra terrestrial comes from the latin words: extra (“beyond”, or “not of”) and ‎terrestris (“of or belonging to Earth”. It is defined as life that does not originate from earth. It refers to the alien life or simply the aliens. These hypothetical forms of life range from simple bacteria-like organisms to beings far more advanced than humans.

The extra terrestrial beings are believed to exist though proofs of their existence are still unknown.  Researches have been done to prove their existence but for now, since the research for these kind of beings had started, nothing has been proven yet.

Come to think of it. If there are these kinds of beings, it only means, it’s not only us who thrives in this universe we belong to. These means, there are threats in our existence. What if someday, there place would be so crowded already and they would decide to thrive on earth. As said earlier, they are far more advanced than humans therefore, if they will need our world, they could just simply eviscerate us. I doubt the humans would stand a chance.

But, think in a different manner, if they are really present maybe, we could ask for their help with regards to our problems here in our world since they are far advanced than us, maybe they could lend us some of their knowledge and technology. Can you see it? They would be a big help to us.

If they really exist, why didn’t they show themselves up? Fear cannot be a reason for this I think since, as said earlier they are far advanced than us. So, why will they fear us if they are far more powerful than us? Well, maybe, they were just a peaceful kind of beings and they have seen that humans can create nothing but chaos that’s why they are avoiding us.

One thing I just realized was that, if they have advanced technology, maybe, they were living with us as one of our neighbourhood or were just above us but we cannot see them. If my wild imagination was right, we are surrounded by aliens already in this world we thrive on.

Another thing, if these extra terrestrials exist, where does they live? And how do they live? How they reproduce? How do they look? I know you also have a lot of questions about them but all of these were still unanswerable.

Scientists continue to research and conduct experiments and expeditions in the galaxy in order to clarify whether or not these being exist.

Well, in my opinion, if they don’t exist, why do stories about them continue to grow and why do people and scientists continue to research about them, why all these stories and beliefs vanish. For me, I believe that they really exist and that they were just waiting for the right time to show themselves u ad lend us some help but for now, they just choose to remain as a belief so that people will not know anything about them because it would just create a great chaos between our races because humans, by its very nature, are greed not just in earthly things but also in terrestrials. I know that if one terrestrial would be caught, scientists would look at it as a great source of knowledge, a great source of fame.

Maybe if they just have seen humans as friendly beings, they might have shown up their selves from the very point that they have discovered our existence.
