The Early Solar System

Gravity: Gravity is a force of nature that keeps things on Earth instead of floating out of the atmosphere.

The solar system was created 4.6 billion years ago by a gravitational collapse. A solar system is a star that has planets, moons, asteroids, comets, and meteoroids travel around it. The solar system contains eight known planets which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Neptune. There is around several hundred dwarf plants but only five are currently recognized. The solar system has about 181 moons which orbit around the planets in the solar system. There is also about 150 million asteroids and 3,406 comets also in the solar system.

As technology improves it is even more likely that we will discover more about our solar system. A great current example of this is the claim of ‘Planet X’. Researchers say that there is possibly another planet in our solar system that orbits beyond Neptune but is large in size. Two scientists recently announced evidence that a body nearly the size of Neptune that orbits the sun every 15,000 years. Since it has never been seen, because it only orbits every 15,000 years, scientists and researchers cannot make a factual claim on the body even though there is strong evidence of its

"We are 100 percent confident that this is the first object bigger than Pluto ever found in the outer solar

The discussion about Pluto’s status in our solar system is still in question. The definition of a planet is changing as society advances and as time passes. We used to believe that Pluto was a planet which orbits the sun, but in a weird way since it’s orbit is quite odd compared to other planets in our solar system. Pluto is different such that, it has five moons and crosses Neptune’s orbit. Not only does it do that, it is quite small in contrast to the other celestial body in our solar system. As society advances, we question the definition of a planet and Pluto’s status in our solar system. Our crave for knowledge and curiosity about what’s around us motivates us to explore the unknown. Our desire to learn more is due to the fact that people

Once, Pluto was considered the ninth and most distant planet from our sun. Pluto was discovered by an American astronomer name Clyde Tombaugh in 1930. But before being discovered, an American astronomer name Percival Lowell was actually the first to caught hints of Pluto’s existence in 1905. He suggested that there was another world’s gravity that was tugging at the two planets, Neptune and Uranus, from beyond. It turns out that there was another planet, the smallest and ninth planet from the sun, Pluto. The now dwarf planet was named by an 11 year old girl from Oxford, England whose name was Venetia Katharine Douglas Phair or Venetia Burney. The astronomer did predict the planet’s location in 1915, but unfortunately he died without finding

"Planet Nine is possible, though it is going to be tough," Kuchner told CNN. "On the other hand, WISE data is a proven source of new ultra cool brown dwarfs, sometimes called rogue planets. I'm sure we'll find some of those, maybe even one that's closer than Proxima

As i was growing up all my science teachers will always say that there was 9 planets in our solar system. But as time went by, little by little the 9 planets started fading, now in days there still debating whether considering Pluto a planet or not. According to scientists, pluto does not meet the standards that fall under the category to be a “planet”. Pluto has many features that they considered to be a dwarf planet like: its large distance from the sun, that it doesn't have its own orbit, its temperature is extremely cold, all these facts are the reason why many people are still debating pluto's status. Pluto was found by Clyde Tombaugh, an astronomer from the United States in 1930.

The discovery of Uranus was a startling observation. It is possible that people had seen Uranus prior to 1781, but none had realized what exactly they were seeing – most assumed it was a star. William Herschel is credited for the discovery of Uranus, but when he observed it through his telescope, he didn’t think it was a planet either. He hypothesized that it was a comet, because it was moving too fast to be a star. It wasn’t until his observations were peer reviewed, by other astronomers who studied it and found that its orbit was nearly circular. This lead them to classify it as a planet. At the time of the discovery, the original model of the solar system was only five planets (plus the sun, and the moon). The known planets had been observed

Have you ever wondered about the origins of the solar system and how it evolved? The philae mission was a probe that went into space and landed on a comet to take pictures and get samples of the comet’s surface to hopefully get more information about the origins of the solar system and how it evolved. The philae mission was important for scientific research because it could give researchers valuable information about the origins of the solar system and how it evolved.

To begin with, there is more than one sun out there in space, and a sun can contain about one million planets in space. Scientists have discovered about one thousand planets orbiting distant stars. They have much more to discover! There is a big possibility that in one of those planets life could exist. Another big clue that scientist have discovered is that there are many galaxies in space and we live in one. The galaxy that Earth is located at is called the Milky Way Galaxy. A galaxy can contain many planets just like our galaxy can contains over billions of planets.

As humans, many unnecessary questions appear in our brain quite frequently, questions that will not really benefit us whenever we find the answer to it, but we are crazy to find that answer anyway. Humans are simply just very curious beings. Growing up, in elementary school, I was taught that there were nine planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. But today, in the year 2017, there are only eight because Pluto is no longer a planet. Pluto is the smallest and the farthest from the sun, so I predict that is one of the reasons that it can no longer be classified as a planet in our solar system.

After decades of Pluto being a planet, astronomers began wondering whether Pluto might just be the first of many small, icy bodies in the Kuiper Belt (BBC news 2015). it wasn’t until

Hypothesis: the anomalies in Uranus’s orbit could have been caused by another planet that lay beyond it.
