Beyond Uranus and Neptune deep in the outskirts of the Solar System lies an unknown large object. Irregularities have been occurring between the two blue-sister gas giants and that may be known as Planet X. A satellite-telescope has been launched last week to detect the heat from where this unknown gravitational pull is coming from. Including the Pioneer spacecrafts that are about to pass the orbit of Pluto. For the next six or seven months the satellite-telescope that was launched last week will detect infrared, that is invisible to the human eye, and will take a wide-range survey of the sky. That would then hope to find this object that pulls on Uranus and Neptune including others such as interstellar clouds, asteroids, etc. Astronomers have not had a serious search of the sky since 1930 when the ninth-planet Pluto was discovered.
Astronomers did witness behavior in the orbit of Uranus and that began a search of an outside-unknown planet. They then discovered Neptune and that halted on what they thought was the cause of the irregularity in the orbit of Uranus. William H. Pickering and Percival Lowell, two astronomers, in the late 19th century said that a larger object outside of Neptune had to be the cause of the irregularity of Uranus and not Neptune because it was too small. So they predicted the size and approximates of which lies beyond our Solar System that Lowell called Planet X. A quite time later at Lowell Observatory in Flagstaff an Astronomer the name of Clyde W. Harbaugh discovered Pluto. Only Pluto being the fifth of the Earth’s moon they proved that it couldn’t be the cause of Neptune and Uranus orbit behavior.
Dr. Thomas C. Van Flandern, an astronomer at the United Stated Naval Observatory, confirmed that a sing...

...t happen. The Internet is filled with a sea of hoax and it’s always going to stay that way with people making it up. YouTube is really popular at that. Some think also that the “government” is trying to cover it up
I personally do not believe in Planet X and I think it is the most outrageous claim someone can believe in. Ignorance and gullible is what I call that. I have some friends that think it’s real and really thought a planet called Nibru was going to crash into our planet and we all were going to die. I even had one pointing at Sirius and they were saying it was Nibru. The truth is that we detected something that was outside our Solar System and we thought it was a planet. Now with further evidence Planet X is nonexistent. If there were another planet in our Solar System heading towards Earth, the orbits of our eight planets would be all screwed up anyways.
...rst two letters of the name Pluto-was chosen as the planet’s astronomical symbol. Unfortunately, we learn later that Lowell’s Planet X theory is incorrect. In 1978, Pluto’s mass was found with the discovery of Charon, Pluto’s moon. Pluto, being a small planet, would have weak gravity. Therefore, this diminutive gravity could not affect the orbits of Uranus and Neptune. The International Astronomical Union reclassified Pluto as a dwarf planet in 2006. It was also revealed later that the strange orbits of Uranus and Neptune were due to the erroneous value of Neptune’s mass.

Neptune was discovered through a discrepancy in Uranus’s orbit. Uranus’s orbit was not moving how astronomers predicted it would. They could not find an elliptical orbit that fit Uranus’s trajectory. They therefore assumed that there had to be another planet that’s gravitational pull was effecting Uranus. Johann Galle was the first to find Neptune in 1846, even though many before him had mathematically predicted where this new planet would be. The planet was named Neptune and two astronomers who had predicted mathematically where it would be are credited with finding it not Galle.
Have you ever looked up into the night skies and wondered what might be out there? One question I always wonder is where in the universe might there be a livable planet? Well the answer might be closer than you think, well actually 588 million kilometers away from earth. Jupiter of course is what I’m talking about. Fell first let’s ask the why we might move. Let’s face it earth is not going to be able to be habitable forever in fact ate the rate humans are polluting the atmosphere earth won’t be around that much longer. So might need a new place to live. So could the answer be Jupiter? Before that we need to know a little about the new planet and if it’s able to sustain life. Let’s start with the Jupiter’s history. Jupiter is the largest planet in the solar system. Jupiter was named after the king of the gods and Roman mythology. The ancient Greeks named the planet after Zeus, the king of the Greek pantheon. In 1610, a man that goes by the name “Galileo Galilei” was looking through his homemade telescope when he came across Jupiter. He notice four objects circling Jupiter and described them as "four fixed stars, totally invisible by their smallness" it was there were he discovered four large moons Io, Europa, Ganymede and Callisto, which underwent several name change but are now known as the Galilean moons. This was the first time celestial bodies were seen circling an object other then Earth. Jupiter spins faster than any other planet, taking 10 hours to complete a turn on its axis, compared to that of 24 hours for Earth. This rapid spin makes Jupiter bulge at the equator and flatten at the poles, making the planet about 7 percent wider at the equator than at the poles. This is Jupiter and this is Jupiter next to the earth. Jup...
Indeed, most of the problem is that there is no formal definition of a planet. Furthermore, it is very difficult to invent one that would allow the solar system to contain all nine planets. I suggest that for an object to be classified as a planet, it must embody three characteristics. It must be in orbit around a star (thus removing the larger satellites from contention), it must be too small to generate heat by nuclear fusion (so dwarf stars are excluded) and it must be massive enough to have collapsed to a more or less spherical shape (which excludes comets, and most of the asteroids). These criteria would admit a few of the larger asteroids and probably some of the Kuiper belt objects as well, but adding a requirement for a planet to have a minimum diameter of 1,000 km would remove the larger asteroids from contention while retaining Pluto.
In conclusion, the discoveries of the Kepler mission have raised questions in many different fields about the possibility of extraterrestrial life. As we come to understand our universe more, the future of astronomy is beginning to resemble science fiction. All things considered, the field of astronomy is coming closer to achieving even more progress and possibly finding an answer to this perplexing question. For now, Kepler’s planetary candidates are under examination. The results are thrilling for not only science, but for human civilization.
In 1930, Clyde Tombaugh discovered Pluto making it the ninth planet in the solar system. However, in 2006 the International Astronomical Union decided to change the definition of a planet because there were other planets that resembled Pluto. This decision was made at a meeting in the Czech Republic. A planet now must be round, orbit the sun, and as they travel, its gravity clears the solar system paths of waste floating around. Since Pluto is not able to clear the solar system of waste because of its small size, it would not be considered a planet. Because of the change in definition, experts would still argue on whether Pluto should still be considered a planet. There were many different variations of the definition for planet which could resulting in having twelve planets including Eres and Ceres. Another definition would be leaving it to its original definition of having nine planets. The last variation would make the solar system only contain eight planets. This disagreement about whether Pluto being a planet or not can be associated with language as a way of knowing. Because of the change in language, there is disagreement about whether the new definition of a planet should be
The ninth planet Pluto lost its planetary status when it did not “make the cut” after The International Astronomical Union collaborated in Prague to finalize the definition of the word planet. The International Astronomical Union decided that there are eight planetary bodies in Earth’s solar system and that Pluto should be categorized as a dwarf planet. Online newspaper articles from 2006, the year The International Astronomical Union met in Prague, up until 2012 emphasize how the demotion of Pluto was presented to the general public. The articles covered within this six year span emphasize the more scientific aspect of the media’s portrayal of Pluto’s demotion. This timeline begins with the official demotion of ...

Pluto is usually farther from the Sun than any of the nine planets; however, due to the eccentricity of its orbit, it is closer than Neptune for 20 years out of its 249 year orbit. Pluto crossed Neptune's orbit January 21, 1979, made its closest approach September 5, 1989, and will remain within the orbit of Neptune until February 11, 1999. This will not occur again until September 2226.
'A discovery so unexpected could only have singular circumstances, for it was not due to an astronomer and the marvelous telescope…was not the work of an optician; it is Mr. Herschel, a [German] musician, to whom we owe the knowledge of this seventh principal planet.' (Hunt, 35)

Planet X has also been named Nibiru and is considered the twelfth planet. The name Nibiru came from a book written by Zecharia Sitchin. The book told about a twelfth planet with an oblong orbit. It was supposed to get near the earth every 3600 years. The book was called The Twelfth Planet. The book told the story of a group of aliens who modified people genetically so they would become their slaves. She said that humans evolved on Niribu and colonized the planet in some previous orbit. The aliens were said to return to earth to cause havoc in 2012.1 The whole idea of a “doomsday planetary collision” began with a lady named Nancy Lieder. She started talking about planets colliding in 1995 and she believed that had an implant in her brain that gave her the ability to receive messages from aliens. She claimed that she could communicate with aliens and that she was sent to warn humans that there would be a collision that would end life on earth. She predicted that this collision of planets would happen in May of 2003. When the event did not happen in 2003, Lieder and her followers decided it would happen in 2013. This was in line with the end of the Mayan calendar.
In addition to its moons, Pluto has a core, geology, seasons, and an atmosphere. Alan Stern is a planetary scientist with the National Aeronautics and Space Administration(NASA). According to Stern, “I can’t think of a single distinguishing characteristic that would set apart Pluto and other things that you’d call a planet, other than its size. So I like to say, ‘a Chihuahua is still a dog.’” Also from Discovery Education the text states, “Other astronomers have noted that their colleagues sometimes call Jupiter a giant planet. Why can’t Pluto be called a dwarf planet without being downgraded from planet status?” Another fact stated from Discovery Education was, “about 90% of the planets known to astronomers are outside Earth’s solar system. Some of these extra-solar planets do not fit the IAU’s definition of a planet. Yet IAU astronomers still refer to them as planets.” USA Today stated, “The debate among Gingerich, Williams and Dimitar Sasselov, director of the Harvard Origins of Life Initiative, took place Sept. 18 with scientists, teachers and civilians watching. Two of the three, Gingerich and Sasselov, said Pluto should be a planet. A vote among audience members agreed.” Another statement mentioned by USA Today was, “Harvard science historian Owen Gingerich, who chairs the IAU planet definition committee, argued at a forum last month that "a planet is a culturally defined word that changes over time," and that Pluto is a planet.” Finally from CNN they interviewed Alan Stern, a member of NASA, who said, “We're just learning that a lot of planets are small planets, and we didn't know that before” and “Fact is, in planetary science, objects such as Pluto and the other dwarf planets in the Kuiper Belt are considered planets and called planets in everyday discourse in scientific
