Our solar system is filled with stars, eight planets, some dwarf planets and plenty of comets and asteroids. A number of centuries in the past, individuals thought there were more than eight planets. They erroneously marked the asteroids as planets, discovered non-existent planets and predicted the existence of some other planets
Some of these predictions materialized – resembling Neptune, which was discovered after its existence was predicted. Nevertheless, many have remained hypothetical. We consider some of these planets may exist, however we all know that others aren’t. Nevertheless, we must all the time maintain our fingers crossed.
Vulcan is a hypothetical planet believed to be between Mercury and the solar. A number of centuries ago, in line with the astronomers, the planet was steered that Mercury had barely changed its orbit round every revolution.
In 1859, the French astronomer Urbain-Jean-Joseph Le Verrier instructed that this was because of the gravitational drive of an undiscovered planet between Mercury and the sun. He referred to as it Vulcan after the blacksmith's Roman god. Le Verrier added that the planet could not be detected because it was too close to the solar.
A yr later, an newbie astronomer Edmond Modeste Lescarbault claimed that he had found a small black spot near the sun. Le Verrier stated the point was the planet Vulcan. Other astronomers later claimed that that they had found an inevitable planet, although some insisted that they could not see it.
Vulcan was quickly considered the primary planet of the solar system, though there was no concrete evidence. This was in all probability because of the reality that Le Verrier was an astronomical authority. 13 years earlier, he had proposed Neptune after he found that the undiscovered planet changed the orbit of Uranus. As well as, Vulcan's existence was the only rationalization for Mercury's occasional orbit.
This changed in 1915 when Albert Einstein's common relativity principle rejected all the claims about Vulcan's existence. Einstein stated that giant objects, such as the sun, could bend time and area. The orbit of mercury modified ceaselessly as a result of it handed via a "distorted space time" on account of its proximity to the solar. 
Tyche is a hypothetical planet situated someplace in the Oort cloud on the sting of the solar system. The planet was proposed in 1999 by three astrophysicists from Louisiana University. Trio recommended that Tyche is the dimensions of Jupiter, Jupiter's mass is threefold and the solar is circulating once in 1.8 million years.
Astrophysics specialists instructed Tyche to elucidate the existence of long-term comets. These comets final greater than 200 years to complete the orbit around the solar. Astronomers believed that long-lasting comets got here from occasional places in the solar system.
Nevertheless, astrophysics specialists say that comets come from the Oort cloud and are pushed in the sun by the gravitational energy of Tyche. NASA used the WISE widescreen telescope to seek out Tyche between 2012 and 2014. It couldn't find anything. 
8 Planet V
The flood of asteroids hit the surfaces of Mercury, Venus. Earth, Mars and Moon 3.8 billion years in the past. Scientists call this to stop late heavy bombing (LHB). Nevertheless, they can’t affirm where the asteroids came from.
Some scientists have instructed that asteroids came from the remains of planet V between Mars and the asteroid belt that separates Jupiter from Mars as we speak.
The researchers assume that Planet V was smaller than Mars, which may clarify why its orbit was closely altered by the attraction of Jupiter and different exterior planets. Planet V soon turned unstable and astrayed in the asteroid zone, flinging asteroids in the direction of Mars and different inner planets. Planet V itself was later taken to the solar or lengthy into the solar system.
Alternatively, Planet V could solely have steered away from the asteroid belt and crashed onto another planet. Some astronomers assume it crashed on Mars and created a Borealis basin overlaying 40 % of Mars. If this happened, the asteroids that fell on the inside planets have been in all probability fragments that thrown into area in the course of the collision.
Different astronomers say that the hypothetical planet V has never existed. They assume that LHB happened after Jupiter and Saturn moved their orbits and threw asteroids out of the asteroid belt in the direction of the inside planets. Others say that the cause of LHB was when Mars's gravitational drive broke a large asteroid aside. 
Scientists believed that Earth and Moon have been created after the planet they have been referred to as Theia. The collision brought about a smaller breakdown of Theia and sent fragments to area.
The researchers disputed this concept when the exams of the Moon stones revealed that Earth and Moon have been product of the identical material. At the moment, scientists consider Theia has hit the older country 100 million years ago. Both planets blended collectively to create the Earth. 
Astronomers believed that there was a lately found planet between Mars and Jupiter. The existence of a hypothetical planet seemed more actual when Giuseppe Piazzi discovered what was thought-about a Ceres planet in 1801. A yr later, Heinrich Olbers found what was thought-about to be the planet Pallas.
Olbers soon discovered that Ceres and Pallas have been previously a part of the identical planet. This religion strengthened when the planets Juno and Vesta have been found. Ceres, Pallas, Juno and Vesta have been later categorised as asteroids and have been thought-about to be the stays of a hypothetical planet referred to as Phaeton.
The astronomers of the day thought that Phaeton had damaged down and created four nice asteroids and each other in the asteroid zone between Mars and Jupiter at this time
Some astronomers thought that Phaeton had damaged down after its explosion, Jupiter destroyed or had broken into one other heavenly physique. Some assume that this celestial physique is a Nemesis, a hypothetical star that was believed to be our solar system.
Nevertheless, as we speak's astronomers have denied the existence of Phaeton. They say that asteroids in the asteroid zone have all the time been asteroids. They have been stuck between Mars and Jupiter and would have grow to be a planet if there had been no Jupiter large attraction that stored them apart. 
Nibiru is a hypothetical planet that presumably lies someplace in our solar system. Although NASA says it doesn’t exist, conspiracy theorists harassed that it was real and slam in the bottom in 2012.
Nibiru can also be referred to as Planet X and shouldn’t be confused with the hypothetical planet of nine Additionally it is referred to as Planet X. We’ll quickly have nine planets.
Zecharia Sitch proposed Nibiru for the primary time in his 1976 ebook "The Twelve Planets", in which he claimed to flow into the solar every 3600 years. Many years later, self-proclaimed psychic Nancy Lieder announced that foreigners had warned her that Nibiru would shut the earth in 2003. Later she changed the date to 2012.
In 2011, Comet Elen handed the Earth and broke on Earth in 2011 to fly too near the solar . Onerous-liners insisted that the comet was a Nibiru planet that approached the Earth. The very fact that we read this text means that the Nibiru planet in all probability doesn’t exist. Or it just lost the earth and returns to 3600 years. 
four Planet 9
Planet 9 is one other hypothetical planet someplace in our solar system. In contrast to Nibiru, NASA and astronomers at the California Institute of Know-how assume that Planet Nine could exist despite the fact that there isn’t any verifiable evidence. Astronomers speculated on the existence of Planet Nine after they found the irregular threads of five sun spots outdoors of Neptune.
Astronomers assume that Planet Nine is identical measurement as Uranus or Neptune, whose mass is 10 occasions more than the Earth, and is 20 occasions further than Sun as Neptune. They consider that Planet 9 will take 10,000 to 20,000 years to complete the revolution around the solar. 
Within the fourth century BC, Greek thinker Philolaus prompt the existence of the planet, which he referred to as the Earth. He believed that Counter-Earth was all the time on the other aspect of the planet's solar system. This meant that the sun, the earth and the counter have been all the time in line.
Philolaus believed that the earth was invisible from the Earth as a result of the solar all the time coated the earth. In the present day we all know that it could by no means have existed. If that have been the case, we might have seen it on Earth because the planets of different solar methods affect the gravitational drive of other planets. This might have made it visible from the ground. Counter-Earth would have drifted nearer to the earth over time, and each planets would ultimately have met.
One of many two issues would have occurred once they met. Earth and Counter-Earth could run into a brand new country. Or they could have forgotten one another. If that they had, their gravitational pull would have been so massive that they might be thrown into new orbits. 
2 Unnamed Planets
Planets are sometimes unstable after their emergence. They typically change in orbit because the gravity of other planets is consistently drawing their orbit. In 2005, three theoretical groups used this concept to propose a Nice mannequin for the formation of a solar system.
Prior to now, the gravity of other planets pulled Uranus and Neptune to vary the cycle and sent Jupiter and Saturn additional away from Sun. Jupiter additionally moved nearer to the sun earlier than returning to the exterior solar system
The Good model was accepted till it was partially rejected in 2011. At that time, some scientists stated that Mars have to be the Fifth Planet and Jupiter to be true. Nevertheless, they added that the planet was more likely to have been pushed out of the solar system both by pulling Saturn or Jupiter's gravity
In 2015, the other model was challenged by different researchers because it didn’t clarify the creation of inner planets (Mercury, Venus, Earth and Mars). They stated Jupiter would have explored the internal planets, particularly Mercury and Mars, if it ever fell into the interior solar system.
4 inner planets would have been shaped long after the 4 outer planets, if the Good model have been true. Or they could be the survivors of the Jupiter apocalypse. This implies that the opposite inner planets threw away the solar system together with one or two planets from an exterior solar system. 
Sumeri believed that the planet Tiamat was positioned between Mars and Jupiter. Nevertheless, it has been discussed where this planet is immediately. Tom van Flandern claimed in the Darkish Matter, Lacking Planets and New Comets that the planet was destroyed 65 million years ago and became an asteroid belt.
Zecharia Sitchin denied this in her books The Twelfth Planet and The Cosmic Code. As an alternative, he announced that Tiamat had changed the orbit and is now Earth. Sitch stated that after the orbiting collision, Tiamat moved a hypothetical planet referred to as Marduk and its three months.
Sitch claimed that the collision shaped a new planet that broke half. Two elements moved closer to the sun to grow to be the earth and the moon, whereas the rest turned an asteroid belt. Sitch added that the previous cubes of Tiamat additionally thrown into new orbits. He believes that one of the Moons fell to Mars and created an incredible riff
