There Was The Fifth Giant Planet In Our Solar System?

Astronomer David Nesvorny of Southwest Research Institute from Texas believes that our solar system may have had a fifth planet once near Jupiter, Saturn, Uranus and Neptune. He believes that this planet was designed in the depths of our galaxy in a moment of cosmic disorder. After carefully studying the Kuiper Belt and craters from the Moon, Nesvorny concluded that about 600 millions years ago in the life of our solar system unstable orbit dynamics appeared that affected giant planets and made smaller celestial objects scatter. So, some of them moved in the Kuiper Belt and others moved on the inside of the galaxy.There also existed an impact with the Moon and other planets. If things would have been like that, then changes in the orbit of Jupiter would have had devastating effect on large and small planets like the Earth, the last one being able to collide with Mars or Venus.

So, something was wrong. "My colleagues have suggested another way to solve this problem", said Nesvory in a press conference.

It was assumed that Jupiter's orbit could change very quickly and not too slowly. But it didn't solve the problem because all the computer simulations performed have shown that sudden change of Jupiter's orbit would have made the planets Uranus and Neptune to be expelled from our solar system. So, probably in our solar system there was a fifth giant planet. Introducing another giant planet with a mass similar to that of Uranus or Neptune made perfect computer simulations that is the result of today's solar system as we know it. With Jupiter remaining in his place the inner planets remained unaffected and the outer planets remained behind.

"The possibility that our solar system had more than four giant planets in the beginning and then some of them were ejected seem to be feasible conditions because recently scientists discovered a large number of free floating planets in interstellar space indicating that the process of ejection of planets is one that is currently happening", said Nesvorny.

Therefore, is this scenario were true this fifth planet could be Planet X?

NASA recommends 'No-Fly Zones' on the Moon

By the end of the month, it is said that NASA will come up with a list of 'recommendations' for any spacecraft or astronauts what will be going to the moon. They include the landing sites for the Apollo 11 and 17 lunar landers. Now, these recommendations will not be legally binding because of a treaty that was made in 1967 that states that the Moon has no real owner, but are still there to try and preserve the more than 30 historical sites that have been made on the moon by the U.S.

What made NASA make these recommendations to begin with was the Google Lunar X contest that consists of landing a robot on the Moon, having it travel 500 meters and take a picture or video of the lunar surface. Since taking pictures of one of the landing sites would most likely win the grand prize, NASA decided to try and stop the teams from doing so since it might ruin the original landing sites. Now, not everyone will want to follow these recommendations. For example, studying bacteria in the feces and food left by astronauts on the moon will show if the bacteria died out or how it mutated to survive the harsh radiation from the sun. Any metallic objects will show how they have degraded over time due to all the radiation exposure from the sun. NASA remains hopeful that people will try and respect these limits and that they try and preserve such historic artifacts.

Who Built The Moon ?

More and more theories assert that the Moon is not only a natural celestial object near the Earth who came in this place accidentally. Coincidences do not exist, there are only laws unknown to us. Believe it or not, but it seems that the Moon was created specifically to support life on planet Earth because it has some unique benefits for people. If the Moon did not have the size and weight that it has and if the distance between it and the Earth was not the one who is, then our planet would not have been able to support intelligent life.
