Planet-x-Nibiru
NEW PLANET,SPACE SEARCH.
When Pluto was discovered back in 1930, Planet Astronomers were also observing a massive terrestial mass in Space that caused fluctuations in the Planet orbits of Uranus and Neptune. So intrigued were they that this sparked a massive focus for the search for a new Lunar Planet, Planet X as it was so called,and it’s set to visit us soon.

N.A.S.A.’s CLAIM.
Where time in space is irrelevant, but back on Earth 1993 was a good year for N.A.S.A. They announced an Earth like Planet mass was traveling in an uneven orbit around the Sun. It’s trajectory was indeed discovered to be towards Planet Earth.

More recently adding credence to N.A.S.A.’s claim, was an article published on Feb.28, 2008 in Japan by a scientist named Kyoko Hasegawa from the Kobe University he said that their calculations, using computer simulations led them to believe that this Planet was up to two thirds the size of Earth and was in orbit at the far reaches of our Solar System.
It was only a matter of time before the mysterious Planet X came into view.

PLANET-X-NIBIRU.
So where does Nibiru fit in?
By talking up and manipulating the fore mentioned information, skeptics and believers alike both clung to the belief that this astronomical discovery was, and then declared proof that, Planet X and Nibiru were one of the same.

Planet X Nibiru measures approx. 30 to 70% of the Earths mass and is made up of Ice, Icy Ammonia and Methane. With that you can imagine the surface would be veeerrry cold. The Planet is in an oblong elliptical orbit and circles the Sun every 1,000 years or so. It’s radius is estimated to be 15 to 26 billion killometres. To put it into perspective, if you looked into Space, and managed to see Pluto the celestial size is estimated to be much larger than that and will leave a larger trail than Halleys Commet.

LOOK INTO SPACE.
Observers estimate that by the year 2012 this Planet like mass, will pass through our solar system and we on good old Planet Earth will get the front row seats.

Traveling from the surface of the Earth to surface of the Moon in 5 steps.

1. Launch from the Earth’s surface to reach Low Earth Orbit.

The first step on any ambitious adventure is typically the hardest. Step 1 is no exception, and is by far the hardest step. The rocket, fuel, and payload makes up the three major components. On the launch pad, the fuel can take up 90% of the total weight, leaving just 10% for the rocket and payload. That is the cost of accelerating to 5 miles per second, and the reason rockets are so big, when the payload can be as small as a few people. At that speed, the rocket will be less than half its weight, or half its mass, and circling the Earth. In preparation for step two, the rocket gets rid of the parts of itself that brought it here.

2. Launch from Low Earth Orbit to High Earth Orbit.

This step requires the rocket to accelerate again to go even higher, much higher than in the previous step. However, having less than half the mass, there is less to carry. Plus, the higher you go, the weaker the Earth’s gravitational pull becomes, making the job easier.

3. Launch from High Earth Orbit to Transfer Orbit.

Three items are considered in determining the speed for this journey, in chronological order: Earth; Sun; Moon. The speed must be high enough to leave Earth’s gravity completely, with some speed leftover. Then, the long distance to the moon, is actually calculated as an orbit around the Sun. That is because the Sun’s gravity overpowers the gravity of the Earth and Moon.

The last speed consideration is the Moon. Fuel is expensive and heavy, the less you take the better. But the Moon is much smaller than the Earth, so its gravity is much weaker. Therefore, you need fly just slow enough to allow the Moon to catch you in its gravity. That’s why it takes three days to travel to the moon. Travel any faster, the rocket will need extra fuel to slow down. No brakes in space.

4. Launch from Transfer Orbit to Moon Orbit.

Once you are close to the Moon, your orbit around the Sun becomes your orbit around the Moon. Gravity’s pull rises as you approach the moon, so you speed up a little bit.

5. Launch from Low Moon Orbit to the Moon’s surface.

Now to land on the Moon. You need to slow down, or speed up in the opposite direction of your orbit. That is why even this step is still a ‘Launch.’ Once complete, you should be hanging somewhere high above the Moon’s surface, where the rocket slowly and safely descends and lands.
