As explained, it was kicked out of orbit. It now holds a highly elliptical orbit far away from the Sun. In fact, one revolution around the sun takes approximately 3,700 years. Currently it is several hundred AU from the sun. It is also possible that the planet is cloaked. Its inhabitants possess technology far greater than ours, so this would not surprise me.
Planet X is coming...
Well Brent, why not specify exactly how many AU distant it is? You know, right?
I'm gonna take a wild guess and say you don't know.
Well anyway, here's a problem.
1 A.U. is 1.496x10
13 centimeters. You're proposing that this planet is currently "several hundred" astronomical units away. What's several hundred? Let's say 400 is a good enough distance, m'kay?
Let's even say that is it's furthest distance from the sun. That will be about 6,000,000,000,000 meters away.
Further, from that point, you're suggesting it will take about 1850 years for it to approach its closest distance to the sun. Fair enough. That's approximately 58,386,000,000 seconds.
This gives an
average orbital speed of a mere 100.27 meters per second. To give you an idea of just how slow that is, a car driving 100 kilometers per hour (60 miles an hour) is driving at about 28 meters per second - so this planet is only about 4 times faster than a car on the highway, on average.
Now, let's make an estimation that halway through its orbit this planet is moving at this average speed. At this distance from the sun, the deceleration rate of the planet is 1.483x10
-5 meters per square second. At a mere speed of 100 meters per second, given this deceleration rate, it would take only 156 days for the planet to stop and turn back around - not another 925 years. In the span of 156 days, even, the planet would only travel another 13 million kilometers, at that speed of 100 meters per second... not enough distance to reduce the deceleration rate enough to allow the planet to keep traveling for another 924.5 years.
However, let's also assume that right now the planet is 1850 years away from perihelion - that is, it's as far away as it can be right now. That means that the last time it came around was 1850 years ago, or about AD 150, give or take a few years.
Now, given that ancient astronomers could easily track objects the size of Mercury and Venus, there ought to be records of an object the size of earth suddenly appearing as a super-fast star in the sky, somewhere in the records of the Chinese, Hebrews, Greeks, Egyptians...
Ah, but there isn't.
Well, let's be fair and say that Nibiru last came through about 3500 years ago, and is now a mere 200 years away from coming close again.
That would mean its last pass was 1500 BC, approximately. Not clear that anyone would have recorded its coming back then.
However, if it is a mere 200 years away from closest approach, we'd actually be able to see it right now.
So pretty much no matter how you look at it, there ought to be either existing empirical evidence for this planet, or there ought to be new empirical evidence for this planet.
(and you thought that a degree in astrophysics was over-rated... boo.)
