Another planet in our Solar System ten times the size of Earth, how do you miss that? Apparently there could be loads of these things.
Also Planet Nine...a title waiting for a movie. http://ri.search.yahoo.com/_ylt=A9mSs21Fn6BWFl0AkwFB4iA5;_ylu=X3oDMTBydHRqMjgyBGNvbG8DaXIyBHBvcwM1BHZ0aWQDBHNlYwNzcg--/RV=2/RE=1453395909/RO=10/RU=http%3a%2f%2fwww.independent.co.uk%2fnews%2fscience%2fplanet-9-secret-dark-world-could-be-hiding-in-our-solar-system-a6823646.html/RK=0/RS=.mbEQ52NXf4w5JgAcUyIhTU0_CM-

Space is big. Really big. You just won't believe how vastly hugely mindboggingly big it is. I mean you may think it's a long way down the road to the chemist, but that's just peanuts to space.

It was hiding behind Uranus

but we already have 9 planets...

Neptune, Pluto, Uranus, Saturn, Jupiter, Venus, Mars, Earth, Mercury

did they not proof read that article before it was published? They have miss-counted the planets... that's a biggy

I hadn't realised Pluto had been downgraded..

I was reading about the planet Nibiru theory a few years ago.

6 thousand years ago, the ancient Sumarians knew of a large planet with an orbit of 3000 years.

In before the Nibiru conspiracies

Tbh I dont really agree with the downgrading. The cynical part of me thinks it was a PhD candidate making a name for himself, or a bit of free advertising ahead of some tenured professors book.

But thats a discussion for another day.

The above reminds me of a quote from the film "Stand by me"

Gordie:
Mickey is a mouse, Donald is a duck, Pluto is a dog. What's Goofy...?

Teddy:
He's a dog, he's definitely a dog...

Chris:
He can't be a dog, he wears a hat and drives a car...

Vern:
Yeah, that is weird. What the hell is Goofy?

Officially its a dwarf planet. Its smaller than our moon, so is no longer classified as one of the planet of our solar system.

Planet hemorrhoids?

Lets name it planet Bob.

Nope. Though the guy who ran the New Horizons mission really wanted it to be, so they could call it the mission to the last planet or somesuch. May turn out to have been a moot point now I guess.

One planet in our solar system did once have the name George before it was renamed to the name we all know - and joke about - today.

Well anything that can have it's ass kicked by our moon doesn't get to be a planet.

It's pretty crazy that there could be a massive planet hiding in our own backyard, we were high fiving ourselves for being able to infer that we can see planets around other stars and that makes us sound like we're quite knowledgeable and know what's going on out there in space. But really we just know the basics, science has given us so much knowledge, but is always reminding us that there's so much we don't know too, and we'll never know anything about space for sure while we're stuck on this planet.

There is no Nibiru 'theory'. A 'theory' involves science and deductive reasoning. The word nibiru is simply the Babylonian word of the equinox -- it is not described as a planet.

The Sumarians only knew of five planets (which is really impressive actually!).

Most ancient peoples knew about the visible planets, they didn't know they were planets though, and the sumerian nonsense comes from one part of one picture and only makes sense if you completely ignore everything else we know about the sumerians.

How do you miss seeing something that's nearly impossible to see? Pretty easily I would guess.

To my knowledge they have not seen it. It's existence is being inferred due to it's gravitational influence on smaller objects in it's vicinity. And in fact this is nothing new really - just a new paper - as the existence of this planet (Once called Planet X back when we thought we had 9 planets not 8) has been talked about for as long as 100 years now.

Why can't they find it then?

Answer this question yourself. Go to an indoor football or basketball hall. Ask someone to turn out all the lights - black out all the windows - and then hide a small square of black paper somewhere in the hall.

Then go and try and find it.

When the New Horizons probe was launched Pluto was classified as a planet.
It was downgraded during its nine year trip there.

So, some maths.

We can see the moon because the light from the sun is reflected off the moon and back to us.

The intensity of direct sunlight at our distance is about 100,000 lumens. Of this, the moon reflects back just 0.001%, or 1 lumen. So the intensity in the sky of a full moon is about as strong as car headlight from 10m.

This theorised planet is about 200AU at it's closest pass. This means that the intensity of the direct sunlight on this planet is about 2.5 lumens.

If we assumed a similar rocky appearance as our moon, the reflected light from this body is about 0.000025 lumens.

This is about as bright as a car headlight from 2,000km away. That's assuming the body reflects that much light rather than absorbs it.

I say we blow it up, or invade the colony of intelligent life form on there before they get us. *gun shots in air* :eek::eek::eek:

Nash Bridges · 21-01-2016 04:25PM

It's difficult to comprehend distances in space. A good example goes something like this:
If the earth is the size of a basketball, the moon is the size of a tennis ball 8m or 24ft away. The sun is the size of a house 5km or 3miles away.
Therefore this new planet would be the size of a gym ball 200km or 125miles away.
Imagine all that bobbing in the sea in darkness with nothing else around. That's why its hard to find.

But, if we can't see a planet 200 times the size of earth how can we see the smaller objects it's influencing?

Or it is that we can see it ploughing through these objects leaving a trial? Like if something ploughed through the rings of saturn we could see the trail left in it's wake?

Or is it affecting objects much closer that we can see, pulling them out of the solar system towards it?
