It seems that some astronomers have put the Planet X theory back on the board.

http://www.news.com.au/technology/science/astronomers-believe-they-may-be-about-to-discover-one-or-even-two-new-planets/story-fnjwlcze-1227132634086

Due to some recent observations they seem to think that there maybe 1 or 2 other planets out there in the darkness at the edge of our solar system (personally I still regard Pluto as a planet so in my books no.9 is already there).

Cheers.

Hmm, Nibiru... I thought that story was a myth. Never believed in it myself. Thx for the link Wiggo, will read it later on:)

Actually, I think that they have confirmed some other snowball/Icey orbs that are actually bigger than Pluto some time ago.

The original planet "x" theory was that another large gas giant was lurking out there somewhere and now that voyager has passed through the area with nothing altering it's track that idea has been put to rest. More objects in the size range of Pluto (planet 9 in my book) will be interesting but difficult finds.

Yup, I believe Ceres is one of them... Still, Pluto will always be a planet for me too:)

Wasn't the asteroid belt supposed to be the remains of a blown up planet?



Yes, because of Jupiter's gravity, the debris has never been able to form a proper planet again.

The "official" answer is that the bits never formed a planet in the first place because of Jupiter.

That's exactly what I said Chris.

[edit] I shouldn't have added the word again...

There might be some planets beyond Neptune:

We might call him Tyche:

I read somewhere that the infrared telescope used to find brown dwarfs would have found the planets by now.

In the end it becomes just armchair science.

Better care for your family and children instead, perhaps?

Eris. It's bigger than Pluto, has a moon, is 3x farther away.
Edit: Even though it's bigger than Pluto, it's still only about 1/5 the mass of Earth's moon. Pluto is very small.

Charon is very large in proportion to Pluto. She always has the same position in Pluto's sky! Fascinating...

Could you remember and find where you read that? Perhaps that telescope might have found something if it had been aimed in that direction with that task in mind, rather than the one it was actually programmed to do.

...


This might be where I saw it.

But it's too far to part of our solar system...

plunking this story here :)

Will a comet shower end life on Earth? Rogue star could send icy rocks hurtling into the solar system ...in 240,000 years

Far beyond the orbit of Neptune, trillions of comets left over from the formation of the solar system lie in wait in a region known as the Oort cloud.

Here they are kept in relatively stable orbits around the sun, posing little threat to Earth save for the occasional icy rock that ventures inwards.

But in the blink of a cosmic eye that could all change, as stars have been found that could pass near our solar system in 240,000 years - and it they might shower us with thousands of deadly comets.

Right now we have the technology to see it & have 2-3y of preparement...so that means:
1. randevue (tractoring it, maybe with sails)
2. nuke it (deflection)
3. sacrifice Moon for the impact (obliterate it in collision)

So not to worry to much...NEO-WISE is out there! ;)

Do you want to have a rethink on that one???

Firstly, what would happen to earths oceans if there no tides any more? Secondly it also affects the seasons and the rate of the earths spin, Thirdly all the moons fragments could cause as much damage on earth as the comet.

Not to mention the wobble that the Earth would suffer without the moon being there to balance it. ;-)

Cheers.
