Tyche, Giant Hidden Planet, May Exist In Our Solar System

[RandySF]

We may have lost Pluto, but it looks like we might be getting Tyche.

Scientists may soon be able to prove the existence of the gas giant, which could be four times the size of Jupiter, according to astrophysicists John Matese and Daniel Whitmire from the University of Louisiana at Lafayette. The two first proposed Tyche's existence in order to explain a change in path of comets entering the solar system, according to The Independent.

1. Counter Earth?

:shrug:

2. Nope. More like a tiny dark star creating something like a

binary system with our sun. Very large and very far away, but too small to turn on as a star. We don't see it, but we can see it's gravitational effects. Once it's position is known, though, it should be detectable by its occlusion of stars.

3. I know. Counter earth is a once popular idea from comic book and sci fi.

I wasn't suggesting that people lived on a gas giant. ;-)

5. something that big should be visible by reflected light

we can see tiny little Pluto, how could we not see a Neptune that was twice as far away as Pluto? Or even four times as far away?

Anyway, I thought there was supposed to be another asteroid belt out there. Something that would have four times the mass of Jupiter but be divided up among 25,000+ very large rocks.

6. We may well be looking in all the wrong places.

There are only so many scopes and so many people looking for stuff. If the evidence that is about to appear truly demonstrates the planet's existence, it'll be found fairly quickly. Lots of sky out there, and most people are looking for stuff a lot farther off than a new planet.

If it's there, and the evidence shows that it is, it'll be found and looked at.

7. No, Tyche would be out in the Oort Cloud.....

Much, much further away than Pluto. Pluto is at 39 AU average, the Oort Cloud starts FIFTY times further than the orbit of Pluto.

http://en.wikipedia.org/wiki/Oort_cloud

The Oort cloud is thought to occupy a vast space from somewhere between 2,000 and 5,000 AU (0.03 and 0.08 ly) to as far as 50,000 AU (0.79 ly) from the Sun. Some estimates place the outer edge at between 100,000 and 200,000 AU (1.58 and 3.16 ly) The region can be subdivided into a spherical outer Oort cloud of 20,000–50,000 AU (0.32–0.79 ly), and a doughnut-shaped inner Oort cloud of 2,000–20,000 AU (0.03–0.32 ly). The outer cloud is only weakly bound to the Sun and supplies the long-period (and possibly Halley-type) comets to inside the orbit of Neptune.

12. No the theory is that Tyche IS in the Ort could. Estimated orbit is about 15,000 AU

On edit: I misread your post. We are saying the same thing.

Interesting is that to go 15,000 AU at 10% of speed of light would take almost 3 years.

4. Yep, already heard about this elsewhere.

It'll be interesting to see it. If you can.

Although, anything posted by the HP is usually a bunch of bullshit.

I don't want to get burned again like I did with the supernova thing.

8. Planet X!

11. The Sumerian Texts and to

give you an idea of what the Sumerians knew as far as it comes to our solar system, they depicted a solar system with twelve members, not just nine. They counted the nine planets that we know of plus the sun, our moon, and an additional planet called Nibiru, which meant ‘planet of the crossing’. Now this planet and the stories behind it are very interesting because the Sumerians very clearly described that these beings, the Annunaki, their living gods, came from this planet called Nibiru.

The Annunaki ....... well you just have to google.

But the texts are 2000 years older than the bible.

9. Pluto Lovers of the World Unite!

Nice to hear a new planet might get to take Pluto's position as #9, but is should really be considered #10. Poor Pluto. :(

13. They should call it Ronald Reagan instead of Tyche.

A failed star, way out there, made up of gas, with an icy core at it's heart and surrounded my aimless hard rocks?

18. ROFLMAO!

:rofl:

14. I am tinking they are barking up wrong tree....must be other explanation other than comets vering

[ellie]

15. Where is it hiding?

Behind the bookshelf?

17. if you consider kuiper belt objects bookshelves, then yes... kinda

but it is 3 times further out than Pluto
