Astronomers believe there are large numbers of both rocky planets and gas giants in the Oort Cloud, a vast cloud of comets approximately five trillion miles away - some 50,000 times the distance from Earth to the Sun...
Computer modelling and other astronomical clues suggest it may contain around 1,000 small planetary bodies, some of which may be the size of the Earth and Mars or larger.
Dr Alan Stern, a Nasa expert on the outer solar system described "forensic evidence" for the existence of large numbers of undiscovered planets in the Oort Cloud at the American Association for the Advancement of Science (AAAS) conference in Boston.
Dr Stern said the angle of Uranus's rotation suggested it had been struck by an object three to five times the mass of Earth at some time in its history...
"If you calculate how likely that was if there was only one such object around, you find that the probability is nil. In fact there ought to have been several dozen of these three to five Earth mass class objects around in order to make that event probable. Where have they gone? Computer models show us that they were probably scattered to the Oort Cloud, and we will eventually find them."

Interesting. You couldn’t hide a lage planet in the Kuiper belt but the Ort Cloud is out about 2 light years.
Sounds like the “stimulus” package, huh”
*sigh* maybe we should all move to one, now that Porkulus has passed...
>>he angle of Uranus’s rotation suggested it had been struck by an object <<
I bet that hurt...
Cordially,
I used to like the Red Planet but now....
but now the red head....Need I say more!
So now we just have to figure out how to manuver one of those puppies into an habitable orbit without smashing our home in the process.
“

Wow.
For that matter, it must hurt when Uranus is rotating. Let’s ask Barney Frank!
/bingo
OTOH, we have literally never had the capability to see it — so far. von Oort postulated its existence in order to straighten out equations derived from his own preferred hypothesis of Solar System origin.
My humble opinion is, there is no Oort Cloud per se. But there will be outer planets — most or all of which move in retrograde, as well as many being out of the ecliptic — and perhaps a wide, flat belt (more like a hat brim) of smaller, and probably captured, bodies.
We’ll probably be force-marched there.
HA.
:’)

“We’ll probably be force-marched there.”
May the force be with you.
Me, I think I would rather die fighting.
