Cool stuff, the kind of thing I've hoped for since I was knee high to a grasshopper.

QuoteAt least two planets larger than Earth likely lurk in the dark depths of space far beyond Pluto, just waiting to be discovered, a new analysis of the orbits of "extreme trans-Neptunian objects" (ETNOs) suggests.

Would be cool if it can be proven true.

Hmmm. Plenty more Pluto size objects but Earth size is unlikely I reckon.

Someone doing the Maths and working out error of margins of current tech. Anyone want to bet?

I have to agree with you, Snowy. If there's something out there larger than Earth, it's likely to be a VERY long way out, maybe even as far as the Oort Cloud.

Is that the same cloud where all the data is kept ? 

Data is in Brighton, isn't he???

Touché sir, Touché 

 

Those are asteroids outside our 8pla.net solar system.
