back to article NASA trumpets rocky exoplanet find

NASA has announced it's nailed the first "bone-fide" [sic] rocky exoplanet, which at 1.4 times the diameter of Earth is the smallest such body spotted to date outside our solar system. As its name suggests, Kepler-10b was identified orbiting star Kepler-10 - at a distance of 560 light years from Earth - by the agency's habitable …

Rocky?

I did briefly wonder how anyone could describe something with a density "similar to that of an iron dumbbell" could be described as "unequivocably rocky".

Then I remembered that the Yanks don't do irony......

Eh?

Why couldn't something with the density of solid iron iron not be rocky?

rocky?

I think TeeCee may have been a bit "rockonic" there.

No?

Please your self.

Re: Eh?

Well, with the right impurities and given the uncertainty of that 1,300 C - the iron might just be molten!

Conundrum: Is molten rock still rocky?

Mine's the one with the tungsten sample spoon in the pocket.

Molten

Even with impurities and allowing a little for inaccuracy I don't think you could account for about 250 centigrade of error.

Re: Molten

Actually a eutectic alloy of iron and antimony will be molten at 1300C - no error required (although that's a hell of a lot of antinmony), metals can behave strangely depending on the mix, take NaK as an example (Sodium and Potassium alloy) which is liquid at room temp.

Dumbbell

How different is the density of dumbbell iron from ordinary iron? or is the dumb in the wrong place.

"bone-fide"

Oh good Lord!

Still, well done on finding the planet, NASA

"bone-fide"

Shurely "bone, fido".

Or am I barking up the wrong tree?

Abusing the American Language is FUN...

bona fide, bono-fide, it is only a borrowed term anyway.

I guess that American-folksy terms just don't sound sweet to sophisticated European ears.

We will sleep well, anyway.

Another example of that law ...

... that says that you will always make a spelling error when you have pointed one out - it should be "minuscule", not "miniscule"!

(Even though I have assiduously checked this, I just know there will be an error somewhere!)

NASA finds Planet Hell?!?

That would be a great name, being so hot and so much iron.
