Huge 'Godzilla of Earths' discovered

Astronomers have identified a planet in a distant solar system that is 17 times the mass of the Earth.
Found using the Kepler space observatory, this gargantuan rocky world has a diameter of 29,000km and orbits an old sun-like star known as Kepler-10 which is approximately 560 light years away.

Its sheer magnitude has baffled scientists as by our current understanding of planet formation it shouldn't be possible for a rocky terrestrial world of such a size to exist.

"A mega-Earth is a lot of solids concentrated in the same place without any gas," said astronomy professor Dimitar Sasselov. "That is a problem because our understanding for how planets form requires the solids to get together in an environment where almost 99 percent of the mass is hydrogen and helium."

Scientists believe that this latest discovery could improve the chances of finding alien life elsewhere in the universe as it suggests that rocky planets can form much sooner than previously thought.

What is the deal with the earth and moon? Is the center of gravity within the earth or outside it? I always thought of earth/moon as a sort of double planet considering, except for Charon, that the moon is so large relative to the earth than any other moon. Many of the new exoplanets being discovered today, are actually detected by the fact that the parent star and the planet are orbiting around their center of gravity and not the center of the star. The effect is very small, but just enough that we can detect it. Unfortunately it works best with large planets orbiting close to the star. http:... [More]

maybe its a part of a even larger planet..and this might have broken.or chipped of from the mother planet. this concept would still still rationalize the fact about helium and hydrogen

Yes, meaning there is a lot more to learn. I realize that we know a lot, but the adage : the more you know leads to the more you know that you don't know. Of course, scientific infancy is my personal impression. Because we discover things that are amazing every single day, things we did not know prior. I suspect we will never exhaust adding to scientific knowledge. Modern, mainstream science is not complete. I don't think it ever will be either, that's the nature of science isn't it? It's supposed to be fluid and move with knowledge as it is added to. That process can never end. The universe i... [More]

...This rather limits the possibility of mega-moons. Yes. One logical place to start looking for a Mega~moon would be around a Mega~earth.

maybe its just a normal sized planet compared to all the other yet undiscovered earth like planets out there and where just a mega tiny earth Almost certainly not. The techniques that are used to discover planets find large planets more easily than less massive ones. If this was the normal size for rocky planets we would be discovering many of them. Also we have a fairly good understanding of how planets form. Massive planets like this usually hold on to a thick atmosphere and become gas giants like Jupiter and Saturn.

You didn't understand a single word I posted did you? I offered a suggestion to your comment... ...This rather limits the possibility of mega-moons. It is possible that a mega-moon was formed from a mega-earth in the same way our moon was created from our earth.

This does make me wonder. If we had full control over gravitational fields we could create an outpost on such a planet. Long term. Enough to terraform that world into something livable. Altering the gravity by .25(in the outpost) every three or so generation. So if the planet has a pull of 20 G then it would take 240 generations (at 3 generation per G increase) to be able to walk on the surface unaided. This would be a long process but the humans would be naturally adapted (hopefully) to survive. Forewarning my math might be wrong. If so, sorry.
