Quit with this scientific crap :laugh2:

Wouldn't the gravitational pull be greater only if it has the same amount of magnetic minerals, proportion-wise?

No. Gravity is a function of mass, not electromagnetic force.

We'd be very uncomfortable on a planet twice Earth's size, assuming it were made of similar material as Earth. A planet twice as wide would have about eight times the mass, and roughly that much more gravitational pull at the surface.

What if it were made of downy feathers, but was large enough to have the same mass? That would be really comfortable. Unless one was allergic to downy feathers.

Of course. But a size limit was already given.

Also, eating would be unpleasant.

...Thinking of something else :laugh2:

Dude, you have no idea what you're talking about. I'm right and you're wrong.

I clearly missed your bus.

I don't know what gravity would be like on a planet twice the size of earth, made of downy feathers. Perhaps it could have a molten iron core, covered with feathers. As for the eating.....you make a good point. Maybe there could be islands of pulled-pork BBQ floating on the feathers. And a beer volcano on those islands.

How big is the core? And the mantle of feathers?

The beer volcano would be fine, but I've never cared for pulled-pork.

There will be no close up results in our lifetime unfortunately.

Even travelling at the speed of our fastest rockets it would take a round trip of 200,000 years just to get to the nearest star and back.

Even at the speed of light it would take a round trip of nearly 9 years.

Yep! We have a little bit of speeding up to do..:laugh2:

"There could well be an Earth-size planet in that Goldilocks sweet spot, not too cold and not too hot,.."

Goldilicks sweet spot!!!! :naughty::naughty::naughty::naughty:
