The Bible says God created the heavens AND the earth...which to me leaves open the possibility of life elsewhere.

To sum up all the responses you've gotten to your query: The gravity at the surface of a planet works out to be directly proportional to both its density and diameter.

Earth-like but far too hot for any type of life? Doesn't sound very "earth-like" to me.

Earth-like but too hot Earthlike but too cold, earthlike but too big, earthlike but too gaseous, earthlike but too hot, earthlike but too small. What is earthlike when it isn't earthlike?
Ans. Whatever planet a scientist on a grant discovers.

This can't be true.. The bible says so!!! God only created Earth!! The Bible says God only created Earth? Scripture please. God is a Creator, why would he create such a vast universe for only us?

What is the mathematical formulae for gravity?

I'm curious if the gravity of a planet is affected by it's density. I know our gas giants aren't very dense yet they have extremely strong gravitational fields. Or is mass more of a factor than density? Post #6 pretty much answers those questions. It depicts a very dense gas giant ;)

Don't be too cynical. This is a pretty significant development. When pretty much all they've been discovering so far are gas giants 15 times the size of Jupiter, this is quite a new lead.

I can't write it out in proper mathematical form, but I know that the gravity from any given point of mass is directly proportional to that mass, and inversely proportional to the square of the distance from it.
When dealing with a uniform shell of mass (and planets can be thought of as just a bunch of concentric uniform shells of mass), the gravity, for all points outside the shell, is the same as it would be if all the mass were concentrated at the center.

Ive pretty much figured out that it matters how much there is not how densely it's packed.
In any case I don't think we would be walking around on the surface of a rocky planet 6 to 7 and a half times as massive as the earth.

An earthsize planet discovery is pushing the boundaries of what is possible. Soon, though, when the new hardware gets placed in space, there will be a lot of new planets found, including small, rocky planets. Earthlike is possible, but I wouldn't plan on it.

When you're on the surface, it does indeed matter how dense the planet is. But you're probably right that the gravity of this particular one is too heavy for anyone to be walking on, unless the thing's made out of really light material.

It has to be a typo, at 2M miles with an orbit of 1.94 days should have read 1.94 years. Am I looking at this wrong? What say you?

Again, refer to the pic in post 6.

Maybe they meant rotation?
A 2 day orbit would put it almost 1/2 million miles an hour (someone want to check my math?)

That kind of gravity only attracts moonbats.
