It's the planet Arbuckle, in the Hoag's Object galaxy and we don't know its composition because its sky is made of concrete.What is the biggest planet in the universe?
Where is it?
Is it mainly made of iron?
It took less than a minute to type in an appropriate search term and come up with e.g.:What is the biggest planet in the universe?

Nope.If the Earth has the same radius as Jupiter, and same mass too, means that the center has big empty space.
No it won't.Then we will have same g = 9.81 m/s^2.
No, a Jupiter-like planet will not have any land to use.Like this, the Earth will have plenty of land for us to use.
Nope.Of course the jupiter-sized Earth must have different revolution speed to maintain comfortable temperature for night and day.
Earth's dimensions are optimal for its mass.do u mean the Earth's dimension is the optimal for hosting lives?
Is your proposal to increase the Earth's radius by hollowing it out, while retaining the original total mass? Or to increase the Earth's mass and radius while maintaining its average density? Or what? You need to be clear.If the Earth has the same radius as Jupiter, and same mass too, means that the center has big empty space.
I'll need to know what you're holding constant before I can answer that.If the Earth is at the current location from the Sun, but the radius is the same as Jupiter, can you calculate its revolution speed to maintain current temperature?
Yes. The problem would be: how do you stop the hollow Earth from collapsing in on itself?Maintain the Earth's mass, increase its radius.
GMm/r^2 still applied, we still feel the same gravity, right?
Then we have more surface area to use.
Why would it be land area that increases?Not double, maybe increase the radius by 20%.
The surface will increase by a factor (1.2)^2 = 1.44.
We have extra 44% of land area to use.![]()
We could drain the oceans, or parts of them. That would be just as easy.Not double, maybe increase the radius by 20%.

Centrifugal force. Not saying the earth is by any means hollowYes. The problem would be: how do you stop the hollow Earth from collapsing in on itself?
.
If you spun it fast enough, that would cause the equator to blow off into space while the poles collapsed inward. Centrifugal force doesn't work evenly on a sphere.Centrifugal force. Not saying the earth is by any means hollow
