Mini Earth?

Question

Constructive critisim welcome

Ok so we know these planets are out of reach but a crazy idea (one of many) of mine is that if we cannot travel there on a rocket and we dont have the technology to build anything better can't we build a mini type of earth like a 2nd planet and then launch that into space equipt with everything needed to study other planets/grow food/a few thousand people willing to go down in history and tons of other stuff i wont list but goes without saying.

Obviously this is just an idea and theres loads of problems like getting somthing of a decent size into space is hard but not impossible, a system to manouver this 2nd earth would take some thinking through but for every problem there are pluses like the distances wouldnt be such a problem the kit could be made and/or repaired in a safe enviroment, and so on...

As humans we could pull somthing like this off let it orbit earth for a few years to give it a proper test then send it to orbit what ever planet we like

This is just a quick overview of the idea theres alot more detail to it.

Sorry, Gerard O'Neill beat you to it. By 30 years.

I think the effort is better spent terraforming Mars, which would be tolerable in 100 years or less... but no breathable atmosphere for thousands of years.

I'd much rather live on a planet surface of hundreds of thousands of square miles to explore than in a tin can that a micrometeorite can destroy at any minute.

Answer 2

How about the ISS(International Space Station)? Isn't that what that is for? experiments and all where the astronauts go alot/
