But, it is possible to build a planet as like Earth with Atmosphere, Air, Water, Moderate Temperature, Gravity, etc. Theoretically, it is said we could build a planet like Earth. We could build our own planet right in our solar system for constant temperature as we get in our planet “Earth”. We could probably use asteroids in our solar system to build our artificial planet, but we are having only lower amount of asteroids in our solar system so we cannot build a planet as we expected so we are going to use OORT CLOUD to build our Artificial Planet but problem with this OORT CLOUD is it is so far from our Earth, we haven’t still invented that fast vehicle to bring that materials here, so this case could not help us. We have ...
