These days, it seems like everyone wants to go out into space and live on new planets. Ratherthan depend on another pre-existing planet, could we make a new, proper planet ourselves?

To start with, if we d want to be living on it, we should find a good place in space to put the new planet. We’d want it to be in a habitable zone, meaning the planet should be at the right distance from its star to make sure there would be perfect temperatures and most importantly, liquid(液态的) water.

We’d also need the right materials to make the planet. Our Earth is made up of many different elements(元素). If we made our own new planet we’d probably want it to have similar elements and a similar structure(结构) We’ d also want enough water to form some oceans.

But even if we get all of the materials creating a new planet like Earth could have many troubles. It might be something more like a huge space station. It would be pretty expensive if we wanted it to be super big.

We would probably also need a lot of food since there s going to be many scientists and astronauts out in space working on this project!

According to NASA, each astronaut uses about 0. 83 kilograms of food per meal, including 0.12 kilograms of packaging(包装) material. Without the weight of the packaging material, we’d need about 780 kilograms of food just to feed one astronaut for a year.

Putting all these together could make it possible to make our own planet one day! In reality, creating a new planet would probably require a very modern technology and there would be tons of
