Can something like that ever really be done?
Though no one has terraform a actual planet yet, the NIAC and Techshot Inc are working together to try to terraform Mars. Only their idea would not do the whole planet, but only in a permanent transparent like dome. The dome would produce oxygen producing bacteria and algae.
I don't know for sure if someone can really do this or not. But this could be a possibility for the future. A cool one too. I always thought that living on a planet that no one has really lived on before would be a very interesting a exciting experience.
In a way, we have also created ways for man-kind to breathe and live on non-breathable and non-livable places. For instance; scuba gear, hazmat suits, spacesuits, rockets, submarines, and the space station. However to make a planet livable, it takes a lot more than oxygen.

The Ideal Planet for Testing
The ideal planet for this job would probably needs to have:
Ideal Mass 6.4171x1023
Using Smaller or Bigger Planets
Now as for the planets with a larger mass, though it may or may not be possible to use them. It could cause some problems. For one it would have a higher gravity meaning a much thicker atmosphere. It might be possible that if people lived on these planets they would be more tired because of the extensive energy needed to move around. This could also cause problems with your body functions, the opposite of what happens when you are living in zero gravity.
However not all planets are made the same. In special circumstances a large mass planet might be okay for terraforming.
Ideal Atmosphere and Water
One planet class that would not be ideal for terraforming is a gas planet of any type. They would be very hard to remove the gases for the planet to ever be breathable.
As said above the planet's mass plays a big part on the its atmosphere. And the atmosphere plays a big part on the water you are going to use to help you terraform. Too thin of a atmosphere and you can't hold in the water. Too thick and you might hold in too much.
The reasons are if your planet is too far away from the sun even with the ideal mass, after adding an atmosphere it will still be too cold.
Where as a planet that is too close to the sun would get hotter after adding a atmosphere, because of the greenhouse effect.
Just so you know if nothing has yet been done to a planet it would be very cold to begin with. That is why the low is so low. But some planets that have certain gases would be hotter than the temperature above.
Also with less gravity than Earth's, you would need to exercise more to keep from having bone degradation.
Ideal Rotation and Orbit
The axis tilt would allow it to have moderate seasons. Too much though and the seasons could be extreme. While no tilt and the planet could get too hot or too cold on one side.
The rotation is also very important. For instance, having the rotation take too long would mean the days and nights would be longer. That would cause problems with the temperature of the planet being too cold for long periods than all of a sudden getting too warm. The rotations speed would also affect the magnetic field and its core.
But another thing you need to see is the suns type. There are several different types such as the classes O, B, A, F, G, K, and M. O being the hottest and M being the coldest. Our sun is under the class G2V, so it is not too hot or too cold. A sun that is hotter would probably suffocate us and a sun that is cooler would freeze us.
Living on Moons
- The planet the moon is orbiting could interfere with the tides of its oceans
- The moon gets to cold at certain times of the year because it is orbiting a planet not a sun
- Growing seasons could be affected.
The Idea Proposed in My Books Without Really Saying it
Day 1 Arrival
Because this is only day one, you would not actually start terraforming this day. You would start doing the math to make sure this planet would even work.
You would want to first want to check the sun's class. To do that you will need to check the sun's temperature. Somewhere between 5,200–6,000 K would be okay, this would be a class G sun. (Please note that another sun might be okay for the job, but I just thought keeping it close to Earth's status would be a good idea.)
Now check the distance the planet is from the sun. This will help you know the temperature of the planet's side closest to the sun. You will also want to know the lows.
Next measure the mass of the planet, the best units for the job would be kilograms or tons. The mass would also help you figure out the current gravity and atmosphere.
If everything is going well so far, the next thing you will want to do is calculate the tilt, rotation, and orbit.
First find all the moons that orbit around this planet, so you can figure out the tidal effect it would have on its oceans.
Also having some gas giants, in the same solar system might be a good idea.
Day 2-6 Probes
Day 7-150+ Building the Atmosphere
You are going to need to build up the atmosphere so it is like Earth's, which we had all ready talked about. But some of the things we had not yet talked about, is an ozone layer to help protect you against UV rays and you should also create an atmospheric pressure of around 100 kPa so we could walk on the planet without a mask or a pressure suit.
In Team Vergate (0) Before my characters kept the chemicals in containers before releasing it on the planet's surface.
Start with heavier greenhouse chemicals. Than release the ozone. Though this has never been done before, it should help hold in the atmosphere.
This would also help increase the temperature of planet's surface to the proper levels.
Day 151-155 Send More Probes to Check Samples
Day 156-306+ Growing Your First Plants
You will need to be the one to water these plants for awhile. As your planet can't rain yet.
Day 307 Release Small Animal Life
Day 308-458+ Growing More Plants and Making your Oceans
To do this you will need to fill the craters and canyons with your salt and fresh water, to make it so that it does not become stationary you will need to cycle the water.
Day 459-463 Send More Probes
Day 464-500+ Release the Animals and Building Your Structures
Day 501 Start Living
There could be problems like:
- Not enough air
- Gravity being too high or too low
- Temperature might not be warm or cold enough
But we really don't know as this has only been done in fiction.
But Isn't Terraforming Trying to be god?
You are not creating things out of thin air (for one reason the planet you want to terraform has no air). You are using the chemistry and science that God created to make a planet breathable.
He is the image of the invisible God, the firstborn of all creation. For by Him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities―all things were created through Him and for Him.
So to wrap things up, God has not told us that living on other planets is a bad thing anywhere in the Bible or anywhere else. We have not terraformed a planet yet, so it is not proven to yet be impossible. We have sent people in space before, so we know that is possible. Terraforming can be bad with doing it with the wrong intentions or without acknowledging that God was the one to create that planet and everything you're going to use.
