how far out would be trying to transform a "dead" planet be?

My silly question of the week:
I don't know if either say Mars or Venus are in that "goldilocks zone".
But if they were, how far out would it be to try to reintroduce life on one of them or on another planet in the zone somewhere? I'm sure it would be more than just introducing water since comets hitting them probably do that from time to time (granted, probably not often).
But I'm guessing there would need to be some type of atmosphere and I'm not sure how those come about.

Part of it has to do with gravity. I would think atmosphere would be the hardest thing to overcome.

really?? how do you NOT know this?
it's pretty simple.... does the planet in question have liquid water and an atmosphere that can sustain life? if not, it's inhabitable for human life... period

Well there's a lot of factors involved that make each planet unique. Mars for instance we have most of the technology we'd need to terraform it, with greenhouse gases, trees, and redirecting large meteors to the surface, but there's one major problem we haven't addressed: it doesn't have a magnetosphere. How we'll do that I have no idea.
Venus requires vastly superior technology compared to what is required for Mars. We have to pump out billions of tons of its atmosphere and then try and stabilize the planet. Mars (save for the magnetosphere) you mostly just have to pump in stuff that is readily avaliable. Venus would require vast changes to the planet. It's plausible we could terraform Venus, but I would think it'd take thousands of years to do so. Mars probably 400 years or so.

Venus would be harder than mars. Its almost 900 degrees on Venus which is hotter than on mercury.
Mars is our best shot as far as we go. First stages would be building into the planet. Like in the original total recall

Simple. Just put a big magnet in the center of the planet. Problem solved.
If that seems overly difficult, then free all the iron from the iron oxide on the surface and put that in the center.

Supposedly you can heat up Mars to create a magnetic field. How to sustainably do that below the mantle, I have no idea. Small magnetic fields are possible, but large scale, it's too power intensive

Not to mention a day on Venus literally lasts longer than a year there. We'd have to great speed up its rotation, which would burn more energy than the rest of the project combined.

Really need a magnetosphere before anything else. Otherwise solar winds will strip the planet of its atmosphere. Mars does not have a magnetosphere.

It's gonna be ok man. Lots of guys get cheated on

Its relatively trivial to do. We've had the ability for decades

It would need to have a magnetic field to protect us from solar radiation. Then you can just nuke the polar ice caps if it has them to melt all the ice and voila.

Mars has no magnetosphere. This would make things difficult for establishing life from earth.

Just need the Genesis device. Your good

Technically, Earth's not in the Goldilocks zone either...

Not hard to do at all bro....you just need to decolonize your mind and try some black magic.
