How long would it take to colonize the solar system?

The next secondary question is how long would it take to colonize a planet before it’s self-sustaining – estimates are hard to come by, but this post says around 350 years (source).

Is it possible to colonize the solar system?

Bodies in the inner Solar System have been considered for terraforming and space colonization. The main candidates for colonization in the inner Solar System are Mars and Venus. Other possible candidates for colonization include the Moon and even Mercury.

Which planet would be the easiest to colonize?

Venus has certain similarities to Earth which, if not for the hostile conditions, might make colonization easier in many respects in comparison with other possible destinations. These similarities, and its proximity, have led Venus to be called Earth’s “sister planet”.

Will humans conquer the galaxy?

The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

How long would it take to colonize Milky Way?

ACT has also posted a video of its solution to YouTube (see above). JPL found that it took around 90 million years for the teams to occupy large swaths of the Milky Way.

Can we colonize the outer planets of the Solar System?

Many parts of the outer Solar System have been considered for possible future colonization. Most of the larger moons of the outer planets contain water ice, liquid water, and organic compounds that might be useful for sustaining human life.

How long would it take to travel to the outer planets?

Some consider the upper distance to include the Oort Cloud (up to 3.3 light years, depending on direction…) So anywhere from 10,000 years (Neptune and inside)… to maybe 100,000+ years. It also depends on what kind of dwarf planets (or even planets) that might be found at the farther reaches.

Why do we need to study the moons of other planets?

Most of the larger moons of the outer planets contain water ice, liquid water, and organic compounds that might be useful for sustaining human life. Colonies in the outer Solar System could also serve as centers for long-term investigation of the planet and the other moons.

How many space colonies have been built so far?

No space colonies have been built so far. Currently, the building of a space colony would present a set of huge technological and economic challenges. Space settlements would have to provide for nearly all (or all) the material needs of hundreds or thousands of humans, in an environment out in space that is very hostile to human life.
