(Hat Tip: Cosmic Variance)

Many space geeks (I included) seem to be excited about an image by KOKOGIAK displaying the 88 largest bodies in our solar system (of which 83 are “terrestrial” or have a surface we can actually land upon).

After searching online on these various worlds, many with an abundance of ice water upon them (a good sign), it became apparent that many of these worlds would not become favorable homes (for raising kids) due to either radiation, distance or lack of appeal.

Currently there seem to be four worlds that show some promise of becoming future homes which are:

  • Mars (which has tolerable levels of radiation)
  • Ganymede (which has a magnetic field)
  • Callisto (which is not within Jupiter’s radiation belts)
  • Titan (atmosphere plus Saturn’s magnetic field may protect it)

Unless artificial magnetic fields can be created upon other worlds, they may only attract corporate industries and scientists, but not the huge populations necessary in order to establish our species as a “space faring civilization.”

Hopefully I’ll get some more time to post about these four worlds, as they hold much promise for our race four or five generations from now.
