Je v\u0161ak jasn\u00e9, \u017ee zdaleka ne na v\u0161ech planet\u00e1ch m\u016f\u017ee existovat \u017eivot. Jednou z\u00a0podm\u00ednek je pak ur\u010dit\u00e1 vzd\u00e1lenost od domovsk\u00e9 hv\u011bzdy.

Nach\u00e1z\u00ed se tedy v\u00a0ide\u00e1ln\u00ed vzd\u00e1lenosti od sv\u00e9 hv\u011bzdy. V\u00a0takov\u00e9to z\u00f3n\u011b se nach\u00e1z\u00ed i na\u0161e Zem\u011b.\u00a0\u00a0Zd\u00e1lo by se tedy, \u017ee tato z\u00f3na bude velmi \u00fazk\u00e1.

Co se t\u00fdk\u00e1 t\u011bch lidsk\u00fd, je ve skute\u010dnosti mnohem rozs\u00e1hlej\u0161\u00ed, ne\u017e by se n\u00e1m mohlo zd\u00e1t.\u00a0Sta\u010d\u00ed se pod\u00edvat na na\u0161i slune\u010dn\u00ed soustavu.

Koneckonc\u016f podm\u00ednky na n\u011bm jsou tak p\u0159\u00edzniv\u00e9, \u017ee pokud by st\u00e1le je\u0161t\u011b m\u011bl magnetosf\u00e9ru, nebyl by pro \u010dlov\u011bka probl\u00e9m jej kolonizovat.

To je tak\u00e9 hlavn\u00ed probl\u00e9m kolonizace Marsu.\u00a0\u00a0Ov\u0161em, jak ji\u017e bylo \u0159e\u010deno, rud\u00e1 planeta nen\u00ed jedin\u00e1 potenci\u00e1ln\u011b obyvateln\u00e1.
