field of the Earth acts like a shield against the solar wind, leading to a magnetopause position many planetary radii away from the planet, in contrast to the situation at non or weakly magnetized planets such as Mars and Venus. ... H Nilsson - Springer Netherlands 被引量: 28发表: 2011...
Imagine Mars, the planet of war, combat, and drive, tempered and contained in a languid Venusian world of pleasure and peace. Mars would need to compensate somewhat, potentially giving those with Mars in Taurus a very long fuse, and a preference for avoiding confrontation. ...
