> Without the magnetic field, the solar wind would strip our atmosphere, and the oceans would evaporate and be lost to space. In other words, Earth would end up like Mars. > The Earth is the only one of the rocky planets in our Solar System to have a strong magnetic field. Its presence is likely one of the major reasons why Mars and Earth are so vastly different. Venus has much denser atmosphere than Earth despite having weaker magnetic field and being closer to sun (possibly more affected by solar wind?). Why?
