Induced magnetosphere Venus interacts with the solar wind. Components of the induced magnetosphere are shown. Venus is known not to have a magnetic field .   The reason for its absence is not clear, but is probably related to the planet's slow rotation or the lack of convection in the mantle . Venus only has an induced magnetosphere formed by the Sun's magnetic field carried by the solar wind .  This process can be understood as the field lines wrapping around an obstacle—Venus in this case. The induced magnetosphere of Venus has a bow shock , magnetosheath , magnetopause and magnetotail with the current sheet .   At the subsolar point the bow shock stands 1900 km (0.3 R v , where R v is the radius of Venus) above the surface of Venus. This distance was measured in 2007 near the solar activity minimum.  Near the solar activity maximum it can be several times further from the planet.
