Unformatted text preview: geometry that includes relatively large contributions from non-dipolar components, including a strong quadrupole moment that may exceed the dipole moment in strength. By contrast, Earth, Jupiter and Saturn have only relatively small quadrupole moments, and their fields are less tilted from the polar axis. The large quadrupole moment of Neptune may be the result of offset from the planet's center and geometrical constraints of the field's dynamo generator.   Neptune's bow shock , where the magnetosphere begins to slow the solar wind , occurs at a distance of 34.9 times the radius of the planet. The magnetopause , where the pressure of the magnetosphere counterbalances the solar wind, lies at a distance of 2326.5 times the radius of Neptune. The tail of the magnetosphere extends out to at least 72 times the radius of Neptune, and very likely much farther....
