The magnetosphere of Uranus at 1986 solstice (the time of the Voyager 2 flyby). Upper left and right panels show the configuration at different phases of the planet’s 18-hour spin period (see Bagenal, Ann. Rev. Earth Planet. Sci., 20, 289, 1992). The lower panel shows a numerical simulation of the helical magnetotail (Toth et al., JGR, 109, A11210, 2004).

Magnetosphere of Neptune in configuration corresponding to 1989 (Voyager 2 fly-by) see Bagenal, Ann. Rev. Earth Planet. Sci., 20, 289, 1992. Over 19-hour spin period, plasma sheet in the tail changes from roughly planar to cylindrical.

The draping of tubes of solar magnetic flux around a conducting ionosphere such as that of Venus. The flux tubes are slowed down and sink into the wake to form a tail (after Saunders and Russell 1986).
