Analogues

Venus possesses a similar tail due to the induced magnetosphere formed by interaction of the solar wind with the venusian atmosphere. On January 29, 2013, ESA scientists reported that the ionosphere of the planet Venus streams outwards in a manner similar to "the ion tail seen streaming from a comet under similar conditions." While Mercury lacks an atmosphere, the MESSENGER mission observed magnesium and sodium flowing off the planet, along the magnetic field lines trailing behind the planet, making them the primary components of Mercury's magnetotail.
