Magnetic fields similar to Earth's are common throughout known space and many undergo similar flux transfer events. During its second flyby of the planet on
October 6, 2008, the NASA probe
129:’s magnetic field shows a magnetic reconnection rate ten times higher than Earth's. Mercury's proximity to the Sun only accounts for about a third of the reconnection rate observed by
79:
of Earth. Approximately every eight minutes, these fields briefly merge, forming a temporary "portal" between the Earth and the Sun through which high-energy particles such as
536:
83:
can flow. The portal takes the shape of a magnetic cylinder about the width of Earth. Current observations place the portal at up to 4 times the size of Earth.
63:
probes have flown through and surrounded these FTEs, measuring their dimensions and identifying the particles that are transferred between the magnetic fields.

Most recently, it has been found that the same phenomenon, also known as a 'magnetic rope', can be observed at
140:. The findings prove that at times Saturn "behaves and interacts with the Sun in much the same way as Earth".
