means A continuous stream of charged particles — mostly protons and electrons — blasted outward from the sun's corona at speeds of hundreds of kilometers per second, flowing past every planet and shaping comet tails, auroras, and magnetic fields as it goes.

from A 20th-century scientific coinage, not folklore: the term crystallized once physicist Eugene Parker theoretically predicted in the late 1950s that the sun's hot corona must be continuously flinging plasma outward rather than just radiating light, and spacecraft measurements soon confirmed it. 'Wind' was a deliberate metaphor — borrowed from ordinary moving air — to describe this outward rush of particles, even though it's not air at all but ionized gas racing through near-vacuum. The name stuck because the analogy works almost too well: it pushes, it gusts, it has 'weather.'
