	~~The '''exosphere''' is the outermost layer of [[Earth]]'s [[atmosphere]]. Its lower limit is the ''exobase'' at about 500 km above the Earth's surface.~~		#REDIRECT [[Earth's atmosphere]]

	~~The exosphere is so thin that particles within it ([[atom]]s, [[molecule]]s, or~~ [[~~ion]]s) do not collide. As a result, particles in the exosphere can escape altogether from~~ Earth's atmosphere ~~into [[space~~]].
