-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.
-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]].
