Exosphere of mercury
WebMercury Exposure --- Kentucky, 2004 In November 2004, a student aged 15 years brought a small vial of liquid mercury onto a school bus and into a high school in Kentucky. A subsequent investigation revealed that mercury had been in the student's possession for more than a year and that substantial amounts had been spilled in multiple locations.

WebThis type of tenuous atmosphere is called an exosphere, which on Mercury extends from space all the way down to the surface of the planet. It is generated mostly by the interaction of the sun with the planetary surface materials, as well as bombardment by meteors from space and the radioactive decay of elements within the crust. WebMay 1, 2009 · Intensive emissions from Mercury's neutral exosphere reveal the existence of sodium, calcium, and magnesium in the exosphere. This material is sputtered off by energetic electrons hitting the surface. High-energy electrons are produced by various dynamic processes within the magnetospheric plasma.
