	Mercury
		Mercury was named by the Romans after the fleet-footed messenger of the gods because it seemed to move more quickly than any other planet.
		Although Mercury is not tidally locked to the Sun, its rotational period is tidally coupled to its orbital period.
		Mercury is marked with great curved cliffs or lobate scarps that were apparently formed as Mercury cooled and shrank a few kilometers in size.

	Mercury
		Mercury is the only body in the solar system known to have an orbital/rotational resonance with a ratio other than 1:1 (though many have no resonances at all).
		Mercury's interior is dominated by a large iron core whose radius is 1800 to 1900 km.
		Mercury is often visible with binoculars or even the unaided eye, but it is always very near the Sun and difficult to see in the twilight sky.

	Mercury: 4. Where is mercury found?
		Mercury moves from the Earth’s crust into the biosphere as a result of both natural processes and human activities.
		Mercury is only removed from the biosphere when it reaches sediments deep under the oceans or when it is immobilised in controlled landfills.
		Mercury occurs naturally in forms that are volatile, so mercury continuously evaporates into the atmosphere, from both soils and water.

	MESSENGER: MErcury Surface, Space ENvironment, GEochemistry, and Ranging
		Among these, Mercury is an extreme: the smallest, the densest (after correcting for self-compression), the one with the oldest surface, the one with the largest daily variations in surface temperature - and the least explored.
		Mercury's uncompressed density (what its density would be without compaction of its interior by the planet's own gravity) is 5.3 grams per cubic centimeter, by far the highest of all the terrestrial planets.
		Mercury's axis of rotation is oriented nearly perpendicular to the planet's orbit, so that in the polar regions sunlight strikes the surface at a constant grazing angle.

	4. Where is mercury found?
		Given the understanding of the global mercury cycle, current releases add to the global pool of mercury in the biosphere – mercury that is continuously mobilised, deposited on land and water surfaces, and re-mobilised.
		The only long-term sinks for removal of mercury from the biosphere are deep-sea sediments and, to a certain extent, controlled landfills, in cases where the mercury is physio-chemically immobilised and remains undisturbed by anthropogenic or natural activity (climatic and geological).
		Today’s emissions of mercury from soil and water surfaces are composed of both natural sources and re-emission of previous deposition of mercury from both anthropogenic and natural sources.

	Who'll stop the mercury rain? (4/5/04)
		Because much mercury falls within 100 miles of its source, utilities that buy credits instead of installing controls could worsen local mercury deposition--so-called hot spots--says Lynn Goldman, a pediatrician at Johns Hopkins University and former EPA official.
		But the Energy Department and industry are trying to develop technologies specifically aimed at mercury, such as sorbent injection--for example, shooting carbon dust into smokestacks, where it binds to the mercury, forming particles that can be sifted from the exhaust.

	[No title]
		Childhood vaccines contain doses of mercury that are in excess of the Federal Safety Guidelines, and evidence shows a link between these excessive doses of mercury, found in thimerosal-containing vaccines, and neurodevelopment disorders such as autism and speech disorders, as well as heart disease, according to a study.
		It is nearly incomprehensible that the well-documented, toxic mercury is still in many vaccines, years after federal agencies have mandated that thimerosal be removed from the hepatitis vaccine.
		Most people, physicians included, don't understand that the mercury preservative thimerosal is still used in most vaccines and is likely one of the major contributing factors to vaccine toxicity.
