As seen from the Earth, the angle between Mercury and the Sun at greatest eastern or western elongation can be as large as 28° (when Mercury is near aphelion) or as small as 18° (near perihelion). By contrast, Venus follows a larger, nearly circular orbit with a 224.7-day period. The angle between Venus and the Sun at eastern or western elongation is 47°.. The Totally Terrific T’s.

Mercury has an affect on everything. Between soil on land, and sediment in water, sediment contains more mercury from being in the contaminated water.  Mercury has a huge effect on organisms. When mercury from power plants goes into the air, the mercury falls from the clouds when it rains, and lands in water, on the ground, and pollutes everything. Mercury affects how quickly organisms move, and makes them less tolerant to diseases, or harmful things. Mercury affects many different systems throughout the organism's body. (Mercury and health).
