Due to its toxicity, mercury is increasingly being phased out. Before the adverse effects of mercury were known, it was used in numerous products, in a variety of industrial processes and in crop protection products. This led to emissions into the environment, and consequently to humans and the...
Also, Mercury has no moons but is a fully-fledged planet like Earth. All the gas planets, including Jupiter and Neptune, have rings of dust. Jupiter's and Neptune's rings are not as big as those of Saturn and Uranus. 4 A planet does not have to have an atmosphere, but all the ...
