Garlic contains a chemical called allin, which is converted into another compound, allicin, when you chew a fresh garlic clove. Allicin is an oily chemical that decomposes very rapidly once it is formed, producing an acidic compound that reacts quickly with free radicals, destroying them.
Mercury is the smallest terrestrial planet in the solar system, about a third of the size of Earth. It has a thin atmosphere, which causes it to swing between burning and freezing temperatures. Mercury is also a dense planet, composed mostly of iron and nickel with an iron core.
It is the smallest planet in the Solar System, with an equatorial radius of 2,439.7 km. Mercury is even smaller âalbeit more massiveâthan the largest natural satellites in the Solar System, Ganymede and Titan. Mercury consists of approximately 70% metallic and 30% silicate material. Mercury's density is the second highest in the Solar System at 5.427 g/cmÂ³, only slightly less than Earthâs density of 5.515 g/cmÂ³.
