=The Physical Characteristics of Mercury= []

=
Mercury consists of about 70% metallic materiel and about 30% silicate material. Silicate contains silicon, in that silicon it has anion, most of silicate are oxides.It is believed that Mercury's core is high in iron.It is made mostly of metal and rock with silicate on the surface in tiny particles.===== [] Mercury's core is about 47% of Mercury.It appears as a morning and evening star but isn't as noticeable of Venus even if it is an extremely bright planet, it is still small and not that noticeable. It also has a rocky body, kind of like Earth's.The density of Mercury's is slightly less then Earth's, it is the second most density in our Solar System. The appearance of Mercury's is almost like the surface of the Earth's moon. Mercury also has hills, valleys, and crates just like the moon. Mercury has phases like the moon. Mercury has an atmosphere that contains hydrogen, helium, oxygen, calcium, potassium, hydroxide, magnesium, silicon and sodium. Mercury has 1.1% magnetic field, almost like the Earth's magnetic field. The surface of Mercury has been observed and is believed to have frozen "lakes" on the surface where it is not directly hit by heat. It is also believed the crates on the poles of Mercury contain the frozen "lakes". No one could live on Mercury because of lack of oxygen and intense heat.
