Mercury
Facts:
Mercury is the first planet of the SS, starting with the Sun and the smallest of all.
Its rotation period is 58.5 Earth days and its translation period (around the Sun) is about 88 Earth days. Is said to have an orbital resonance 3 / 2, every three turns on itself gives 2 turns to the sun This is important, but also will be discussed later.
By having this rOTING so slow it seems that it always faces the sun, but not exactly correct. For a long time one side is Diaye the other night, which causes a change in temperature (T th) interesting. Mercurial daytime temperatures reach about 425 º C and night about -170 º C.
has no atmosphere, but possibly long had, because now extinct volcanic activity.
An important detail is that Mercury is the second densest planet in the SS. This is because the core represents 41% of the total mass of the planet (the Earth is only 17% of the landmass).XC
