Mercury.
This planet is the smaller planet in the solar system (excepting the dwarf planets) It has a diameter of 4789km. It's formed in proportion of 70% metallic elements and a 30% of silicates. In Mercury, the high eccentricity produce a strange effect : the observer would see the Sun rise and then, stop, reverse its course and rise again. In one hand, Mercury is similar to the Moon in some ways. Both haven't got tectonic plate, and their surfaces are cratered and old. But Mercury is the second densest major body in the solar system (after Earth) This planet has a very thin atmosphere, consisting of atoms blasted off its surface by the solar wind. It hasn't got know satellites.

Its temperature is about 623 K (350 ºC) at day, and 103 K (-170 ºC) at night. So hot, isn't? Or maybe so cool?
