- At night however, without an atmosphere to hold the heat in, the temperatures plummet, dropping to -180 Degrees Celsius.
- Mercury has a very low surface gravity.
- Mercury has no atmosphere which means there is no wind or weather to speak of.
- There is also no water on the surface of Mercury, it is possible however that there could be water underneath the surface.
