Mercury, being the closest planet to the Sun in our solar system, experiences extreme temperature variations on its surface. During the daytime, temperatures on Mercury can reach scorching levels, exceeding 400 degrees Celsius (750 degrees Fahrenheit). However, due to the lack of a substantial atmosphere to trap and distribute heat, temperatures on Mercury drop drastically during the nighttime, reaching extremely low temperatures of around -180 degrees Celsius (-290 degrees Fahrenheit).
Given these extreme temperature differences, it is challenging to define a point on Mercury's surface where the temperature can be considered "normal" in comparison to our familiar temperature ranges on Earth. The conditions on Mercury are inhospitable for life as we know it.
Nevertheless, certain regions near the poles of Mercury experience more moderate temperature fluctuations due to the unique characteristics of their topography. In these polar regions, there are areas within craters where the Sun's rays never directly reach the surface, resulting in permanently shadowed regions. These shadowed areas can have relatively stable temperatures, which are closer to what we might consider "normal" in comparison to the rest of the planet. However, even in these regions, the temperatures remain extremely cold, well below freezing.
In summary, while there are regions on Mercury's surface, particularly in polar areas, that experience more stable temperatures compared to other parts of the planet, the concept of a "normal" temperature on Mercury is still significantly different from what we would consider normal on Earth.
