Mercury, the planet closest to the Sun, resembles a hellish landscape in the cosmos. Without the protection of an atmosphere, it endures temperatures nine times hotter than Earth, reaching up to 400°C, which is enough to melt lead and tin. Here, the daytime heat is infernal, while nighttime plummets to a chilling -163°C, akin to an ice cellar. Such extreme temperature fluctuations make Mercury a planet full of mysteries.
The cycle of day and night on Mercury lasts an astonishing 30 days, meaning it experiences continuous high heat and extreme cold over a single month. These harsh environmental conditions render it impossible for any known life forms to survive here. The sights on Mercury are both terrifying and enigmatic, prompting one to ponder whether this seemingly desolate world conceals even more unsolved mysteries beneath its surface.
