Mercury is unlike any other planet due to its extreme temperatures, close proximity to the Sun, and slow rotation. Scientists study Mercury to understand planetary formation and how the Sun affects planets over time.
Mercury’s surface is covered in craters, similar to the Moon, due to constant asteroid impacts. Its thin atmosphere cannot retain heat, leading to extreme temperature shifts.
