textbook humor:

"If you stood in direct sunlight on Mercury, you would hear your spacesuit's cooling system cranking up to top speed as it tried to keep you cool. Daytime temperatures can exceed 800F.... If you stepped into shadow on Mercury or took a walk at night, with no atmosphere to distribute heat, your spacesuit heaters would strufflt to keep you warm. The surface can cool to -280F. Nights on Mercury are bitter cold. Don't go to Mercury in a cheap spacesuit."
