Mercury's Heat and Cold

MERCURY · the biggest temperature swing

DAY up to 430 °CNIGHT down to minus 180 °C

No planet swings harder: Mercury's day side bakes at 430 degrees while its night side, with almost no atmosphere to hold the warmth, plunges below minus 180. That is a 600 degree difference between facing the Sun and facing away. Future visitors would not fight the heat or the cold so much as the line between them.
