Mercury, the closest planet to the Sun, is a world of extreme contrasts. The side facing the Sun experiences scorching temperatures, reaching up to 800°F (427°C), while the side in darkness plunges to a freezing -330°F (-201°C). This tiny planet, despite being so close to the Sun, has no atmosphere to retain heat, leading to these dramatic temperature differences. Share this with your friends who can handle the heat or embrace the cold! ️❄️
