G'day space lovers! This planet can melt a tin of Vegemite in seconds... But somehow still has ICE?! Welcome to Mercury, mate!br Mercury is smaller than some moons! It's sitting just 58 million km from the Sun That's like having a barbecue... IN the barbecue! 🔥br Here's the kicker: Dayside: 427°C (hot enough to melt lead!) Nightside: -179°C (colder than Antarctica!) Temperature swing? Over 600°C! That's more extreme than any Aussie summer!br But wait, there's more! (classic Aussie TV vibes) One day on Mercury = 176 Earth days So you'd age slower there than a government project! 😂br The absolute madness? This hellish world has POLAR ICE CAPS! Thick layers of ice hiding in shadowy craters Nature's own esky, keeping cool forever!br How's this possible? Mercury's got a massive iron core 42 of the planet vs Earth's measly 19 It's basically a giant metal ball with a thin rocky jacket!br We've sent 3 missions there already And there's SO much more to uncover...
