Earth Theia = 🌕⁠ ⁠ Billions of years ago, Earth wasn’t alone. A rogue planet the size of Mars — named Theia — slammed into our young world in a violent, fiery collision. 🌍💥 ⁠ ⁠ From that single, catastrophic moment, something incredible happened: our Moon may have formed in just a few hours. Not over millennia, not even months, just hours! ⏱️ ⁠ ⁠ 🚀 NASA-backed supercomputer simulations suggest the Moon didn’t slowly build from debris — it was born almost instantly, forged from molten chunks

4.5 billion years ago, a planet-sized body named Theia struck the young Earth — an impact so powerful it melted both worlds and gave birth to our Moon. This collision changed everything: Earth’s tilt, tides, and even the rhythm of life. But what would our world look like without it? #space #earth #moon #nasa #science | ScienceExplained
