Why is Pluto not a planet? What to know about the planetary debate

Orhun's Astronomy Page on Instagram: "🌍💥 What if a Pluto-sized asteroid hit Earth? Pluto has a diameter of about 2,377 km — that’s nearly one-sixth of Earth’s size. If such a giant object slammed into our planet, the result would be planetary destruction. The impact would release more energy than all nuclear weapons combined by billions of times. Earth’s crust would melt, oceans would vaporize, and the atmosphere would be blown away. In short: our planet would cease to exist as we know it. 📹
