Exploring Earth’s Motion: Why We Feel Still


πŸŒπŸš€ Are we really standing still?

It feels like we are standing still…
πŸ‘‰ But Earth, the Sun, and our galaxy are all moving very fast!

We are riding on many moving systems at the same time.


1️⃣ Earth Rotating & Orbiting the Sun

🌍 Earth’s motion

πŸ”„ Earth spinning (rotation)

  • Earth spins once every 24 hours
  • Speed at the equator: about 1,670 km/hour

🧠 This spin gives us day and night


β˜€οΈ Earth going around the Sun (orbit)

  • Earth travels around the Sun once every 365 days
  • Speed: about 107,000 km/hour

🧠 This movement gives us years and seasons


2️⃣ β˜€οΈ The Sun Moving in the Galaxy

🌌 Galactic orbit

  • Our Sun is not standing still
  • It moves around the center of the Milky Way galaxy
  • Speed: about 828,000 km/hour
  • Takes about 225 million years to go around once!

🧠 Dinosaurs lived and died during just ONE galactic orbit!


3️⃣ 🌌 The Galaxy Moving Through Space

πŸš€ Milky Way’s journey

  • Our galaxy is also moving through space
  • It is heading toward a group of galaxies
  • Speed: over 2 million km/hour

🧠 The whole galaxy is like a giant spaceship!


🧠 Why don’t we feel this motion?

  • The movement is smooth and constant
  • Just like sitting in a flying airplane ✈️
  • You only feel motion when speed changes suddenly

πŸ“Š Simple summary table

MotionSpeed
Earth spinning~1,670 km/h
Earth orbiting Sun~107,000 km/h
Sun orbiting galaxy~828,000 km/h
Galaxy moving in space~2,000,000+ km/h

🌟 Easy way to remember

You are standing on Earth
Earth rides the Sun
Sun rides the Galaxy
Galaxy rides the Universe πŸš€
