ππ Are we really standing still?
It feels like we are standing stillβ¦
π But Earth, the Sun, and our galaxy are all moving very fast!
We are riding on many moving systems at the same time.
1οΈβ£ Earth Rotating & Orbiting the Sun
π Earthβs motion
π Earth spinning (rotation)
- Earth spins once every 24 hours
- Speed at the equator: about 1,670 km/hour
π§ This spin gives us day and night
βοΈ Earth going around the Sun (orbit)
- Earth travels around the Sun once every 365 days
- Speed: about 107,000 km/hour
π§ This movement gives us years and seasons
2οΈβ£ βοΈ The Sun Moving in the Galaxy
π 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!
π§ Dinosaurs lived and died during just ONE galactic orbit!
3οΈβ£ π The Galaxy Moving Through Space
π Milky Wayβs journey
- Our galaxy is also moving through space
- It is heading toward a group of galaxies
- Speed: over 2 million km/hour
π§ The whole galaxy is like a giant spaceship!
π§ Why donβt we feel this motion?
- The movement is smooth and constant
- Just like sitting in a flying airplane βοΈ
- You only feel motion when speed changes suddenly
π Simple summary table
| Motion | Speed |
|---|---|
| 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 |
π Easy way to remember
You are standing on Earth
Earth rides the Sun
Sun rides the Galaxy
Galaxy rides the Universe π
