Amazing Facts
Earth is the only known planet in the universe to harbor life — so far!
Earth is not a perfect sphere — it bulges slightly at the equator due to its rotation.
About 71% of Earth's surface is covered by water. It's the only planet with liquid water on its surface.
Earth has a powerful magnetic field generated by its liquid iron outer core, which protects us from the Sun's harmful radiation.
Earth's Moon is unusually large for a rocky planet — about 1/4 of Earth's diameter — and stabilizes Earth's axial tilt, giving us stable seasons.
