Interesting Facts About Earth
- The earth is actually not an exactly sphere. It is a bit flattened at the poles and bulge around the equator.
- At the equator, you would weigh less than if standing at one of the poles.
- The Earth is about 4.54 billion years old.
- The ground you’re walking on is recycled. Earth’s rock cycle transforms igneous rocks to sedimentary rocks to metamorphic rocks and back again.
- Earth may once have had two moons. A teensy second moon — spanning about 750 miles (1,200 km) wide — may have orbited Earth before it catastrophically slammed into the other one.
- Some scientists claim Earth has two moons currently.
- The Earth is approximately 93 million miles (150 million kilometers) from the sun. At this distance, it takes about 8 minutes and 19 seconds for sunlight to reach our planet.
- Many researchers think some large object crashed into Earth long ago, and the resulting debris coalesced to form our moon.
- The Earth’s continents are thought to have collided to become supercontinents and broken apart again several times in Earth’s 4.5 billion year history.
- There are almost surely more planets like ours. Space scientists have found evidence of Earth-like planets orbiting distant stars, including an alien planet called Kepler 22-b circling in the habitable zone of a star much like ours.
