| The earth travels at a speed of 660,000 miles per hour as it moves through space. |
| The earth is estimated to weigh 6,588,000,000,000,000,000,000,000 tons. |
| The earth's diameter is 13,000 km. |
| The earth is approximately 92,955,820 miles away from the sun. |
| It takes the earth 365.24 days to revolve around the sun. |
| It takes the earth 23.934 hours to rotate on its own axis. |
| If the earth were suddenly flat the water would be 2 miles deep everywhere. |
| Glaciers cover an area on earth equal to the size of South America. |
| The world was once believed to be flat, but it is not flat, and it is also not round. It bulges at the equator and is flattened at its poles. Its shape is an oblate spheroid or a geoid. |
| If you could travel towards the earth's core, the temperature would increase one degree for each 60 feet traveled. |
| The earth is slowing its rotation by about 17 milliseconds every hundred years. At this rate it will take 140 million years before a day is an hour longer (25 hours). |
| The earth also rotates faster in September than it does in March. |
| Earth is the only planet having an atmosphere that contains free oxygen, liquid water and life. |
| Earth's core is made up primarily of nickel and iron, and its mantle is composed of iron and rock. Its core is approximately 4,400 miles wide which is about the same size as Mars. |
| It is believed that the earth's core has a temperature of up to approximately 4,300 degrees Celsius. |
| Some estimates say that there are up to 100 million different species on earth, but only approximately 2 million have been identified. |
| Earth's magnetic field, caused by its rapid rotation and its nickel-iron core, protects the planet from solar wind's effects. |
| Originally people believed that the earth was the center of our universe but Copernicus proved that it was actually the sun. |
| Earth is tilted at approximately 66 degrees. |
| The continent of Asia only covers 30% of earth's land area but it holds 60% of the entire population on the planet. |
| The earth's water is 97% salted, and only 3% fresh. Of the 3% fresh water, 2/3rds is frozen. That means that only 1% of the earth's water is drinkable, but because of pollution and other global water issues, there is much less available for humans to use today. |
