Average Distance from the Earth to the Sun: 93,020,000 miles    (149,669,180 km)
Average Distance from the Earth to the Moon: 238,857 miles (384,403.1 km)
Earth's Circumference at the Equator: 24,901.55 miles (40,075.16 km)
Earth's Circumference Between the North and South Poles: 24,859.82 miles (40,008 km)
Earth's Diameter at the Equator: 7,926.28 miles (12,756.1 km)

1. Earth's Diameter at the Poles: 7,899.80 miles (12,713.5 km)
2. Water vs. Land: 70.8% Water, 29.2% Land
3. Atmosphere Content: 77% nitrogen, 21% oxygen, and traces of argon, carbon dioxide and water
4. Chemical Composition of the Earth: 34.6% Iron, 29.5% Oxygen, 15.2% Silicon, 12.7% Magnesium, 2.4% Nickel, 1.9% Sulfur, and 0.05% Titanium
5. Rotation on Axis: 23 hours and 56 minutes and 04.09053 seconds. But, it takes an additional four minutes for the earth to revolve to the same position as the day before relative to the sun (i.e. 24 hours).
6. Highest Elevation on Earth - Mt. Everest, Asia: 29,035 feet (8850 m)
7. Tallest Mountain on Earth from Base to Peak - Mauna Kea, Hawaii: 33,480 feet (rising to 13,796 feet above sea level) (10204 m; 4205 m)
8. Point Farthest From the Center of the Earth - The peak of the volcano Chimborazo in Ecuador at 20,561 feet (6267 m) is farthest from the center of the earth due to its location near the equator and the oblations of the Earth.
9. Lowest Elevation on Land - Dead Sea: 1369 feet below sea level (417.27 m)
10. Deepest Point in the Ocean - Challenger Deep, Mariana Trench, Western Pacific Ocean: 35,840 feet (10924 m)
11. Highest Temperature Recorded: 135.8°F - Al Aziziyah, Libya, September 13, 1922 (57.7°C)
12. Lowest Temperature Recorded: -128.5°F - Vostok, Antarctica, July 21, 1983 (-89.2°C)
