Essential Facts About Planet Earth


Here you will find a listing of essential facts about planet Earth, the home to all of humanity.

The circumference of the Earth at the equator: 24,901.55 miles (40,075.16 kilometers), but, if you measure the earth through the poles the circumference is a bit shorter, 24,859.82 miles (40,008 km). 

The shape of the Earth: The earth is a bit wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).

Human Population of the Earth: 7,245,600,000 (estimated as of May 2015)

World Population Growth: 1.064% - 2014 estimate (this means at the current rate of growth, the earth's population will double in about 68 years)

Countries of the World: 196 (with the addition of South Sudan in 2011 as the world's newest country)

Earth's Diameter at the Equator: 7,926.28 miles (12,756.1 km)

Earth's Diameter at the Poles: 7,899.80 miles (12,713.5 km)

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)

Highest Elevation on Earth: Mt. Everest, Asia: 29,035 feet (8850 m)

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)

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 oblateness of the Earth.

Lowest Elevation on Land: Dead Sea - 1369 feet below sea level (417.27 m)

Deepest Point in the Ocean: Challenger Deep, Mariana Trench, Western Pacific Ocean: 36,070 feet (10,994 m)

Highest Temperature Recorded: 134°F (56.7°C) - Greenland Ranch in Death Valley, California, July 10, 1913

Lowest Temperature Recorded: -128.5°F (-89.2°C) - Vostok, Antarctica, July 21, 1983

Water vs. Land: 70.8% Water, 29.2% Land

Age of the Earth: About 4.55 billion years

Atmosphere Content: 77% nitrogen, 21% oxygen, and traces of argon, carbon dioxide and water

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).

Revolution around Sun: 365.2425 days

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
