How wide is the Earth?
As a result, the latest measurements indicate that the Earth has an equatorial diameter of 12,756 km (7926 mi), and a polar diameter of 12713.6 km (7899.86 mi). In short, objects located along the equator are about 21 km further away from the center of the Earth (geocenter) than objects located at the poles.
Who named the planet Earth?
The answer is, we don't know. The name "Earth" is derived from both English and German words, 'eor(th)e/ertha' and 'erde', respectively, which mean ground. But, the handle's creator is unknown. One interesting fact about its name: Earth is the only planet that wasn't named after a Greek or Roman god or goddess.
How fast is the Earth spinning?
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.
How many Earths can fit in the sun?
If you divide the volume of the sun by the volume of the Earth, you get that roughly 1.3 million Earths can fit inside the sun.
What makes planet Earth a house for a living organism?
Part of Hall of Planet Earth. What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
How old is the Earth?
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.
Is the sun bigger than Earth?
The sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8% of the solar system's mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
How cold is the Moon?
The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius), at night, to 224 degrees Fahrenheit (106 degrees Celsius) during the day.
Is Australia wider than Moon's diameter?
Although the Moon is about as wide as Australia, it is actually much bigger when you think in terms of surface area. ... The land area of Australia is some 7.69 million square kilometers. By contrast, the surface area of the Moon is 37.94 million square kilometres, close to five times the area of Australia.
Who was Gaia first child?
According to Hesiod, Gaia conceived further offspring with her son, Uranus, first the giant one-eyed Cyclopes: Brontes ("Thunder"), Steropes ("Lightning"), and Arges ("Bright"); then the Hecatonchires: Cottus, Briareos, and Gyges, each with a hundred arms and fifty heads.
