7926 miles
With an equatorial diameter of 7926 miles (12,760 kilometers), Earth is the biggest of the terrestrial planets and the fifth largest planet in our solar system.about 12,756 kilometers
Its diameter (the distance from one side to the other through Earth's center) is 7,926 miles (about 12,756 kilometers). Earth is slightly smaller when measured between the North and South Poles which gives a diameter of 7,907 miles (12,725 kilometers).Therefore, the diameter of Earth through its center is 7,926 miles (12,756 km). Again, because of the equatorial bulge, the planet's diameter is slightly smaller when measured from pole to pole, where it is about 7,900 miles (12,712 km). The equatorial circumference of Earth is 24,901 miles (40,075 km).
Is the Earth getting bigger : Measurements with modern high-precision geodetic techniques and modeling of the measurements by the horizontal motions of independent rigid plates at the surface of a globe of free radius, were proposed as evidence that Earth is not currently increasing in size to within a measurement accuracy of 0.2 mm per year.
How is Earth so big
The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.
Is Earth is big or small : Earth is a big place. If you could drive around the entire planet, it would take more than sixteen days of non-stop driving at highway speeds. But, compared to some of the planets in our solar system, it's pretty small.
The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately 40000 km.
The Kármán line is the altitude where space begins. It is 100 km (about 62 miles) high. It commonly represents the border between the Earth's atmosphere and outer space. This definition is accepted by the Fédération Aéronautique Internationale (FAI).
Why is Russia so big on the map
Its immense size can be attributed to a combination of historical, geographic, and political factors. As the successor to the Soviet Union, Russia inherited vast territories that were once part of this powerful empire.He estimated that the world could support 13.4 billion people. Estimates in the last half of the 20th century ranged from less than 1 billion to more than 1,000 billion.Finally, the most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.
So how long does Earth have until the planet is swallowed by the sun Expected time of death: several billion years from now. But life on Earth will end much, much sooner than that. Earth will become unlivable for most organisms in about 1.3 billion years due to the sun's natural evolution, experts told Live Science.
Who named Earth : We have no idea who first penned the name Earth for our planet, nor do we know exactly when the name came about. We do know that the name Earth has been in use for at least a millennia. The only other fact we know about Earth's name is that it comes from the German word "erde" which translates to "the ground."
Is the Earth 4.6 billion years old : It is widely accepted by both geologists and astronomers that Earth is roughly 4.6 billion years old. This age has been obtained from the isotopic analysis of many meteorites as well as of soil and rock samples from the Moon by such dating methods as rubidium–strontium and uranium–lead.

Many scientists think that the next ice age will reach its peak in about 80,000 years [source: Revkin]. So, in 50,000 years, the planet will likely be a much colder place, with ice sheets approaching areas as far south as New York City.Originally Answered: What would happen if the Earth were 1 km close to the sun If it's one KM close to sun: Earth will turn to gases. If it's one KM closer than current position: Absolutely nothing. Distance between earth and sun wobbles far more than that because earth's orbit is not perfectly circular.
Why is 1 hour in space 7 years on Earth : Terrestrial seconds seven years in space are equal to just one hour on Earth.
