The US has the 2nd largest Exclusive Economic Zone of 11,351,000 km 2 (4,383,000 sq mi). By total area ( water as well as land), the United States is either slightly larger or smaller than the People's Republic of China, making it the world's third or fourth-largest country.
Earth mass. The mass of our planet has been worked out. It is near to 5.9722 × 1024 kg. This was published by the International Astronomical Union in 2009. [1] For short, people write it as or . This symbol is a unit of mass for planets, moons, and other large things in space. Newton's law of universal gravitation was the first step to ...
Map all coordinates using OpenStreetMap. This list of impact structures on Earth contains a selection of the 190 confirmed craters given in the Earth Impact Database as of 2017. [1] [a] To keep the lists manageable, only the largest impact structures within a time period are included. Alphabetical lists for different continents can be found ...

It is the eleventh-most populous country and the second-most populous island country in the world. The population is clustered in urban areas along the coast, plains, and valleys.
The Earth and most of the planets in the Solar System, as well as the Sun and other stars, all generate magnetic fields through the motion of electrically conducting fluids. [53] The Earth's field originates in its core. This is a region of iron alloys extending to about 3400 km (the radius of the Earth is 6370 km).
The Sun is the Solar System's star and by far its most massive component. Its large mass (332,900 Earth masses), which comprises 99.86% of all the mass in the Solar System, produces temperatures and densities in its core high enough to sustain nuclear fusion of hydrogen into helium.
The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of the Solar System. It has an absolute magnitude of +4.83, estimated to be brighter than about 85% of the stars in the Milky Way, most of which are red dwarfs. [32] [33] The Sun is a Population I, or heavy-element-rich, [b] star. [34]
