The Size of the Earth, and the Continuing Enlargement of the Size Debate

Jakarta, CNN Indonesia

How wide the size of the Earth is still a big question for some people. Moreover, some reports say the size of the Earth is getting bigger.

Earth is the third planet from the Sun, as well as the fifth largest of the eight planets in the solar system. Earth is called the largest terrestrial planet in the inner solar system, larger than Mercury, Venus and Mars.

How wide is the Earth?

According to NASA’s Goddard Space Flight Center in Greenbelt, Maryland, Earth’s diameter at the equator measures 6,378 kilometers. So the Earth is called not completely round. The planet’s rotation causes it to bulge at the equator.

Using these measurements, Earth’s equatorial circumference is about 40,075 kilometers. However, from pole to pole – the meridional circumference – the Earth is only 40,0008 kilometers. The shape of our planet, caused by the alignment of the poles, is called an oblate spheroid.

According to NASA, Earth’s density is 5.513 grams per cubic centimeter. Earth is the densest planet in the solar system because it has a metal core and a rocky mantle.

Jupiter, on the other hand, has a less dense structure because it consists mostly of gases such as hydrogen.

The mass of the Earth is 6.6 sextillion tons. Its volume is about 260 billion cubic miles or 1 trillion cubic kilometers. The total surface area of ​​the Earth is about 510 million square kilometers.

About 71 percent of our planet is covered by water, while 29 percent by land. By comparison, the total surface area of ​​Venus is about 460 million square kilometers, and Mars about 144 million square kilometers.

Mount Everest is the highest place on Earth above sea level at 8,849 meters. But it is not the highest point on Earth or the most distant place from the center of the Earth.

According to the US National Oceanic and Atmospheric Administration (NOAA), the highest position on Earth is Mount Chimaborazo in Ecuador’s Andes Mountains.

Although Chimaborazo is 3,048 meters shorter than Everest, it is 2,073 meters farther into space due to the equatorial bulge. Space.

In addition, the lowest point on Earth according to NOAA is the Challenger Deep in the Mariana Trench in the western Pacific Ocean. The location is about 11,034 meters below sea level.
