The earth, the third planet from the sun, is the fifth planet in the solar system; only the gas giants Jupiter, Saturn, Uranus, and Neptune are larger. The Earth is the largest terrestrial planet in the solar system, larger than Mercury, Venus, and Mars. But how big is the earth?
Radius, Diameter, and Perimeter
According to data from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, the radius of the Earth at the equator is 3,963 miles (6,378 kilometers). However, the earth is not a sphere. The rotation of the planet causes it to expand at the equator. The polar radius of the earth is 3,950 miles (6,356 kilometers), a difference of 13 miles (22 kilometers).
According to these measurements, the Earth’s equatorial circumference is approximately 24,901 miles (40,075 kilometers). However, from the polar region to the polar region, the circumference of the earth is only 24,860 miles (40,008 kilometers) in the southern week. The shape of our planet caused by the flattening of the poles is called an oblate. These numbers of 4,444 make Earth only slightly larger than Venus, whose equatorial radius is about 3,761 miles (6,052 kilometers). Mars is much smaller than Earth and Venus, with an equatorial radius of only 3,396 kilometers (2,110 miles).

But Earth and other rocky planets are much smaller than gas giants. For example, Jupiter can contain more than 1,300 Earths. Related

Density, mass and volume
According to NASA data, the density of the Earth is 5,513 g / cm3. Earth is the densest planet in the solar system due to its metallic core and rocky mantle. Jupiter’s mass is 318 times that of Earth, but it is less dense because it is made up mostly of gases like hydrogen.
The mass of the earth is 660 million tons (5.9722 x 1024 kg). Its volume is approximately 260 billion cubic miles (1 trillion cubic kilometers).
The total area of ​​the Earth is approximately 510 million square kilometers (197 million square miles). Approximately 71% of our planet is covered by water and 29% by land. By comparison, the total area of ​​Venus is about 178 million square miles (460 million square kilometers), and the total area of ​​Mars is about 56 million square miles (144 million square kilometers).

The highest point and the lowest point
Mount Everest is the highest place on earth, 29,032 feet (8,849 meters) above sea level, but it is not the highest point on earth, that is, the farthest place from the center of the earth. According to the National Oceanic and Atmospheric Administration (NOAA), this distinction belongs to Chimaborazo in the Ecuadorian Andes. Although Chimaborazo is about 10,000 feet (3,048 m) shorter than Everest (relative to sea level), the mountain is about 6,800 feet (2,073 m) farther in space due to the uplift of the equator.
However, Mount Everest and Chimborazo are still far from the highest mountain in the solar system. For example, the peak that rises from the Rhea Silvia crater on the asteroid Vesta is about 14 miles (22.5 kilometers) high. The huge Olympus volcano on Mars is almost as high as it, 13.6 miles (21.9 kilometers) high, covering an area equivalent to the area of ​​Arizona.
According to the US National Oceanic and Atmospheric Administration, the lowest point on earth is the Challenger Abyss in the Mariana Trench in the Western Pacific. It reaches approximately 11,034 m (36,200 ft) below sea level.
