Earth Size report

Earth is the third planet from the sun and the only celestial body known to give birth to live. Approximately 29.2% of the Earth's surface is land composed of continents and islands. The remaining 70.8% is covered by water, most of which is covered by oceans, bays, and other salty water bodies, lakes, rivers, and other freshwater, which form the hydrosphere. The polar regions are covered by ice. The Earth's outer layer is divided into several rigid tectonic plates, which have migrated on the surface over millions of years, while the interior remains active.

The Earth's atmosphere is mainly composed of nitrogen and oxygen. Tropical regions receive more solar energy than polar regions and are redistributed through atmospheric and ocean circulation. Greenhouse gases also play an essential role in regulating surface temperature. The climate is determined by latitude and factors such as altitude and proximity to the area and the ocean.

The gravity of the Earth interacts with other objects in space, especially the moon, which is the only natural satellite of the planet. The gravitational interaction between the Earth and the moon causes tides. It takes about 365.25 days for the Earth to revolve around the sun. The rotation of the Earth gives the seasons to us. Let's learn more about the Earth's size by reading the following article.

Earth Size And Descriptions

The Earth is the homeland where humankind lives together, and humankind has only one Earth. It was formed about 4.5 to 4.6 billion years ago and is the only planet to sustain life. Earth, the third planet from the sun, is the fifth-largest planet in the solar system; only Jupiter, Saturn, Uranus, and Neptune are bigger. Earth is the largest terrestrial planet in the inner solar system, bigger than Mercury, Venus, and Mars. But do you know how big exactly Earth is?

Radius, Diameter, And Circumference

• The radius of Earth at the equator is 3,963 miles (6,378 kilometers). However, Earth is not quite a sphere. The planet's rotation causes it to bulge at the equator.
• Earth's polar radius is 3,950 miles (6,356 km) — a difference of 13 miles (22 km). Our planet's shape, caused by the flattening at the poles, is called an oblate spheroid.
• The equatorial circumference of Earth is about 24,901 miles (40,075 km). However, from pole to pole, the meridional circumference, Earth is only 24,860 miles (40,008 km) around.

Mass And Volume

• Earth is the densest planet in the solar system because of its metallic core and rocky mantle. Earth's density is about 5.513 grams per cubic centimeter.
• Earth's mass is 6.6 sextillion tons (5.9722 x 1024 kilograms). Its volume is about 260 billion cubic miles (1 trillion cubic kilometers).
• Earth's total surface area is about 197 million square miles (510 million square km). About 71% of our planet is covered by water and 29% by land.
  

Orbit and Rotation

As Earth orbits the sun, it completes one rotation every 23.9 hours. It takes 365.25 days to complete one trip around the sun. People count one year as 365 days in our calendar system to facilitate calculations. Earth's axis of rotation is tilted 23.4 degrees concerning the plane of Earth's orbit around the sun.

Sun Size vs. Earth Size

The sun lies at the heart of the solar system, where it is 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 Earth could fit inside the sun. The average distance between the Earth and the sun is 92,955,820 miles (149,597,890 kilometers).

Moon Size vs. Earth Size

Earth is the only planet that has a single moon. Our Moon is the brightest and most familiar object in the night sky. The Moon stabilizes our planet's wobble, which has made the climate less variable over thousands of years. With a radius of 1,080 miles (1,738 kilometers), the Moon becomes the fifth largest Moon in the solar system. Earth's Moon has a diameter of around 3.474 km / 2.158 mi. The Earth is 81 times heavier than the Moon in comparison to Earth. The Moon is about one-quarter the size of Earth, and it would take around 50 moons to fill the Earth. The Moon is an average of 238,855 miles (384,400 kilometers) away from Earth.
