The Earth has a diameter of 7,926.3 miles at the equator, and its circumference, or the distance around the earth at the equator, is 24,901.55 miles. plates which slowly move along the surface of the planet. Earth, our home planet, is a world unlike any other. In the last two centuries, humans have added enough greenhouse gases to the atmosphere to raise Earth's average temperature by 1.8 degrees Fahrenheit. temperature, and + Equal Employment Opportunity Data Posted Pursuant to the No Fear Act

orbits the Earth. This axis of rotation is tilted 23.4 degrees away from the plane of Earth's orbit around the sun, giving us seasons. aerodynamic drag The Earth is widest at the equator. When plates of continental crust collide, mountain ranges such as the Himalaya are pushed toward the skies. With a radius of 3,959 miles, Earth is the fifth largest planet in our solar system, and it's the only one known for sure to have liquid water on its surface. The Like Venus and Mars, Earth has mountains, valleys, and volcanoes. These bodies of water contain 97 percent of Earth's volcanoes and the mid-ocean ridge, a massive mountain range more than 40,000 miles long. Thanks to instruments such as NASA's Kepler Space Telescope, astronomers have found more than 3,800 planets orbiting other stars, some of which are about the size of Earth, and a handful of which orbit in the zones around their stars that are just the right temperature to be potentially habitable. According to Macrobious, Eratosthenes made the diameter of the Sun to be about 27 times that of the Earth.

Its diameter (the distance from one side to the other through Earth's center) is … Earth orbits the sun once every 365.25 days.

But due to the field's structure, some particles get funneled to Earth's Poles and collide with our atmosphere, yielding aurorae, the natural fireworks show known by some as the northern lights.

We also enjoy protection from Earth's magnetic field, generated by our planet's rotation and its iron-nickel core. This is the diameter of the Earth measured from one side of the Earth, passing through the center. Much like a greenhouse, this blanket of gases absorbs and retains heat. But for all that our atmosphere does, it's surprisingly thin. Many volcanoes form as seafloor crust smashes into and slides beneath continental crust.

Over time, Earth's interior—which is made mostly of silicate rocks and metals—differentiated into four layers. On two specific dates each year—called the equinoxes—both hemispheres get illuminated equally. Rocket Home In the spring and fall, each hemisphere receives similar amounts of light.

The diameter of the Earth at the poles is 7,899.8 miles. Though we can't feel it, Earth zooms through its orbit at an average velocity of 18.5 miles a second.

composed of 78% nitrogen, 21% oxygen, and traces of other gases including Earth 101 Earth is the only planet known to maintain life. On land, the continental crust is an average of 19 miles thick, but the oceanic crust that forms the seafloor is thinner—about three miles thick—and denser. The resulting on another page. Related Sites: The diameter of Earth is about 2.6 times that of the smallest planet, Mercury, but Jupiter has a diameter that is more than 28.5 times that of Mercury.

The Earth's diameter is larger than that of Mercury at 3,032 miles, Mars at 4,222 miles and Venus at 7,521 miles. with respect to the Sun (23 hrs 56 min with respect to the stars). At the same time, telescopes are gazing outward to find other Earths.

After Earth's, the next two largest diameters belong to Neptune at 30,778 miles and Uranus at 31,763 miles. Moon, The 2020 National Geographic Partners, LLC. above the Earth's surface. As these plates collide, tear apart, or slide past each other, they give rise to our very active geology. Saturn has the second-largest diameter at 74,898 miles, and Jupiter has the largest at 88,846 miles. from the Sun and provides a convenient way for navigating on the surface. Whichever hemisphere is tilted closer to the sun experiences summer, while the hemisphere tilted away gets winter. It is the third planet from the Sun and orbits Will 5G Impact Our Cell Phone Plans (or Our Health?! Earth's atmosphere is 78 percent nitrogen, 21 percent oxygen, and one percent other gases such as carbon dioxide, water vapor, and argon.
