Live Earth View Right Now – NASA studies our planet more than anyone else. We fly 26 missions into orbit and sponsor hundreds of research programs and studies each year. We observe the planet’s oceans, land, ice and atmosphere, and measure how changes in one affect the others. We are developing new ways to observe and study Earth’s interconnected systems and building long-term data records of how our planet is evolving. The agency freely shares this unique knowledge and collaborates with organizations around the world.

Earth: Facts About The Blue Planet

With a radius of 3,959 miles, Earth is the fifth largest planet in our solar system, and the only one guaranteed to have liquid water on its surface. Earth is also unique when it comes to nicknames. Every other planet in the solar system was named after a Greek or Roman god, but for at least a thousand years, some cultures have described our world using the Germanic word “Jord,” which means “Earth.”

The Earth orbits the Sun every 365.25 days. Since our calendar years only have 365 days, we add an extra leap day every four years to account for the difference.

Although we can’t feel it, the Earth zooms through its orbit at an average speed of 18.5 kilometers per second. In this orbit, our planet is on average 93 million kilometers from the Sun, the distance that light takes about eight minutes to travel. Astronomers define this distance as an astronomical unit (AU), which serves as a practical cosmic measure.

The Earth rotates on its axis every 23.9 hours, defining day and night for surface dwellers. This axis of rotation is tilted 23.4 degrees from the plane of the Earth’s orbit around the Sun, giving rise to the seasons. The hemisphere closer to the sun experiences summer, and the hemisphere tilted away experiences winter. In spring and autumn, each hemisphere receives a similar amount of light. Every year on two specific dates – called the equinoxes – the two hemispheres light up equally.

About 4.5 billion years ago, gravity forced the Earth to form a disk of gas and dust surrounding our young Sun. Over time, the interior of the Earth – which is mainly composed of silicate rocks and metals – was divided into four layers.

At the heart of the planet is the inner core, a solid sphere of iron and nickel 759 kilometers across and as hot as 9,800 degrees Fahrenheit. The inner core is surrounded by the outer core, a 1,400 kilometer thick band of iron and nickel fluids. Behind the outer core is the mantle, a 1,800 kilometer thick layer of viscous molten rock on which the Earth’s outermost layer, the crust, rests. On land, the continental crust has an average thickness of 19 kilometers, but the oceanic crust that forms the ocean floor is thinner—about three kilometers thick—and denser.

Like Venus and Mars, Earth has mountains, valleys, and volcanoes. But unlike its rocky siblings, nearly 70% of Earth’s surface is covered by oceans of liquid water that average 2.5 kilometers deep. 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.

The Earth’s crust and upper mantle are divided into massive plates that grind against each other in slow motion. When these plates collide, tear, or slide past each other, they create our very active geology. Earthquakes rumble as these plates hang and slide next to each other. Many volcanoes are formed when oceanic crust is crushed under continental crust and slides beneath it. When continental crust plates collide, mountain ranges like the Himalayas are pushed skyward.

Earth’s atmosphere is made up of 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases such as carbon dioxide, water vapor, and argon. Like a greenhouse, this blanket of gases absorbs and retains heat. On average, the surface temperature of the Earth is about 57 degrees Fahrenheit; without our atmosphere it would be zero degrees. Over the past two centuries, humans have added enough greenhouse gases to the atmosphere to raise Earth’s average temperature by 1.8 degrees Fahrenheit. This additional heat has changed Earth’s weather patterns in a number of ways.

The atmosphere not only sustains life on Earth, it also protects it: it’s thick enough to burn up many meteorites before impact due to friction, and its gases—like ozone—block DNA-damaging ultraviolet light from reaching the surface. But in everything our atmosphere does, it is surprisingly thin. Ninety percent of Earth’s atmosphere is within 10 kilometers of the planet’s surface.

We also enjoy the protection of Earth’s magnetic field, created by the planet’s rotation and its iron-nickel core. This teardrop-shaped field shields the Earth from high-energy particles sent to us from the Sun and elsewhere in the cosmos. However, due to the structure of the field, some particles are carried to the Earth’s poles and collide with our atmosphere, creating the aurora borealis, a natural fireworks display known to some as the northern lights.

Earth is the planet we have the best chance of understanding in detail; it helps us see how other rocky planets behave, even those orbiting distant stars. As a result, scientists are increasingly monitoring the Earth from space. NASA alone has dozens of missions aimed at unraveling the mysteries of the planet.

At the same time, telescopes are looking outward to find the other Earth. Thanks to instruments like NASA’s Kepler space telescope, astronomers have discovered more than 3,800 planets orbiting other stars, some of them Earth-sized and a few that closely orbit their stars. so that the temperature is potentially livable. Other missions, such as the Transiting Exoplanet Survey Satellite, are poised to find even more.
