Earth, our beautiful home planet, is the only astronomical object to accommodate life as we know it. Scientists believe Earth was formed approximately 4.5 billion years ago. It is the fifth-largest planet in our solar system. Its equatorial diameter is about the third-closest planet to the sun. The distance from Earth to the sun is roughly 149,600,000 kilometers. It takes 365.3 days for Earth to orbit the sun, and 24 hours to rotate on its axis. The surface temperature ranges from -88 to 58°C. Nearly 70 percent of Earth's surface is covered by ocean, which has an average depth of about 4 kilometers. In 2015 it was estimated that 7.3 billion humans are living on Earth.

Did you know that the spacesuit astronauts wear while in outer space is formally called an Extravehicular Mobility Unit, or EMU? ‘Extravehicular’ means outside of a spacecraft, and '' means that the astronaut can move around in the suit, independent of the . An EMU is not simply a set of clothes. The suit provides life support and environmental protection for the astronaut during planetary exploration or . For example, spacesuits protect astronauts from extreme temperature change, which can go as cold as , or as hot as 120 degrees Celsius. Spacesuits also supply astronauts with to breathe and water to drink during spacewalks. They protect astronauts against fast-moving space dust particles, , and bright sunlight.
