The Neo-Babylonian Empire was a period of Mesopotamian history which began in 626 BC and ended in 539 BC. During the preceding three centuries, Babylonia had been ruled by their fellow Akkadian speakers and northern neighbours, Assyria.
In order for a satellite to successfully orbit the Earth, it must travel a horizontal distance of 8000 meters before falling a vertical distance of 5 meters. A horizontally launched projectile falls a vertical distance of 5 meters in its first second of motion.
Depending on the job they have to do, we put satellites into different orbits. Some orbit the Sun, but most orbit the Earth. Three very useful types of orbit are a polar orbit, a geostationary orbit (GEO) and a low Earth orbit (LEO). These satellites are in orbit above the Earth's equator. They stay above the same location on Earth. They are used for telecommunications, television transmission and for navigation. Low Earth orbit (LEO) A satellite has a Low Earth Orbit when it orbits somewhere between 300 and 800 km above the Earth's surface. These satellites only take about 90 minutes to go around the Earth. They are ideal for making observations of the Earth's resources.
