There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface. It is important to understand the difference between rotations and revolutions. When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution. There are two types of orbits: closed (periodic) orbits, and open (escape) orbits. Circular and elliptical orbits are closed.

Paleolithic Period or Old Stone Age; the earliest period of human development, last until approx 8000 BC. The Paleolithic Period is divided into two eras: the Lower Paleolithic (to 40,000 BC) and the Upper Paleolithic (40,000–8000 BC). During the Paleolithic, hominins grouped together in small societies such as bands, and subsisted by gathering plants and fishing, hunting or scavenging wild animals. The Paleolithic is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools.

History (from the Greek ἱστορία, meaning ‘a learning or knowing by inquiry’) can be broadly taken to indicate the past in general but is usually defined as the study of the past from the point at which there were written sources onwards.
There are obstacles that make it so we do not have a crystal clear, uninterrupted view of the past. Firstly, we have to remember that everyone – not just us, but also people throughout history – is shaped by their upbringing and the societies and times they live in, and we need to be careful not to stick our own labels and values onto past periods. Secondly, our view of the past is made up from the total of things that somehow happened to survive the test of time, which is due to coincidences and decisions made by people before our time. So, we only get a fragmentary, distorted view; it is like trying to complete a puzzle with a lot of oddly shaped and missing pieces.
