Planet

A planet, is a extraterrestrial body orbiting a star or stellar remnant that is massive adequate to be rounded by its own gravity, not massive enough to cause thermonuclear fusion in its core, and has cleared its neighbouring region of planetesimals

After stars and stellar remnants, planets are a few of the most massive objects known to man. They play an important part in the structure of planetary systems, and are also considered, along with large moons, the most feasible environment for life. Thus planetary science is crucial not only to comprehend the structure of the universe, but also to better understand the development of life, and to aid the search for extraterrestrial intelligence. Additionally, the planets visible from Earth have played a vital role in the shaping of human culture, religion and philosophy in abundant civilisations. Even today, many people continue to believe true the movement of the planets affects their lives, all though such a causation is discarded by the scientific community.

History of Egypt

The history of Egypt is the fastest constant history, as a unified state, of every country in the world. The Nile valley forms a natural geographic unit, surrounded to the east and west by deserts, to the north by the sea and to the south by the Cataracts of the Nile. They require having a single ability to manage the waters of the Nile led to the making of the world's first state in Egypt in about 3000 BC. Egypt's peculiar geography made it a hard country to attack, which is why Pharaonic Egypt was for so long an sovereign and self-contained state.

Once Egypt did yield to foreign rule, yet, it proved unable to escape from it, and for 2,400 years Egypt was governed by foreigners. (The Hyksos were among the first foreign rulers of Egypt, but the ancient Egyptians regained organize of their country after the Hykso period.)
