Halley's Comet


Halley's Comet or Comet Halley, officially designated 1P/Halley, is a short-period comet visible from the earth every 75-76 years. Halley is the only known short-period comet that is regularly visible to the naked eye from the earth, and the only naked-eye comet that might appear twice in a human lifetime. Halley last appeared in the inner part in the solar system in 1986 and will next appear in mid-2061 to 2062. 

Halley's return to the inner solar system has been observed and recorded by the astronomers since 240BC. Clear records of the comet's appearance were made by Chinese, Babylonian and medieval European chronicles, but, at those times were not recognised as appearances of the same object. The comet's periodicity was first determined in 1705 by English astronomer Edmond Halley, after whom it is now named.

The Nile would flood each year, coating the land on either side of the river with, thick black mud. This mud was ideal for growing crops. In short, Nile provides the ancient Egyptians with fertile land which helped them to grow their crops and raise their animals. Gradually, two separate kingdoms, ruled by different kings, developed along Nile River. The kingdom in Upper Egypt-the area on both sides of the Nile- was known as the White Crown, and the kingdom in lower Egypt was called the Red Crown. Around 3200 BC, the two were united ...
