Halley’s comet is the only short-period comet that is clearly visible to the naked eye
Halley’s comet is the most popular of comets. It rotates around the Sun with a period of 74 to 79 years in highly elliptical orbit. During the appearance of the comet in 1835 with the help of spectral analysis it was found that the composition of cometary atmospheres observed molecular bands of CYANOGEN, carbon monoxide and other compounds. So quickly spread rumors about poisoning the earth’s atmosphere hazardous to human health toxic cometary gases.
As predicted by astronomers, may 19, 1910 the Earth “collided” with the tail of Halley’s comet. However, even the most sensitive instruments have not detected any unusual phenomena in the Earth’s atmosphere, which could uniquely associate with this event. So the wave of fear that swept through many countries in may 1910, had under itself no soil.
After passing through the tail of Halley’s comet, the Earth appeared as a kind of probe. It should be noted that the Earth has been repeatedly passed through the tails of comets, and the effect was always the same – no influence on processes in the earth’s atmosphere substance of different tails of comets were not provided.

Comets fascinate the human mind since ancient people first noticed the white tail streaking through the night starry sky. We remember the date when the comet flies past the Earth once a century or even less often and remember all our lives. In the middle ages in Europe, the appearance of comets was often linked to various natural disasters and diseases. In religion, these heavenly bodies also play an important role. For example, in the New Testament, the comet heralded the birth of Christ.
Astronomers find comets also interesting and fascinating space objects, because they are witnesses of great historical events and even carry evidence of them.
The comet is a relatively small object in our solar system, usually having a diameter of several kilometers. Sometimes called “dirty snowballs” because of their component substances. Usually comets are composed of the following four elements:
Ice (water, ammonia, methane, carbon dioxide)
Some organic materials (e.g., resin)
Rocky ground (optional) Continue reading
