The earth passed through the tail of Halley’s comet
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.
Astronomers and many inhabitants of the Earth vnimatelnogo behind all the changes taking place in the head and tail of Halley’s comet. For the entire period of observations was obtained over a thousand of its astrogation, more than a hundred spectrograms, many hundreds of drawings of the comet and the large number of definitions of its Equatorial coordinates at different points in time.
All this wealth of material allowed to investigate in detail the nature of the motion of the comet in its orbit, to study the types, structural features, the chemical composition of its head and tail, as well as a number of other physical parameters of the comet’s nucleus and the surrounding atmosphere. Benefit even artists. And in Europe, and in Russia, several artists depicted the celestial object is clearly visible almost the entire month with the naked eye.
Halley’s comet is the only short-period comet that is clearly visible to the naked eye. The last perihelion was in February 1986; the following experts estimate will be in mid 2061.
