Myths about comets

                                    Myths about comets

Comets are the stars with tails ! They have a head part and also the tail part. The tail is mainly consisted of frozen ice and also dust particles.
They just follow the head part because of the gravity attraction. Comet's orbit will be  elliptical and they may revolve around a star like Sun. Same as planets revolve around Sun .
The Halley comet always come around the orbit of planet earth for every 76 years. Now since ancient time, there are myths regarding comets .  People are scared by the occurrence of these. People think if a comet is visible in sky, then it is surely going to be destruction on our planet earth.
The next  myth is that if the tail of the comet passes through earth's orbit , then there is a sure chance of tsunami. May be it all had happened as a mere coincidence, there is no scientific background for these. It is all just because of the orbit of comet.
