MIRA STAR (COMET) 

Comets are not really stars. An Asteroid or a Star which moves fast that creates a tail like structure makes COMETS. But, true comets are also lies in our UNIVERSE. Let's see about it.

OMICRON CETI:

Mira (or) Omicron Ceti is a big red star is located at a distance of 420 lightyears from our Earth. This Mira star is much bigger than our Sun. It was discover by a famous scientist DAVID FEROCIOUS in 1600's. He was researching to Jupiter, He found a bright star called Mira. He continuously researching to Jupiter with reference to that star. He noted that the star suddenly decreases its brightness continuously. and at the end of 10 months is disappears completely. After 6 years, Jonen a scientist found that disappearing star. Then, he concluded that there a PULSATING (disappearing) stars also lies in our Universe.

MIRA-A:

Then researches continues to that Mira, It is at a distance of 420 light years from the Earth. It is a RED DWARF GIANT. and it is 570 times bigger than our Sun. But, it is just 1.5 times bigger than our Sun. This is because, it attains it's last stage. Scientists guess the age of the star, that is approximately 600 crore years.

Mira is a Latin word, which means AMAZING, ASTONISHING. and we know that this star increases and decreases it's brightness every 10 months. This type of star changes its size to change it's brightness, while increasing or decreasing a huge number of particles comes out of the star.

PULSATING STAR:

Every 10 years once, it losses around 10times mass of the Earth as particles or energy. If we apply a ULTRA-VIOLET filter via a telescope we can see the tail of a star. Mira has a tail of length around 13 light years longer. Mira is not single in space, It has an other star which is named as MIRA-B. It is a WHITE DWARF STAR and present at a distance of 70 astronomical to MIRA-A. MIRA-B revolves around MIRA-A. It takes around 400 years to complete one rotation. MIRA STAR begins to end its life. 

THE CONCLUSION:

MIRA is truly a star which has tail which is referred as a COMET. If you have a time to see space then see it. It completely gives you a refreshment.
