Comet Garradd C/2009 P1

Comet Garradd C/2009 P1

Comets come from a place called the sphere cometary remnant of the past and distant reservoir of matter that surrounds the solar system. Comet Garradd C/2009 P1, is a comet that was discovered August 13, 2009, by astronomer Gordon Garradd on a photograph taken at the observatory of Spring Sinding Australia.
In August 2011, the comet was Garradd in the constellation Sagittarius, alongside the globular cluster Messier 71. She traveled to more than 200 million kilometers from Earth. On the video we have seen passing near the cluster M 71 which is him, much further, to 13,000 light years. Comet Garradd starred in the summer of 2011. On February 4, 2012, the comet is back, this time deploying, a dust tail fan, green, pushed by the solar wind. Its magnitude was greater then, between 6 and 8, which allowed to see her among the stars, with binoculars or a small telescope in the constellation Hercules, near the globular cluster M 92.
Comet C/2009 P1 Garradd remained visible in the sky for several months, offering fans a good show well equipped. It was located closer to the Sun in December 2011. The comet Garradd is a comet relatively high, but never really come near the Earth or the Sun in its journey through the solar system. Very remote, it feels like to move very slowly.

NB: Comets are small spheres of ice traveling between the stars, and were surprised by the Sun.
Their orbits are elliptical trajectories, extremely eccentric around the Sun.
When a comet approaches the Sun, the outer layer vaporizes and forms a gaseous envelope (coma). Solar radiation exerts pressure on the coma and force particles and gases away from the Sun, forming a glowing tail of ionized particles.
Comets shine in the memory of mankind.
They have long been the misfortune, disaster and upheaval.
A comet is not the messenger of doom, but the guardian of the past, one that holds the key to our origin.
In the 19th century with the separation of science and religion, the image of the comet is no longer negative. They can contemplate, for weeks, before they disappear, to return, 10, 100 or 3000 years later.
Comets are dirty icebergs traveling in space, swarming primordial matter.
