Astronomy fans are celebrating. A spectacular event will come to Earth in a few weeks. It’s the comet Hartley 2, a very distant asteroid that will cross several constellations and which finally will finally pass near our planet for the enjoyment of all those people who know where to focus their telescopes.We must remember that this type of event occurs very rarely in the life of a human being. (theories on the origin of life on our planet) The passion that astronomy enthusiasts show for comets deserves that events like this happen once in a while. Not so much by the visual spectacle that dominates the night sky when one of these stars goes to describing a more or less visible path, but rather by how rare that these events are. He is not expected to pass more than 3 or 4 times every hundred years, therefore, is a very attractive event for all those who appreciate this kind of appearances so scarce in the history. The star, whose nucleus is approximately 1.5 kilometres in diameter, will come to your closest point to the Sun on October 28, allowing perfect viewing on this date on the basis of data given by Nasa, but from 8 days before, you may notice with a conventional telescope. Hartley 2 becomes a mere 11 million kilometers from Earth.
It will not look like a typical star. Rather will be a dark blue point where barely visible is the queue that this type of stars often wear after Yes. All those who want to admire the beauty of this event cosmic only must equip with a domestic telescope or even binoculars. Depending on weather conditions, you can see even with the naked eye when it reaches its point of maximum closeness to the Earth. In the coming days, experts aim to follow its trajectory by the constellations of Cassiopeia, Perseus and Auriga and capture images of this magnificent phenomenon.NASA does not want to miss the opportunity to investigate Hartley 2 and for this they have prepared the EPOXI spacecraft to approach and fly over the Comet about scarce 700 miles away. This will happen on November 4, 2010, so we have to be prepared to attend a series of photographs that will surely be for the history of astronomy. They will be nothing less than 64,000 images of its surface. For this probe is equipped with two telescopes and an infrared spectrometer, it is considered that the detailed study of the comet will extend about two months. Listening to that event which promises strong sidereal emotions.
