The smallest of the eight planets in the Solar System will cross in front of the sun; the Argentina will have a “preferential plates” to see for seven hours
the solar event of the year will transit to star the smallest of the planets in our solar system: Mercury. For several hours, Mercury will pass in front of the sun, covering all your hard end to end.
This is one of the most curious and interesting astronomical phenomena that can be observed from Earth and will happen after tomorrow Monday, may 9, when Mercury transits in front of the solar disk partially blocking its light and its entire trajectory can be seen from most of the country.
“the event will begin at 8:12 pm of morning and will end at 15:42 pm. This phenomenon, which occurs 13 to 14 times per century is not the case for ten years, and Argentina will have during more than seven hours of the event, a privileged place for watch, something like a prime audience “, explained the NATION, Mr. Mariano Ribas, by the area of Astronomy Planetarium Buenos Aires, Galileo Galilei.
the rare frequency of this event is because Mercury’s orbit is inclined to the orbit of the Earth and, therefore, not only enough that the planet is between Earth and the Sun, but also must be crossing the plane Earth orbital.
From Obsevatorio Astronomical Cordoba, astronomers point out that “the 8 planets of the solar system, only Mercury and Venus can pass between Earth and the Sun, partially eclipsing” . And they point out that previous transit of Mercury occurred in 1986, 1993, 1996, 2003, 2006 and the next will be in 2019, 2032, 2039, 2049.
That and the size it is the smallest planet the solar system and the star, is called in astronomical jargon one microeclipse. In the case of Venus transits occur 2 times per century. This makes it ever happens any of these astronomical events we want to observe as if only happened once.
How to observe the phenomenon?
“When the small planet parade ahead of sun aid of a telescope will be necessary as it is not visible to the naked eye, “stand out from the Planetarium. “We will have six telescope with corresponding filters and special order to appreciate the full extent techniques,” said Ribas, who stressed how dangerous it is for the eyes if you do not look with the care they needed because “the sun will burning eyes. “
So they emphasize the importance of not looking at the Sun directly under any circumstances (or naked eye or with sunglasses, or non-specific telescopes <. / p>
look this phenomenon is necessary to have a sunscreen and a suitable optical instrument that allows amplify the silhouette of Mercury. One of the best ways to enjoy this event is to project the solar disk on a screen to avoid risks and can be observed by several people at a time, as will happen in the Planetarium.
What will be?
In short, you will see a black “dot” passing (very slowly) in front of the solar disk
. precise numbers: the apparent diameter of the Sun (not actual size) is 0.5 °. O 1800 arcsec. The apparent diameter of Mercury in transit will be 10 “
ie. During the phenomenon, Mercury will be 180 times smaller than the Sun
Where can observe.
the Planetarium of the City of Buenos Aires, Galileo Galilei organize a special, free public event, to observe throughout its development. the observations of the transit of Mercury will be in charge of personnel Planetarium, which it will show the public through telescopes, filters and other special techniques. the date is Monday, May 9, from 8:30 am until after 15 hours.
in Cordoba, the Astronomical Observatory Córdoba opens its doors to the public who wants to approach. it will also be on Monday from 10 am to 13 hours. the observatory will have three solar telescopes so that those who do not have the opportunity to do so in their homes, approach scientific institution and to observe. Stargazers accompany the event providing expertise to visitors.
