Tell us what the transit of Mercury
Fabrice Richard, head of e astronomi club Saint-Exupery cultural center in Amneville: “We talk about transit when Earth, Mercury and sun are perfectly aligned. This configuration can only occur when the small planet is at its aphelion or perihelion. Transits have also the peculiarity to occur systematically in May or November.
From the perspective of an observer on Earth, Mercury is farthest from the sun in May (its aphelion) and closest to the sun in November (perihelion). The first observation of a transit of Mercury dating back to November 7, 1631. He was then predicted by Johannes Kepler shortly before his death. This forecast was accurate enough since the famous astronomer was mistaken in his estimate of five. A feat for the time.
With the current knowledge, however we can announce that the transit of May 9 will begin at 13 h 12 to finish at 20 h 42. The observers then see a small dot black move very slowly across the sun. “
Why is this phenomenon unique?
” It is exceptional because of its rarity. Although more frequent than those of our closest neighbor Venus, Mercury transits visible from Earth occur less than 15 times per century. And it is still necessary that this be observable in our latitudes: the transits of May 1937 and November 1999 were such was visible from the southern hemisphere. “
Should we take precautions to observe this phenomenon?
” It will be a magnificent spectacle provided to protect the eyes. In fact, you never quite remember it is dangerous to observe the sun. Therefore, for the occasion, many telescopes with solar filters will be made available to the public to follow this event live. This animation will be framed by the club members. They live explain the phenomenon and answer any questions. “
