The video, which shows the passage of mercury over the disk of the Sun, introduced the American space Agency NASA. The opportunity to observe how the nearest planet to the Sun is between the sun and Earth, people seem to be only about 13 times every century.
In the video, which the Agency posted on his Twitter page, you can see a small black dot representing mercury, from left to right passing through a huge slowly rotating ball of the Sun, which you can see the line of the force fields. An event that in reality lasted approximately 7.5 hours, the video is speeded up to 16 seconds. The Agency also published a two-minute video dedicated to transit.
This year the transit of planet nearest to the Sun fell on 9 may, Victory Day. It can be observed in the shaded binoculars, as well as organized during a NASA webcast. Such events are of interest for both the Amateur and professional astrophysicists, because it allows you to collect a lot of new information about celestial bodies, caught between the earth and the Sun.
The passage of mercury over the solar disk usually happens in may or November. The next time, according to the calculations of astrophysicists, it was possible to observe November 11, 2019. However, it is much more frequent than transits of Venus — it was held in 2012 and next time will only happen in 2117-M. Other planets between Earth and sun is not.
The first observation of the passage of mercury across the solar disk occurred on 7 November 1631.
