The transit of Mercury is in a straight line crossing the orbit of Mercury with the Earth and the Sun during the movement of the Sun. As Mercury moves in the face of the Earth, Mercury hides a small part of the Sun in front of the viewer of the Earth (as it happens during the solar eclipse). The Mercury looks like a black dot compared to the large radius of the sun. This black dot is only 0.1 percent subject to the sun’s radium. Transit can be seen from the part of the world where the day will be.
Since Mercury and Venus are located between the Earth and the Sun, we can only see in this type of phenomenon of Mercury and Venus from the Earth. Mercury is moving closer to the sun. The Venus is after Mercury. In the case of Mercury, these transitions occur much more frequently than the transit of Venus, occurring approximately 13-14 times per century. Transitions to Mercury occur in May or November.
Last, the transit of Mercury is seen on Monday, November 11, 2019. Skywatchers around the world, including the United States, Africa and Europe, had the opportunity to witness the rare heavenly phenomenon. It starts at 12:00 PM and ends at 6:00 PM of GMT time.
It will be seen again on November 13, 2032, after the 11th of November, 2019. Earlier, there are three more transits of Mercury were seen in this century the date on May 9, 2016, November 08, 2006 and May 07, 2003. Mercury takes 88 days to orbits the sun. As a result, the transit of Mercury is expected to be seen every 88 days. But we do not always see because it orbits another way.
The transit of Mercury is not visible to the naked eye. It can be seen in certain telescopes and binoculars. But in this case, the special warning is that the Sun filter must be added to the telescope and binoculars. Without the filter, you cannot try to see. In this case, you will lose sight of your eyes forever. If you do not have experience in this regard, it is best not to look at the sun.

Transits of Mercury can only occur when the Earth is aligned with a node of Mercury’s orbit. Currently that alignment occurs within a few days of May 8 ( descending node ) and November 10 ( ascending node ), with the angular diameter of Mercury being about 12? for May transits, and 10? for November transits. The average date for a transit increases over centuries as a result of Mercury’s nodal precession and Earth’s axial precession .
